The BIOS on that page appears to be the answer to your problem. You will need to determine which of the two (the 246K or 239K) is the correct one for your machine. Once you have done that, go to www.bootdisk.com and get the BIOS flash DOS bootdisk image. Then unzip the files to the DOS bootdisk.
made a me disc as my laptops got me on it - got the bios code tried clicking on it when it was on my desktop and it went into dos mode doing unzip and saying everything was ok then tried to do xp update and when it gets ready to install it comes back with message saying not acpi compliant.
clicked on the Phlash thing and it came up with bios rom error
tried this from boot disk and get same bios rom error
A WinMe bootdisk has excess baggage that isn't wanted for BIOS flashing. Click on the above link and get the DR DOS bootdisk image, and use it to format a floppy. Since you do not seem to have any other way of determining which of the two offered your laptop needs, try each of the BIOS. One of them will work. Unzip the files to the DR DOS floppy, and boot from the floppy. If you get a BIOS ROM error, try the other BIOS file (you'll have to exit the utility and restart it).
