Recently got Biostar P4M900-M4. Without a bios update, it didn't want to get Win 7 x32 at all and Win XP with the external video card (BSOD). After the update seems like everything is ok. Works with P4/512/800/2800Mhz. Video card - Nvidia FX3800, 1GB. RAM - 3GB DDR2. Even plays 720p video on youtube …
