LSI Logic recommends that you back up all data before making any
changes or installing any software, including LSI Logic SCSI controllers
and software. Failure to adhere to this accepted computer practice may
lead to loss of data. You must terminate both ends of the SCSI bus.
Refer to the hardware manuals for the devices and users’ guides for the
host adapters to properly terminate the bus. Also you should locate
where jumpers or 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). Refer to
for additional information
regarding the BBS.
The red or blue line on a standard SCSI cable (or the black line on one
end of a multicolored SCSI cable) designates pin 1 on the cable
connector and must connect to pin 1 on the device and host adapter
connector. Refer to the hardware manuals for the devices and the
controller to locate pin 1 of the connector.
If the system already has an internal bootable hard drive (IDE, ESDI, or
ST506), the drivers for the SCSI device(s) must reside on the internal
bootable drive.
