Adaptec does provide BIOS updates for the add-in cards that it sells. For the on-motherboard chips, you'll have to contact the motherboard vendor for a BIOS update since the Adaptec and System BIOS images are usually combined. BIOS updates are rarely for fixing runtime problems. The Adaptec SCSI chips do not use a traditional microprocessor and firmware image, so it's not as if updating the BIOS will give you a new firmware that will make the chip run differently, like with an LSI SCSI chip or a RAID card. At best, the BIOS might set initial state of the chip to enable/disable/tweak certain features. The OS driver is what really controls the runtime operation, though. Scott
