Probable Cause
(for integrated MultiBay/
USDT systems)
MultiBay device not
properly seated.
or
MultiBay riser not
properly seated.
A device is attached to
SATA 1 and/or SATA 3.
Devices attached to these
connectors will be
inaccessible while "SATA
Emulation" is set to
"Combined IDE
Controller" in Computer
Setup.
One or more SATA
devices are improperly
attached. For optimal
performance, the SATA 0
and SATA 1 connectors
must be used before
SATA 2 and SATA 3.
Processor not supported
by ROM BIOS.
The previously saved
copy of the MBR has
been corrupted.
The current MBR does not
match the previously
saved copy of the MBR.
376220-001
Recommended Action
Ensure the MultiBay device is fully
inserted.
Ensure the MultiBay riser is properly
seated.
If using Windows 2000 or Windows XP,
change "SATA Emulation" to "Separate
IDE Controller" in Computer Setup.
If not using Windows 2000 or Windows
XP, relocate the affected devices to SATA
0 or SATA 2 (if available).
Remove the affected devices from SATA
1 and SATA 3.
Ensure SATA connectors are used in
ascending order. For one device, use
SATA 0. For two devices, use SATA 0
and SATA 1. For three devices, use SATA
0, SATA1, and SATA 2.
Upgrade BIOS to proper version.
Change the processor.
Run Computer Setup and save the MBR
of the current bootable disk.
Use extreme caution, The MBR may have
been updated due to normal disk
maintenance activities (disk manager,
fdisk, or format).
Ä
Replacing the previously saved MBR
in such situations can cause data
loss.
If certain that the MBR change is
unintentional and undesired (e.g. due to
a virus), run Computer Setup and restore
the previously saved MBR copy.
Otherwise, run Computer Setup and
either disable MBR security or save the
MBR of the current bootable disk.
