SCSI Controller
Jump to the self-diagnostic flowchart, or select the specific problem you're having with your SCSI controller:
 |
The system board doesn't detect the SCSI controller. |
|
The SCSI controller isn't detecting my SCSI devices. |
|
My operating system doesn't see my SCSI controller. |
THE SYSTEM BOARD DOESN'T DETECT THE SCSI CONTROLLER
THE SCSI CONTROLLER ISN'T DETECTING MY SCSI DEVICES
MY OPERATING SYSTEM DOESN'T SEE MY SCSI CONTROLLER
SELF-DIAGNOSTIC FLOWCHART
ADD SCSI CONTROLLER TO PCI BUSMASTERING SLOT

LOAD SCSI CONTROLLER DRIVERS
1. PCI SCSI controller requires a PCI busmastering slot. If the SCSI
controller is not in busmastering slot, most likely it will not work.
2. Consult your system board manual to determine which PCI slots are
busmastering. Typically, the PCI slot closest to the processor and/or AGP
slot is a busmastering PCI slot.
3. If your SCSI controller is integrated onto the system board, make
sure the SCSI controller is enabled in the BIOS.

1. Make sure your SCSI devices are configured correctly. That is, make
sure their SCSI ID and termination are setup properly.
2. If the SCSI controller isn't detecting your SCSI HDD, please see the
SCSI HDD Troubleshooting Guide.

1. Unlike the onboard IDE controller, you must load the SCSI controller
driver before the operating system (OS) can use it.
2. Microsoft Windows 98 comes with default drivers for most SCSI controllers
available on the market today. But with other OS such as Microsoft Windows NT and
Novell Netware, you must manually load the SCSI driver yourself; consult
your SCSI controller user's manual for more detailed instructions.

1. You can check if your SCSI controller is detected by your system
board by looking for the SCSI controller BIOS message. Most SCSI controllers
allow you to go into the SCSI BIOS setup by pressing a specific keyboard
combination. For example, you can get into most Adaptec SCSI controller BIOS
by hitting control-A.
2. If you do not see the SCSI controller BIOS message, then you may
have a defective controller. Try the controller on a different system and
see if it works.
1. Unless you're running Windows 98, you'd have to manually load the
SCSI driver for your specific operating system. Consult your SCSI controller
user's manual for more details.
2. If you have an Adaptec SCSI controller, click
here for the drivers.
