Adaptec 39106 Combining Scsi and Non-SCSI Devices, Support BBS? From Scsi drive? Then do this

Using the Adaptec SCSI Card 39160 and SCSI Devices

Combining SCSI and Non-SCSI Devices

You can install the Adaptec SCSI Card 39160 in a computer that already has a non-SCSI controller, such as an EIDE controller. How- ever, you cannot cross-connect the disk drives and other devices: SCSI devices must be connected to the Adaptec SCSI Card 39160, EIDE devices must be connected to the EIDE controller, and so on.

When you install the Adaptec SCSI Card 39160 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 Spec- ification (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 mother- board 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	Want computer to boot
support BBS?	from SCSI drive?	Then do this:
No	No	No action required. SCSI drives
		and non-SCSI drives can be used
		together.
No	Yes	Run CMOS Setup program.
		Change primary Hard Disk set-
		ting to None or No Drives
		Installed (see computer docu-
		mentation). You will not be able to
		use the non-SCSI drive(s) at all
		when you boot from the SCSI
		drive.
Yes	No	No action required. SCSI drives
		and non-SCSI drives can be used
		together.
Yes	Yes	Run CMOS Setup program and
		select SCSI drive as boot device.
		SCSI drives and non-SCSI drives
		can be used together.
