Adaptec SCSI Card 19160 User's Reference Combining SCSI and Non-SCSI Devices You can install the Adaptec SCSI Card 19160 in a computer that already has a non-SCSI controller, such as an EIDE controller. However, you cannot cross-connect the disk drives and other devices: SCSI devices must be connected to the Adaptec SCSI Card 19160, EIDE devices must be connected to the EIDE controller, and so on. When you install the Adaptec SCSI Card 19160 and SCSI disk drives in a computer that boots from a non-SCSI disk drive, the computer will continue to boot from the non-SCSI disk drive unless you change the computer's CMOS configuration. You do not need to change the configuration if you just want to use the SCSI drives for additional file storage space. If your computer's motherboard BIOS supports the BIOS Boot Specification (BBS) feature, you can select a different boot device without much difficulty. (To determine if the motherboard BIOS supports BBS, read the computer documentation or contact your motherboard manufacturer.)

Adaptec SCSI Card 19160 User’s Reference
Combining SCSI and Non-SCSI Devices
You can install the Adaptec SCSI Card 19160 in a computer that
already has a non-SCSI controller, such as an EIDE controller.
However, you cannot cross-connect the disk drives and other
devices: SCSI devices must be connected to the Adaptec SCSI Card
19160, EIDE devices must be connected to the EIDE controller, and
so on.
When you install the Adaptec SCSI Card 19160 and SCSI disk drives
in a computer that boots from a non-SCSI disk drive, the computer
will continue to boot from the non-SCSI disk drive unless you
change the computer’s CMOS configuration. You do not need to
change the configuration if you just want to use the SCSI drives for
additional file storage space.
If your computer’s motherboard BIOS supports the BIOS Boot
Specification (BBS) feature, you can select a different boot device
without much difficulty. (To determine if the motherboard BIOS
supports BBS, read the computer documentation or contact your
motherboard manufacturer.)
The following table shows what to do, after you physically install
the SCSI card and SCSI devices, to use different kinds of disk drives
in the same computer:
Does computer
BIOS support
BBS?
Want computer
to boot from
SCSI drive?
Then do this:
No
No
No action required. SCSI drives and
non-SCSI drives can be used

You will not

all
when you boot from the SCSI
drive.

Run CMOS Setup program and
select SCSI drive as boot device.
