Using SCSI Drives as C and D
Make sure your computer's CMOS Setup program is set to No
Drives Installed.
The drive with the lowest SCSI ID is automatically used for
boot-up. Refer to the disk drive manual to learn how to set the
drive's SCSI ID. You can also use SCSISelect to specify the boot-
up drive; see page 3-18.
Always turn the computer's power
any values on a channel, in a Setup program, or on a SCSI
device. This ensures that the new initial values are loaded.
Make sure SCSI Parity Checking is consistently enabled or dis-
abled on all devices on the SCSI bus.
Verify that the channel and the SCSI devices are properly con-
figured and installed.
Check that the SCSI bus is properly terminated.
Check that the disk is formatted and has a DOS partition. If the
disk has not been formatted, run the Format Disk utility
included in SCSISelect. See SCSI Disk Utilities on page 3-18.
Computer Hangs, or Channel Cannot Find the Drives
Check SCSI parity for consistency
Check for correct SCSI termination on each device.
Check cable length and integrity. Check pin-1 orientation.
If the host adapter LED stays on when the computer hangs, the
host adapter might be interfering with your computer's opera-
tion. Is the adapter installed in a PCI slot that does not support
bus mastering? See your computer documentation.
