xenthar Unfortunately ALL p!!! processors

xenthar Unfortunately ALL p!!! processors with ANY BIOS on LX-based motherboard DON'T WORK under W2K/XP. NT4/W9x/*NIX work fine. I run Linux, W98, and NT4 sp6 on ASUS P2L97s and P!!! 600 (katmai) downto 400, also on celeron 566 and celeron 733, but i can't install W2K and XP. AFAIK it's impossible.
About microcodes. First way - try find 2Mbit EEPROM and 2MBit BIOS version for youre motherboard. Patcher insert ALL microcodes in this case. Enother way - free space in original 1MBit BIOS manualy, then try patch it again.
