60-1: Why can't I boot from my SCSI disk when an IDE / EIDE (ATAPI) disk is installed? (Article #990823-0001)

Description:
Why can't I boot to my SCSI hard drive an IDE / EIDE (ATAPI) hard drive is installed?. How can I change the boot order of the I/O controllers?

This information applies to the following products:

- 1515, 1520 / 1522 series, 1530, 1540 / 1542 series - ISA SCSI Card(s)

- 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series, 19160, 29160N, 29160, 39160 - PCI SCSI Card(s)

This information applies to the following Operating System(s):

- All PC
Solution:
On most older motherboards the IDE controller takes priority over the SCSI controller in the boot order. On these old motherboards there is no CMOS / BIOS utility option to change the boot order from IDE first to SCSI first. Because of this, you must completely disable the IDE controller to boot to a SCSI hard drive connected via an Adaptec SCSI controller card.

Most new motherboards have an option in their CMOS / BIOS setup utility to arrange the boot order of the I/O controllers. These newer motherboards allow you to boot from a SCSI hard drive connected via an Adaptec SCSI controller card and also keep your IDE controller enabled for support of your IDE devices.

The boot order of the I/O controllers is a function of the motherboard's CMOS / BIOS setup - it is not a function of the SCSI controller's BIOS. Please check with the motherboard / computer manufacturer for a CMOS / BIOS update that includes the option to choose the boot order of the I/O controllers. If this feature is not available through a CMOS / BIOS update, then you must disable the IDE controllers on the motherboard when you booting from a SCSI hard drive. NOTE: You may boot from an IDE hard drive and still use your SCSI devices attached via an Adaptec SCSI controller.

Please see the following ASK article for more information:

How can I determine the boot order of my I/O controllers (IDE / SCSI)? (REF#990426-0022)

60-2: Frequently Asked Questions about the 29160 and 39160 64-bit PCI SCSI Cards (Article #000203-0004)

Description:
Frequently Asked Questions about the 29160 and 39160 64-bit PCI SCSI Cards

This information applies to the following products:

- Adaptec SCSI Cards 29160 and 39160

This information applies to the following Operating System(s):

- All / PC
Solution:

Q. Do the 29160 and 39160 support all PCI 2.1 compliant modes?

A. Yes, both the 29160 and 39160 should operate properly in PCI based motherboard that are fully PCI 2.1 compliant - in either 32 bit (3.3V or 5V) or 64 bit (3.3V or 5V) PCI slots.

The PCI specification allows for multiple clock speeds and bus voltages. At 5V, PCI cards operate at 33 MHz. At 3.3V, PCI cards may operate at either 33 or 66 MHz depending on the motherboard. These variables are independent of the PCI bus width (i.e., 32 or 64 bit).

Q. Are the 29160 and 39160 backwards compatible with 32-bit PCI slots?

A. These cards will operate in most motherboards with 32-bit PCI slots. The motherboard must be fully PCI 2.1 compliant. Check with your motherboard manufacturer to see if it is fully PCI 2.1 compliant.

Q. Is the 50 pin connector on the 39160 part of Channel A or Channel B?

A. The 50 pin connector on the 39160 is part of Channel A.

60-3: Is it necessary for the last SCSI device on the cable to be terminated? (Article #990428-0003)

Description:
Is it necessary for the last SCSI device on the cable to be terminated?

This information applies to the following product(s):
· 1505 series, 1510 series, 1515, 1520 series, 1530p, 1540 series, 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· All / PC
· Mac OS (Adaptec PowerDomain SCSI cards only)
Solution:
It is mandatory that on each end of the SCSI bus be properly terminated. The SCSI bus, can be terminated by either a terminator block, or a SCSI device. Improper termination could cause your SCSI card not to initialize, cause the driver to not to load and could even be the possible source and cause of data corruption.

If you are running a dual channel SCSI controller, such as the AHA-3940AUW or a segmented controller, such as the AHA-2940U2W, each channel or segment is considered, a separate, SCSI Bus and must be terminated properly.

60-4: How do I access my SCSI CD ROM under DOS? (Article #990429-0000)

Description:
How do I access my SCSI CD ROM under DOS?


This information applies to the following product(s):

- 1505 series, 1510 series, 1515, 1520 series, 1530p, 1540 series - ISA SCSI Card(s)

- 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series, 29160N, 29160, 39160 - PCI SCSI Cards

This information applies to the following Operating System(s):

- DOS
Solution:
To access your SCSI CD ROM under DOS you simply need to load the DOS driver / ASPI manager for your SCSI card, the ASPI CD ROM driver, and the Microsoft CD ROM program. The ASPI manager and the ASPI CD ROM driver need to be loaded in your config.sys. The Microsoft CD ROM program needs to be loaded in your autoexec.bat.

You can go directly to Adaptec's DOS Configuration Utility which contains step by step instructions and will automatically generate the command lines you need to place in your CONFIG.SYS and AUTOEXEC.BAT files based on the particular Adaptec SCSI card you're using. The URL is as follows:

http://www.adaptec.com/support/faqs/dosdrvraccess.html

You can download all of the DOS drivers for Adaptec's SCSI cards in one package called DOSDRVR.EXE by clicking here.

60-5: My PCI card was detected, but has a yellow ! on the driver in Device Manager. (Article #990427-0020)

Description:
My PCI card was detected, but now has the yellow ! on the
driver in Device Manager.


This information applies to the following product(s):
· 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· Windows 95, Windows 98
Solution:
Restart the system and bypass the real mode drivers. (When the
screen displays the message: Starting Windows95. . ., press the F8 key
on your keyboard. Select "Step-by-step confirmation" from the Windows
Startup menu. Answer 'yes' to all prompts EXCEPT for "Load all device
drivers Config.Sys" and "Load all device drivers Autoexec.bat". Answer
no to those two prompts.) If the driver still has a yellow !, update the driver from
the Adaptec OLS (on-line services). If the
driver is updated but still has a yellow !, select the 'Computer' icon at the
top of the Device Manager window. Double-click on the icon. The system
IRQ resources are listed. Verify the SCSI card is listed with a
non-shared IRQ and there is not a ! on the listed IRQ or on any other
devices. A yellow ! on the SCSI card or other devices indicates a IRQ
conflict. Try to correct an IRQ conflict in the system CMOS. If there is no
apparent conflict, check System Performance for details of the problem.
A solution may require installation of a anti-virus program, or reformatting
the hard drive.

60-6: How do I assign the Interrupt Request (IRQ) for my PCI SCSI card? (Article #990412-0000)

Description:
How do I set the Interrupt Request (IRQ) for the adapter?

This information applies to the following product(s):

- 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series - PCI SCSI Card(s)

This information applies to the following Operating System(s):

- All / PC
Solution:
The PCI specification allows the motherboard manufacturer to determine the IRQ assignment for each PCI device. Check with the motherboard / computer manufacturer for the specific PCI configuration details of your system.

Here are some basic steps that can assist the motherboard in correctly allocating resources to your PCI devices and / or resolve existing IRQ conflicts:

  1. Move the PCI SCSI card to a PCI slot that is not forced to share an IRQ with any other PCI, AGP, or ISA slot - usually the PCI slots in the middle of the PCI expansion bus fit this description - you'll need to check with the motherboard / computer manufacturer for the specific PCI configuration details of your system
  2. Check with your video card / display adapter manufacturer to see if your specific video card requires an IRQ allocation - most motherboard CMOS / BIOS setup utilities have an option to disable the allocation of an IRQ to the AGP slot - disable this option only if you have verified that your video card does not require an IRQ
  3. Verify that all IRQs not specifically required for ISA devices are set to "Available" or "PNP ISA/PCI" in the motherboard CMOS / BIOS setup utility
  4. Verify that all devices not being used are disabled so that the resources they are being allocated can be freed up for allocation to another device - this is accomplished through the motherboard CMOS / BIOS setup utility (Example: if you're not using the onboard COM / Serial port on your motherboard, you can usually disable this chipset and free up the IRQ it's currently being assigned.)

If you're working with Microsoft Windows 95, 98, or NT, please see the following Microsoft Tech Net articles for more details about PCI resource allocation:

60-7: FDISK reports 'No Fixed Disks Present' but card's BIOS sees the drive. (Article #990816-0021)

Description:
FDISK reports 'No Fixed Disks Present' but the SCSI Host Adapter's BIOS scans and finds the hard drive.

This information applies to the following product(s):
- 1515, 1520 / 1522 series, 1530, 1540 / 1542 series - ISA SCSI Card(s)
- 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series - PCI SCSI Card(s)

This information applies to the following Operating System(s):
- DOS, Windows 3.x, Windows 95, Windows 98
Solution:
If this is the only hard drive in the system and it is SCSI, and there is a built in IDE controller on the motherboard, make sure the IDE controller is disabled or set for none (no hard drives installed.

Double check and set the SCSI ID of the hard drive to ID=0.

Boot without loading any DOS drivers in the config.sys or autoexec.bat files. Renaming the config.sys and autoexec.bat files will keep any DOS drivers from loading. Older DOS drivers may interfere with FDISK, and prevent it from seeing any attached hard drives.

As a last resort, load DOS drivers ASPIxdos.sys (the correct ASPI2DOS.sys, ASPI4DOS.sys, or ASPI8DOS.sys for your SCSI Host Adapter) and ASPIDISK.sys and us the Adpatec AFDISK program to create a small partition. Once the partition has been created, remove the drivers, and again try and to run FDISK, if it finds the hard disk, remove the partition created with AFDSIK and create a new partition with FDISK. If the primary partition created is smaller than the full capacity of the drive, you must make partition 1,(the primary partition) active. This is also done with the FDISK utility.

After you have created a partition on the drive with FDISK, you will need to reboot your system and run the Format/s command on the partition, to high level format it and /s to transfer the system files.

60-8: Installing a PCI Adaptec host adapters in Windows 95 or 98... (Article #990428-0098)

Description:
What is the procedure for installing a PCI SCSI card in Windows 95 or 98?

This information applies to the following product(s):

· 2902 series, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):

- Windows 95
- Windows 98
Solution:
  1. Before installing the host adapter in your system, check for available resources. Look in Device Manager under Computer Properties, here you can obtain a list of resources (IRQ, DMA, I/O Port & Memory) that are currently in use by the system, determine if there are available resources. To get to this location; open Control Panel, then double click on System Icon, select the Device Manager tab, double click the computer icon at the top of the list, this will open the Computer Properties. All currently used resources will be listed. If there are no available Interrupt request (IRQ) you will need to contact your system manufacturer to assist in freeing up an interrupt request (IRQ) before you can proceed with the installation. Some systems may allow PCI host adapters to share resources.
  2. There is no way on a PCI adapter to physically, or through SCSI Select settings to assign resources on the PCI adapters. The system BIOS does all of the resource allocation for PCI adapters. On some systems you may have options in the system CMOS listed under PCI/PNP configuration that may allow some resource allocation. You may also be able to effect resource allocation by changing PCI slots.
  3. Before installing the adapter in Windows 95 make sure that you see a BIOS banner for the adapter during post. This BIOS information will show you what adapter you have installed, the BIOS version and what devices are connected to the adapter. If the host adapter has a BIOS, then this information must appear for the adapter to install properly in Windows 95. If the host adapter does not have a BIOS chip you will not see this information during post and must install the adapter driver in Windows 95 before you can see the adapter and device in Windows 95.
  4. If you do not get a BIOS Banner during post for a Host adapter that has a BIOS chip, or you do get a BIOS banner but get an error "Host Adapter Configuration Error" do not proceed with installing the adapter in Windows 95 until this has been resolved. This error at system boot indicates the PCI interrupt has not been configured correctly. Check the system CMOS/BIOS setup for PCI slot enable, bus mastering enable, IRQ triggering set to Level, enough available IRQs reserved for PCI/PNP. These settings can usually be found in the system CMOS under PCI or PNP configuration. Also try installing the adapter in another PCI slot.
  5. Windows 95 will automatically detect the adapter during boot. You will be prompted that Windows 95 has detected new hardware. If the driver source is already on you PC system Window 95 will inform you that it is installing your driver and prompt you to restart your system once the driver is installed. If the driver source is not already on your PC system then Windows 95 will prompt you for a drivers disk from manufacturer or the Windows 95 CD-ROM.
  6. Once the system is rebooted you can verify that the driver is loaded successfully in Windows 95 Device Manager. In Control Panel, double click on the System icon, then open Device Manager, there should be a listing for "SCSI controllers" the driver should be listed with no yellow exclamation or red X. You can review the resources the driver is using by double clicking on the driver and selecting the Resource tab, this will also give you conflicting device list information.
  7. Once the driver is installed if the system fails to boot to Windows 95 when you reboot this is an indication of a resource conflict. If the system locks up with memory errors or with no video, this could be a BIOS address conflict. Update the system BIOS to the most recent version. If the system locks up or freezes on the driver load, check for IRQ conflict. Put the adapter in another PCI slot (primary or 1st slot preferred), check the system CMOS setup for any PCI slot or IRQ options that will allow you to reserve an IRQ for PCI/PNP.
  8. Once in Windows 95 and there are no boot problems if the driver still has a yellow exclamation or red X, then update the driver with the latest driver from the Adapter Web. You can update the driver by going to Device Manager, under SCSI Controllers double click on the driver and select Driver tab, select the button "Update Driver", this will allow you to update the driver. You can also just copy the updated driver to the Windows/system/iosubsys directory in Windows explorer, this will overwrite the current driver with the latest.
  9. If installing a PNP non PCI adapter in Win95 and the PNP does not appear to be loading the driver then disable the PNP on the adapter. Check adapter documentation for instructions on disabling PNP on this adapter then use the instructions for "Installation non PNP/PCI Adaptec host adapters".

60-9: NT reports 'Inaccessible boot device' after changing SCSI controllers... (Article #990824-0005)

Description:
NT reports 'Inaccessible boot device' after changing SCSI controllers. How do I resolve this?

This information applies to the following product(s):

- 1505 series, 1510 series, 1515, 1520 / 1522 series, 1530, 1540 / 1542 series - ISA SCSI Card(s)
- 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series - PCI SCSI Card(s)

This information applies to the following Operating System(s):

- Windows NT 4

Solution:
Although it may be possible to change the boot SCSI controller in Windows NT system, it is not recommended by Microsoft. Tech Net article Q198859 states:

"NOTE: Attempting to start Windows NT with a SCSI hard disk controller other than the one Windows NT is installed and configured for is not supported. Customers should attempt this workaround at their own risk. "

See the following URL for Microsoft's suggested workaround if you cannot switch back to the original SCSI controller:

http://support.microsoft.com/support/kb/articles/q198/8/59.ASP

If you're switching between a 2940UW and a 2940U2W, then you can also try the following steps:

  1. Boot to a command prompt from a bootable diskette
  2. Copy the AIC78U2.SYS driver from the driver diskette into the C:\WINNT\SYSTEM32\DRIVERS directory
  3. Delete or rename the AIC78XX.SYS driver in the \WINNT\SYSTEM32\DRIVERS subdirectory
  4. Rename the AIC78U2.SYS to AIC78XX.SYS
  5. Restart the system and Windows NT should now boot properly
  6. Once booted, open the "SCSI Adapters" control panel, select the "Drivers" tab, and click on the "Add" button
  7. Install the driver for the 2940U2W from the driver disk (the correct driver name and description for the 2940U2W)
  8. Remove the entry for the 2940UW driver and reboot
  9. The system should now boot into WIndows NT via the 2940U2W with its own driver properly named

60-10: Why must I use an IRQ above IRQ 09 for my AVA-2906 PCI SCSI card? (Article #990722-0000)

Description:
Why must I use an IRQ above IRQ 09 for my AVA-2906 PCI SCSI card?

This information applies to the following products:

- 2906 Series PCI SCSI Card(s)

This information applies to the following Operating System(s):

- All / PC
Solution:
The Adaptec AVA-2906 Installation Guide incorrectly states the following:

"Note: Do not use an IRQ below IRQ 09 for a SCSI Card 2906. Do not allow the SCSI Card 2906 and another card to share the same IRQ."

This statement can be ignored. If your motherboard assigns the AVA-2906 an IRQ below IRQ 09 it means that the IRQ was available for PCI allocation. For more information on PCI IRQ allocation Click Here.

60-11: What is bus mastering? (Article #990429-0007)

Description:
What is bus mastering?

This information applies to the following product(s):
· 1505 series, 1510 series, 1515, 1520 series, 1530p, 1540 series, 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series


This information applies to the following Operating System(s):
· All / PC
Solution:
Bus mastering is a method of transferring data through a Bus in which the device takes over the Bus and directly controls the transfer of data to the computers memory. Bus mastering uses DMA (Direct Memory Access) and a Bus mastering controller speeds up the system by by-passing the CPU when it addresses memory. This frees the CPU to process other commands that are in the cache. Bus mastering PCI cards do not use a DMA channel, but can still directly access memory without going through the CPU.

  5. Verify that your CDR / CDRW drive has the latest firmware revision - see the following URL for links to many CDR / CDRW manufacturers:

    http://www.adaptec.com/adaptec/partners/cdrec.htmll

  6. Verify proper cabling with known good cables (no bent or broken pins)
  7. In some case it may be necessary to remove all devices from the SCSI bus other than the CDR / CDRW and boot hard drive
  8. If there are SCSI hard drives attached to the same SCSI card as the CDR / CDRW, verify that the jumper settings on the drive are properly configured:
    • Termination - enabled or disabled - depends on the location of the drive in the SCSI chain
    • Termination Power - set to "Receive from SCSI BUS" or "Disabled" if you're using an Adaptec SCSI card
    • Parity - enabled
    • Check with the manufacturer's documentation on the hard drive for more information

60-13: My SCSI device is not detected by the card's BIOS. Why? (Article #990426-0009)

Description:
My SCSI device is not detected by the card's BIOS. Why?


This information applies to the following product(s):
· 1520 series, 1530p, 1540 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· All / PC
Solution:
Most devices will be detected with the default BIOS settings. Some
devices (scanners, CD-ROMs, slide scanners, tape drives) do not
support BIOS functions such as "Sync Negotiation", "SCSI Bus Reset"
or "Disconnect" and may not be detected. For some non-wide devices,
such as some CD-ROM readers, the default value of a wide SCSI card
for "Initiate Wide Negotiation" or "Parity" must be disabled for the device
to be sensed. Device detection at the BIOS level can be initiated by
selecting the SCSI Disk Utility option from "SCSI Select". If the device
cannot be detected, or the system locks during the bus scan, changing
the parameters should work. If changing parameters in the BIOS does
not allow the device to be detected, check cable(s), SCSI ID
configuration, termination, total cable length, or replace the device with a
known good device.

60-14: Adaptec SCSI Driver loads with a yellow ! - Code 30 in Windows 9x (Article #990713-0000)

Description:
After installing the SCSI adapter, the driver in Windows 9x has a yellow ! in Device Manager. The Device Status for the adapter indicates "This device is using an Interrupt Request (IRQ) resource that is in use by another device and cannot be shared. You must change the conflicting setting or remove the real-mode driver causing the conflict (Code 30)"

This information applies to the following products:

2902 2910 Series 2930 Series 3940 Series 2930U2 Series 2906 Series 2920 Series 2940 Series 2940U2W Series 3950U2 Series PCI SCSI Card(s)

This information applies to the following Operating System(s):

Windows 98 and Windows 95
Solution:
This usually indicates a conflict between a Real Mode (DOS) driver and the Protected Mode driver for the SCSI adapter. The Real Mode drivers in question, often are used for an IDE CD-ROM Drive or a Sound Card.

Go to Start->Run, type "Sysedit" in the Run window and press "OK".

Examine the AUTOEXEC.BAT file and attempt to locate any lines which may refer to a file with an .exe or .com extension. Try to find out from the name of the file or the name of the directory for which it loads if it relates to a Sound Card. If it does, go to the beginning of the specific line and type "REM ", then save the file.
Examples of lines which may cause this behavior:
LH C:\WINDOWS\SYSTEM\ASP4DOS.COM
LH C:\WINDOWS\AU30DOS.COM
C:\PROGRA~1\CREATIVE\SBLIVE\DOSDRV\SBEINIT.COM
Most of the time, these lines are used for Sound Blaster Emulation under DOS and will not affect your sound card drivers in Windows. Contact your sound card / system manufacturer to get more details about the respective files.

While in Sysedit, also examine the CONFIG.SYS file and locate any lines that load drivers for an IDE CD-ROM. These lines will most of the time start with "DEVICE" or "DEVICEHIGH". REM out the specific lines and save the file.

Close Sysedit. You will need to shutdown and restart Windows for these changes to take effect.

60-15: Adding a SCSI card and a hard drive changes the drive letter assignments. Why? (Article #990426-0023)

Description:
I am adding a SCSI card and a hard drive to my existing
system. When the system boots, the hard drive attached to the
SCSI card is detected, but my existing secondary partition(s) on my
drives have their drive letters change. How can I correct this?


This information applies to the following product(s):
· 1515, 1520 series, 1530p, 1540 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· DOS, Windows 3.x, Windows 95, Windows 98
Solution:
The motherboard BIOS assigns drive letters for storage devices in the following order: Primary partitions on hard drives, Logical hard drives in Extended partitions, then CD-ROMs. If an existing hard drive has a Extended (secondary) partition, the detection of a new BIOS controlled physical hard drive with a Primary partition will cause the new device to be assigned the next available drive letter, which forces the Logical partition's drive letter to be shifted up.

If the new drive is not on the boot controller, disable the Host Adapter BIOS in the Advanced Configuration of the SCSI card's SCSI Select setup.

If the new drive is on the boot controller, set the Include In BIOS Scan option to No in the SCSI Device Configuration screen of the SCSI card's SCSI Select setup. This option is not available on all SCSI cards.

In addition, the new hard drive can be partitioned without a Primary partition, using only an Extended partition). Then the Logical partitions inside the Extended partition will receive drive letters after those on the first (old) hard drive.

60-16: The system does not boot after installing the card. Why? (Article #990426-0001)

Description:
When the SCSI card is installed, my
system fails to boot. If I remove the adapter, the system boots
normally. Why?


This information applies to the following product:
- 1520 series, 1530p, 1540 series, 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System:
- All / PC
Solution:
This is a symptom of a resource conflict. This could be a BIOS
address conflict, card conflict or an IRQ conflict.

1.If the system locks up with no video, or memory errors, this could
be a BIOS address conflict. Update the system BIOS to the most
recent version.
2.If the system locks up with scrambled video, or the graphics are
incorrect, check to see if a PCI video adapter is installed. Replace
with an ISA video adapter. If the system boots normally, check
with the adapter vendor for BIOS update or known conflicts.
3.If the system locks up or freezes on driver load, check for an IRQ
conflict. Remove all other adapters except for the hard drive
adapter, SCSI card, and the video adapter. If the system boots
normally, install the adapters one at a time until the boot fails
Determine the irq of the adapter and change to another available
irq, or change the CMOS IRQ listing to make that specific IRQ
‘not available’ to the PCI bus.

60-17: The adapter recognizes the drive on boot up but gives 'Drive not ready'. Why? (Article #990429-0009)

Description:
The adapter recognizes the drive on boot up but gives "Drive not ready". Why?


This information applies to the following product(s):
· 1515, 1520 series, 1530p, 1540 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· All / PC
Solution:
You will want to make sure that the drive is set to spin up (or start its' spinning cycle) when power is applied to the computer. You can also enable the 'Send Start Unit' command, within SCSISelect and SCSI Device Configuration, on many different models of Adaptec host adapters. This is a software command, which is sent to the hard drive to start spinning. Double check to make sure all cables are seated properly.

60-18: After installing a SCSI CD-ROM drive, I can't access my IDE CD-ROM. (Article #990427-0008)

Description:
I have an IDE CD-ROM drive which was working. I installed a
SCSI CD-ROM on my Adaptec SCSI card. Now I can use my SCSI CD-ROM
but don't see a drive letter for my IDE CD-ROM.


This information applies to the following product(s):
· 1505 series, 1510 series, 1515, 1520 series, 1530p, 1540 series, 2902, 2906 series, 2910 series, 2920 series, 2930 series, 2940 series, 3940 series, 2940U2W series, 2930U2 series, 3950U2 series

This information applies to the following Operating System(s):
· DOS, Windows 3.x
Solution:
When EZSCSI installs, it edits the Autoexec.bat for the naming
convention used for MSCDEX.EXE. It may also overwrite any existing
naming convention. Check the Config.Sys for the device driver of your
IDE drive. Note the naming convention and add to the MSCDEX.EXE
line. For example, your IDE driver may have /D:MSC0001 as the naming
convention. Add this to the MSCDEX.EXE line so that both naming
conventions are listed, i.e., /D:ASPICD0 /D:MSC0001. The naming
convention which appears first will get the first available drive letter, or, if
it has the /L:x switch(x is the starting drive letter), will start at the
assigned drive letter

60-19: Installation of non PNP/PCI Adaptec host adapters in Win 95 or 98 (990428-0097)

 

Installation of non PNP/PCI Adaptec host adapters in Windows 95 or 98. (Article Number 990428-0097)

Description:
I'm having a problem installing my ISA SCSI card. It doesn't seem to be a plug and play card. How do I install a non-plug and play Adaptec ISA SCSI card in Windows 95 or 98?

This information applies to the following product(s):

· 1505 series, 1510 series, 1515, 1520 series, 1530p, 1540 series - ISA SCSI Card(s)

This information applies to the following Operating System(s):

- Windows 95
- Windows 98
Solution:
  1. Before installing the host adapter in your system, check for available resources. Look in Device Manager under Computer Properties, here you can obtain a list of resources (IRQ, DMA, I/O Port & Memory) that are currently in use by system, determine which resources are available to set your host adapter to. The steps to get to this location are; open Control Panel, then double click on System Icon, select the Device Manager tab, double click the computer icon at the top of the list, this will open the Computer Properties. All currently used resources will be listed. If there are no available Interrupt request (IRQ) you will need to contact your system manufacturer to assist in freeing up an interrupt request (IRQ) before you can proceed with the installation.
  2. Once you have determined what resources are available in your system, set the host adapter to the available resources and install it in your system.
  3. If your system supports PCI you will want to get into the system setup (CMOS, BIOS) during post to make sure that the resources you are using for the host adapter are not being reserved for PCI. Some systems will have a listing or IRQ (Interrupt request) setting that you can set to either PCI/PNP or Legacy ISA, set the IRQ the host adapter is using to "Legacy ISA".
  4. To install the host adapter open the Control Panel and select "Add New Hardware" icon. This will bring up the "Add New Hardware Wizard", select "No" when you are prompted if you want to automatically search for new hardware. Select "SCSI Controllers" and select the Adaptec Host adapter you want to install. The install program will ask for the driver source if it is not already on your PC system. You must have access to the distribution disks or WIN 95 CD-ROM in order for the installation to proceed.
  5. Verify that the resources Windows 95 chose are the same as the card resource settings.
  6. If the resources that Windows 95 has chosen for the adapter driver differ from the resources the host adapter is set to, then change the resources on the adapter to the Windows 95 settings.
  7. Restart your system. To verify that the Adaptec driver is loading properly, look in Device Manager under "SCSI Controllers". The driver if properly loaded it will be listed with no Yellow exclamation mark or red X present over the adapter icon.
  8. To verify if all of the devices you have connected to the adapter are being detected by Windows 95 you can check in Device Manager, by selecting the "View Device by Connection", then on the list double click on the "Plug and Play BIOS", the driver will be listed. Double click on the driver for the adapter you have installed and all connected devices should be listed.
  9. You can obtain information on device settings in Device Manager by looking under the appropriate category listing. CD-ROMs will appears under the CD-ROM listing, hard drives and removable media will be listed under Disk Drives. Since scanners do not have embedded driver support, you will be required to install a scanner driver. Once this is installed it will be listed in Device Manager under Scanner.
