4.5.2 Start unit request failed The BIOS was unable to send a Start Unit Command to the device. Run the SCSISelect utility and disable Send Start Unit Command for the device. Time-out failure during SCSI Inquiry command! or Time-out failure during SCSI Test Unit Ready command! or Time-out failure during Start Unit command! An unexpected time-out occurred. Check SCSI bus termination. Try disconnecting the SCSI peripheral cables from the SCSI controller and then starting the computer. If the computer successfully restarts, check SCSI bus termination and cable connections. One of the devices on the SCSI bus may be defective. 4.5.3 Disk Drive Configuration Problems This section describes situations that may occur if your computer has multiple disk drives, including combinations of standard disk drives and SCSI disk drives. "Standard disk drive" means a disk drive attached to the computer through a standard ISA/EISA, non-SCSI disk controller-for example, an IDE drive. Standard hard disk drives can be set to the installed or not installed state by the Setup program supplied with the host computer. The Setup program allows you to select the number of standard hard disks that are recognized by the computer, regardless of whether they are physically installed. SCSI drives are not controlled through the Setup program. If both SCSI and non-SCSI disk drives are installed, then the non-SCSI disk drive is always the boot device.

Disk Drive Configuration Problems
This section describes situations that may occur if your computer has multiple disk
drives, including combinations of standard disk drives and SCSI disk drives.
“Standard disk drive” means a disk drive
attached to the computer through a standard
ISA/EISA, non-SCSI disk controller—for
example, an IDE drive.
Standard hard disk drives can be set to the
installed
or
not installed
state by the
Setup
program supplied with the host computer. The
Setup
program allows you
to select the number of standard hard disks that are recognized by the computer,
regardless of whether they are physically installed. SCSI drives are not controlled
through the
Setup
program.
If both SCSI and non-SCSI disk drives are installed, then the non-SCSI disk drive is
always
the boot device.
