SCSI Problems
This section lists some common SCSI problems to check if the system cannot
communicate with a SCSI device. When solving a SCSI problem, verify that:
o All SCSI devices are turned on before turning on the system.
o SCSI drivers are properly installed (Section F.6), the correct path is in
AUTOEXEC.BAT, and the drivers are loaded in CONFIG.SYS.
o The first device and the last device in the SCSI chain are properly
terminated (Sections F.1 and F.2).
o All SCSI devices have different SCSI IDs.
o The cables connecting the SCSI devices are properly seated. 
						

							o The internal cable connector is not reversed.
o All SCSI devices are SCSI-2 compliant.
For more troubleshooting information, refer to the system messages and
troubleshooting sections of the Compaq EZ-SCSI Software Reference.
For information on using SCSI-2 devices, installing SCSI-2 device drivers,
and installing an internal SCSI-2 drive in the Compaq SmartStation, refer
to Appendix F.
7.2 EXTDISK.SYS Error Messages 
The EXTDISK.SYS external drive device driver is required for the Compaq LTE
Lite to configure an IDE hard drive in the Compaq SmartStation. This
section lists EXTDISK.SYS error messages that may be displayed and
describes their possible causes and recommended actions.
Install the EXTDISK.SYS external drive device driver from the Supplemental
Programs diskette included with the SmartStation Adapter (Section C.4).
