This is normal behaviour. You can use manually patched BIOS (by BIOS Patcher) or flash rt_6btm.bin in another EEPROM (as I remember this version of BIOS works normally with Winbond 29xxxx, but NOT with Macronix EEPROM's) Note that on 6BTM default EEPROM is from Macronix

Could you try test your computer with another videocard (better if it will be PCI-video)?
