I am having problems booting the computer from a SCSI drive.
Make sure your host adapter is installed and configured
correctly, as described in your host adapter's User's Guide. Here
are some of the things you should check:
Note: If both SCSI and non-SCSI (e.g., IDE) disk drives
are installed, then the non-SCSI disk drive is always
the boot device.
– Be sure the Drives setting (in your computer's CMOS setup
program) that corresponds to the SCSI boot drive is set to
None or No Drives Installed, as is required for SCSI hard
disk drives. (See your computer's documentation.)
– Be sure the Host Adapter BIOS setting in the SCSISelect
utility is enabled.
– Be sure the Extended BIOS Translation feature in the
SCSISelect utility is enabled. The host adapter BIOS
automatically selects the correct translation method as
needed.
Examine the SCO UNIX mscsi file to make sure the correct
host adapter and device are specified as the boot entry. The boot
entry is the first all zero entry in the mscsi file (see Modify the
mscsi File on page 6-8 for additional information)
For SCO 3.2v4.2 based UNIX, the boot entry looks like this:
alad Sdsk
or
blad Sdsk
For SCO OpenServer 5, the boot entry looks like this:
alad Sdsk
or
blad Sdsk
Note:
Each field is separated by a tab (do not use the
spacebar to separate fields).
