Computer Will Not Boot from a SCSI Disk Drive
If both SCSI and non-SCSI disk drives are installed in
your computer, the non-SCSI drive is always the boot
device. If the computer has only SCSI disk drives,
check the following:
1
Make sure your computer’s CMOS
Setup
is set to
No Drives Installed.
2
Make sure the boot partition of the boot hard disk
is active. (The SCSI ID is usually set with jumpers
or switches on the drive.)
3
Partition the disk. Follow the instructions in the
documentation for the operating system you are
using.
If this does not solve the problem, see the trouble-
shooting information in the User’s Guide. As a last
resort, back up all data on the SCSI hard disk and per-
form a low-level format with the SCSISelect Format
Disk
option.
