BIOS UPDATE UTILITY (BUU)
The BIOS Update utility updates the ROM BIOS version of the system. This software util-
ity updates the Flash ROM installed on the system board. The utility identifies and saves the
currently installed BIOS version before installing the new version.
To receive the latest BUU diskette (in the U.S. only), call the Technical Support Center at
(800) 632-4525 or download the BUU by logging onto NEC's Electronic Bulletin Board
System (BBS) and perform the procedures described in the following subsections.
To use the BIOS Update utility, the system configuration must be set to 640 KB of base
memory with the programming voltage enabled.
Precautions
The BIOS Update utility diskette saves the old BIOS version. Make sure the diskette is not
write-protected. If attempting to use a diskette that has updated another unit, a message

make a copy of the original diskette for each system before using the diskette.
