Question: System does not boot when multiple USB
CD/DVD-ROM drives are attached to the system simultaneously.
How can I resolve this issue?
Answer: The IBM 4810-x4x BIOS only supports booting from a USB
CD/DVD-ROM drive when one USB CD/DVD-ROM drive is attached to the system.
The following configuration changes can be applied to allow the system to boot
from the desired USB CD/DVD-ROM drive:
v
Remove the unneeded USB CD/DVD-ROM drive(s) from the system. When the
desired USB CD/DVD-ROM is no longer required to be booted, all drives may be
reattached to the system. However, BIOS setup must be changed to move the
“CD-ROM” entry to appear below the “Hard Disk” entry in the BIOS setup boot
priority list.
v Move the “CD-ROM” entry in the BIOS setup boot priority list to appear below the
“Hard Disk” entry.
v Lower the USB legacy host controller connection speed to “Full/Low Speed”.
Note that this does not disable high speed USB for usage by the installed operating
system. High Speed USB is only disabled for USB legacy boot support.
