I can't know if you need that BIOS update from IBM. Here's the text from IBM.COM that might apply, but I can't tell since you didn't reveal the make and model.
I can assure you this is not a Windows 2000 issue.
"Flash BIOS update
for IBM Aptiva 2178 and 2198 systems
This package updates the basic input/output system (BIOS) on
Aptiva(R) model 2178-xxx and 2198-xxx computers.
BIOS is programming that controls low-level hardware operations,
including interactions with diskette drives, hard disk drives,
and the keyboard. The BIOS is stored on a chip. Your computer
uses flash BIOS, which can be updated through a program on a
flash diskette so that you do not have to replace the BIOS
chip to update the BIOS.
Note: Make note of any settings you have changed in the BIOS
Configuration Utility. These settings may have to be re-entered
after updating the BIOS.

Downloading the update
1. Click the file link to download the file from the web page.
2. When prompted, select a drive and directory in which to save
the downloaded file.
Extracting the update
Installing this update involves creating a BIOS flash diskette and
running the flash program from the diskette. Before you begin,
have a blank 1.44 MB diskette ready.
1. Click Start, highlight Find, then click Files and Folders.
2. Insert a blank 1.44MB floppy diskette into the diskette drive.
3. Type pjjt38a.exe in the search box, then click Find Now. This
will locate the pjjt38a.exe file you just downloaded.
4. Double-click the icon for pjjt38a.exe.
5. Follow the onscreen prompts. The necessary files will be
extracted to the diskette.
Installing the update
1. Close all open applications.
2. Leave the diskette in the A: drive, and shut down and restart
the computer to start the BIOS flash program. You will be
prompted with the following message:
Press Enter to continue.
Press ESC to cancel.
3. Press Enter. You will be prompted with the following message:
0 = Quit
1 = Flash BIOS
2 = Update Serial and Model Numbers
Select Choice (0-2):
4. Press 1.
5. Press Enter.
6. Wait until you see a message stating
* POST/BIOS update was successful. *
* Press ESC key to restart the system. *
7. Remove the diskette from the diskette drive.
8. Press ESC.
PJJT31A is the flash diskette level.
PJKT31A is the BIOS binary image level.
NOTE: All changes carry forward. That is, if a change is added
in 01, it is also in 02, 03 etc.

prevents a potential data error problem. Although Intel
states that the problem can only occur under certain limited
temperature and voltage conditions, IBM strongly recommends
updating your BIOS immediately.

code without updating their current level of BIOS, please
refer to the "README.1ST" file.

450 Mhz Processor
After inserting a new system memory -which has worked for several days, fine- I recieved this message:
184 asset control antenna not detected
176 the system has been tampered with
turn power to your system off and the on
your system is locked
How do I fix this, wothout losing data?
