If your BIOS has the big hard disk bug you can sometimes patch it. You will need to use Google Translate on the rom.by website (from Russian to whatever language you prefer), find the latest BIOS for your computer, use the autopatcher to patch it, and then flash it. Keep in mind there is a bypass key that lets you load unmodified BIOS even after you patched it. Find which key that is in case something doesn't go right.
