Booting The Computer From A Scsi Drive; Using A Standard Drive As C And A Scsi Drive As D - Adaptec AHA-3980 User Manual

AHA-3980/3980W/3985/3985W User's Guide

Booting the Computer from a SCSI Drive

Be sure that both standard hard disks are mapped out of the
computer by setting the CMOS setup to No Drives Installed.
Be sure that the SCSI boot drive is on Channel A and has the
lowest SCSI ID on that channel. Also, verify that each device
on the channel has a unique SCSI ID. You can use SCSISelect to
determine the SCSI IDs of devices on the SCSI bus, as
described in Listing SCSI IDs on page 13-11.
Be sure that parity checking is consistently enabled or disabled
on all devices on the SCSI bus. See SCSI Parity Checking on
page 13-3.
Verify that Include in BIOS Scan is enabled for that device in
SCSISelect. See Include in BIOS Scan on page 13-5 and Changing
the AHA-398x Settings on page 13-7.
Be sure to reboot the computer after changing any values on a
channel, in a CMOS setup program, or on a SCSI device. This
ensures that the new initial values are loaded.
Be sure that the SCSI bus is properly terminated. See Terminat-
ing the SCSI Bus on page 5-12.
Be sure that the intended boot disk has an active DOS partition
and has been formatted.
Check cable connections and pin-1 orientation.

Using a Standard Drive as C and a SCSI Drive as D

Use the CMOS setup program to map the second standard
hard disk (if one exists) out of the configuration.
Be sure that the SCSI drive to be used as drive D has been
assigned SCSI ID 0 on Channel A. You can also use SCSISelect
to determine the SCSI addresses of peripherals on the SCSI
bus.
Be sure that SCSI parity checking is consistently enabled or
disabled on all devices on the SCSI bus.
Verify that the channel and the SCSI devices are properly con-
figured and installed.
