Boot Devices
The BIOS Setup utility allows you to define the boot device location as:
•
Onboard SCSI controller
•
PCI expansion slot (default)
•
ISA expansion slot
The BIOS assigns addresses beginning at the first available address

the lower the
address, the higher the priority assigned to that device.
Server Boot Sequence
The server boot sequence is as follows:
1. If the CD-ROM drive is listed as the first boot device in the BIOS, the server
boots from the CD-ROM drive.
2. If a bootable CD-ROM is not present, the operating system can boot from either
the diskette drive (drive A) or the hard drive (drive C) using the BIOS Setup utility
as follows:
a. If the diskette drive (drive A) is selected first and then the hard drive
(drive C), the server searches the diskette drive (drive A) first to
boot the operating system. If a diskette is not present in the diskette
drive (drive A), the server attempts to boot from the hard drive (drive
C).
b. If the hard drive (drive C) is selected first and then the diskette drive
(drive A), the server searches the hard drive (drive C) first to boot
the operating system. If the hard drive (drive C) does not contain
the boot information, the server attempts to boot from the diskette
drive (drive A).
The hard drive (drive C) can be attached to the onboard SCSI controller, an ISA
expansion board, or a PCI expansion board.
The location of the hard drive (drive C) is determined by the server scan sequence
described next.
