m Caution

Before you Continue: If the SCSI channels

embedded on the system board are controlled by a

Symbios Logic

chipset, the Symbios chips must be

disabled in the system BIOS before proceeding with

RAID configuration, operating system installation or

driver installation. This is to allow the AcceleRAID to

take over control of the system board's embedded

channels without any conflicts.

The Symbios chipset can be disabled by running the

CMOS setup routine when powering on your system

(see the documentation that is furnished with your

system).

3. Plug the AcceleRAID card into the specially prewired SISL PCI slot.

See the documentation provided with your system board to locate this

special PCI slot (see Figure 9).

☛

Note

When an AcceleRAID 150 or 250 is plugged into the

SISL PCI slot, the channel on the controller

automatically assumes the address of Channel 0. The

addresses of the channels on the system board are

pushed out by one.
