Troubleshooting Without Diagnostics

If you encounter SCSI device problems, see the common causes and 
solutions listed in the following table.

System with UATA and 
SCSI drives will not boot 
from SCSI hard drive.

A UATA drive is 
attached, the IDE 
controller is enabled, 
and the Integrated IDE 
controller is listed 
before the SCSI 
adapter in Setup’s 
Storage > Controller 
Order menu.

Under Computer Setup, select 
Storage > Controller Order, and 
move the Integrated IDE controller 
to the end of the list.

System without a UATA 
drive will not boot from a 
SCSI drive.

The SCSI drive is not 
configured correctly.

Ensure that drive cabling and 
jumpers are set correctly. To boot 
a SCSI drive, set the drive ID 
number to 0.

Hard drive boot has 
been disabled in 
Computer Setup.

Under Computer Setup, select 
Storage > Boot Order, and enable 
the Hard Drive entry.

SCSI hard drives are not 
recognized after being 
installed when running 
under Windows NT.

SCSI drivers were 
not installed on the 
system prior to the 
Windows NT 
installation.

Install the SCSI drivers on your 
system first, then install 
Windows NT.

To download SCSI drivers for your 
Compaq system, visit the Compaq 
Web site at www.compaq.com/support

For information on installing SCSI 
drivers, see Appendix E, “Installing 
SCSI Drivers for Windows NT 
Installation.”
