Troubleshooting in Windows NT 4.0
Windows NT by default is not set up to detect cards automatically
when they are added to a system. Because of this it will be
necessary to add the driver manually. In order to add or remove a
SCSI driver controller in Windows NT, you must be logged on as
the Administrator.
What if I can't load the driver?
If the driver is failing to load, then be sure you are using the latest
version available from the Adaptec Web site at
If you are using the latest version of the driver and are still having
difficulties, then see
Common Error Messages
Here is what you should do if the following messages appear on
the screen at bootup:
"Device connected, but not ready"
The host computer received no answer when it requested data
from an installed SCSI device.
1 Run SCSISelect and set the Send Start Unit Command to Yes for
the particular SCSI device ID. See
page 3-3.
2 Ensure that the device is set to spin up when the power is
switched on. The spin up option is typically set by a jumper.
(See the documentation for the device.)
"Start unit request failed"
This message can appear if the option to send Start Unit Command
is set to Yes and device is not a disk drive. If this is the case, then
change the setting to No in SCSISelect for the device.
The SCSI card BIOS was unable to send a Start Unit Command to
one of the installed SCSI devices. Run SCSISelect and disable the
Send Start Unit Command for the device.
