I did (not sure wich one i used), everything worked fine, until i had to reboot. PC doesn't start up anymore, even the backup-bios does not start. I solder out the eeprom, now the backup BOS starts up but dies and the PC reboots again. Damn bricks. I plan to flash the eeprom using another MB, but this time one from an expert and not such a mess like before. Hopefully it will work ...
