Problems Booting the System from a SCSI Drive
•
Make sure that both standard fixed disks are mapped out
of the system.
•
Make sure that the SCSI boot drive address is set to SCSI
ID 0:0. Check the drive installation manual for informa-
tion about setting the SCSI ID for that device. The
Return Installed Devices utility in the Onboard utilities
can also be used to determine the SCSI addresses of pe-
ripherals on the SCSI bus.
•
Make sure that SCSI parity is consistently enabled or dis-
abled on all devices on the SCSI bus.
•
Verify the proper installation and configuration of the
host adapter and SCSI devices.
•
Power should be cycled OFF and ON after changing any
values on a host adapter,
setup program, or SCSI device,
to be sure that a DOS format operation has been success-
fully completed.
•
Make sure that the SCSI bus is properly terminated.
•
Make sure that the intended boot disk has an active DOS
partition and a DOS format.
•
Check the cabling.
Problems Using a SCSI and a Standard Disk
Drive
The drives are configured as SCSI disk drive D and standard disk
drive C.
•
Make sure that the second standard fixed disk is mapped
out of the system.
