SYMPTOMS
A computer that can boot from the CD-ROM drive may not be able to boot
from the Windows NT 4.0 CD-ROM.
CAUSE
A computer can boot from the Windows NT CD-ROM only if both the SCSI BIOS
and the system BIOS support the El Torito specification. Computers that do
not successfully boot from the Windows NT CD-ROM either do not support the
specification or do not support it fully.
There are three ways to support the El Torito specification: Emulating a
floppy disk, emulating a hard disk, or using no emulation. Windows NT
requires using no emulation.
RESOLUTION
Some computers have a configuration tool that permits you to choose the
boot order among the floppy disk drive, hard disk, or CD-ROM drive. If
your computer has a configurable boot order, verify that the CD-ROM drive
is first in the sequence, and set to No Emulation.
If your computer is not configurable, or does not adhere to the El Torito
specification, contact your computer's manufacturer for information
concerning an upgrade.
