Is there a new BIOS available for my system? Should I
update?
Unless there is some problem you are trying to fix,
NEC CSD does not recommend BIOS upgrades.
Upgrades are released to either fix problems or add features.
If you are experiencing no problems and aren't aware of any
features you need, you may not want to update because of the
possibility that a BIOS upgrade could change something for
the worse. It is usually best to take a look at the release notes
that are included with the computer or BIOS update and make
your decision from there on whether to upgrade.
! CAUTION
When in doubt, call the NEC CSD Technical
Support Center before updating the BIOS.
You might have to download the updated BIOS and then run
it to decompress the files, or make a diskette (the file will
instruct you).
BIOS updates are available from the NEC CSD website,
FTP site, and Bulletin Board System (BBS). Call the
NEC CSD Technical Support Center for information on
obtaining the latest BIOS for your system.
Note:
See Chapter 6 in this guide for
information on accessing the NEC CSD website,
FTP site, and BBS or for information on obtaining
service and support from the NEC CSD
Technical Support Center.
