If the machine does not boot from the floppy disk, you may need to change the boot
sequence in the BIOS to A,C,CDROM.
External Boot Devices
Most CD-ROM drives are supported. If problems arise when booting from the CD-
ROM drive, try booting CD 2 of the CD set.
If the system does not have a CD-ROM or floppy disk, it is still possible that an external
CD-ROM, connected with USB, FireWire, or SCSI, can be used to boot the system.
This depends largely on the interaction of the BIOS and the hardware used. Sometimes
a BIOS update may help if you encounter problems.
51.2.4 Booting from Installation Media Fails
There are two possible reasons for a machine not to boot for installation:
CD or DVD-ROM Drive Unable to Read the Boot Image
Your CD-ROM drive might not be able to read the boot image on CD 1. In this
case, use CD 2 to boot the system. CD 2 contains a conventional 2.88 MB boot
image that can be read even by unsupported drives and allows you to perform the
installation over the network as described in Chapter 4, Remote Installation
(page 47).
Incorrect Boot Sequence in BIOS
The BIOS boot sequence must have CD-ROM set as the first entry for booting.
Otherwise the machine would try to boot from another medium, typically the hard
disk. Guidance for changing the BIOS boot sequence can be found the documenta-
tion provided with your motherboard or in the following paragraphs.
The BIOS is the software that enables the very basic functions of a computer. Mother-
board vendors provide a BIOS specifically made for their hardware. Normally, the
BIOS setup can only be accessed at a specific time—when the machine is booting.
During this initialization phase, the machine performs a number of diagnostic hardware
tests. One of them is a memory check, indicated by a memory counter. When the counter
