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).
