6.3 Basic Rules for SCSI Host Adapter and
Device Installation
You must terminate both ends of the SCSI bus. Refer to the hardware
manuals for the devices and the host adapter to properly terminate the
bus.
Unless your system is SCSI Configured AutoMatically (SCAM)
capable, you must configure each SCSI device with a different SCSI
ID number. Refer to the hardware manuals for the devices to locate
where the jumpers of dip switches are for setting SCSI ID numbers.
Usually, the host adapter is ID 7. The devices are then set at IDs 0
through 6 (plus 8 through 15 for Wide SCSI). The bootable hard drive
must have the lowest numerical SCSI ID, unless you are able to use
the BIOS Boot Specification (BBS).
The red or blue line on a standard SCSI cable (or the black line on one
end of a multi-colored SCSI cable) designates pin one on the cable
connector and must connect to pin one on the device or host adapter
connector. Refer to Appendix B to find Pin 1 of the connector.
6.4 Configuring the SCSI Adapter
Access the SCSI BIOS by holding down both the CTRL and C keys
when you see the BIOS banner message listing the driver name and
the attached devices. For example:
Symbios Inc. SDMS (TM) V 4.0 PCI SCSI BIOS
PCI Rev. 2.0, 2.1
Copyright 1995, 1998 Symbios Inc.
PCI-4.12.00
Press Ctrl-C to start Symbios Configuration

The SCSI Select screen will come up. Instructions on how to move the
cursor and select options are listed on the bottom of the program
windows. You can select either Configure/View Host Adapter
Settings or SCSI CD Utilities.
