We recommend that you always contact the manufacturer of your SCSI controller for any available BIOS updates. SCSI controllers (and drives) reach development end-of-life. New updates may not be available. Some SCSI controllers require OEM specific versions to work with the specific chipset on the controller. This is especially true if your SCSI controller or host adapter was installed by an OEM manufacturer (such as Compaq, HP and Dell). BIOS utilities are typically updated with a manufacturer provided utility.
Before you proceed, identify your specific make, model of SCSI controller, the current BIOS revision numbers, and part number (typically printed on BIOS chip).
