System Boot
Does not boot from the expected boot device
Reason
Solution
Boot device order is not correctly set.
Change the boot device order in the BIOS. See
Chapter 7.
Operating system is not on the system
drive.
Reinstall the operating system.
BIOS attempts to boot from wrong hard
disk drive.
Ensure SCSI controller for primary system disk
drive is installed lower in slot order than any other
SCSI controllers.
IDE hard disk drive is connected to IDE
controller.
BIOS cannot boot from SCSI hard disk drive if an
IDE hard disk drive is connected. Disconnect all
IDE hard disk drives.
System attempts to boot from CD-ROM
drive instead of a SCSI hard disk drive.
Do not boot the system with a bootable CD-ROM
disc in the CD-ROM drive. You may want to
change the boot device order in the BIOS to boot
from a SCSI disk drive first. See Chapter 7.
