Do not perform Device Manager "Scan for Hardware Changes" while
performing a backup, otherwise the backup may fail.
The keyboard and mouse may not respond during a BIOS online update.
Once the BIOS is completely updated, keyboard/mouse functionality is
restored.
When removing the USB diskette drive from the system, use "Add/
Remove Hardware" in the Control Panel. If the USB diskette drive is not
cleanly removed, the keyboard and/or mouse may not respond. If the
keyboard and/or mouse no longer respond, remove the USB keyboard

will be restored.
When the system is connected to a UPS for planned shutdowns and
reboots, it is possible that the active PCI module and the active Power
Switch LED will switch between modules. This is due to slight timing
differences in the boot sequences and may cause a different PCI module
to be considered "primary" each time the system is power cycled.
When adding a new (i.e.. no operating system signature) hard disk drive
to the system, add the hard disk drive while the operating system is up
and running. If the new hard disk drive is introduced into the system
when the system is not at the operating system level, the PCI modules
may not duplex. If such a condition occurs, remove the new disk and
re-insert it. The disk will be recognized and the PCI modules will
duplex.

requires the following information.
