3.Slot 8 is reserved for an external SCSI connector attached to onboard SCSI channel B.
4.All hard drives that are connected to onboard SCSI channels must be set for SCSI address
and “start unit command” support (spindle start on command).
5.For models with system BIOS at version 1.00.08AM0 or earlier, the BIOS memory address is
C0000-C7FFF and the video BIOS uses memory address E0000-E7FFF.
