Sorry and at the ssame time happy to her that your computer is booting OK.. Your bios has to be modded manualy, plus to cut the EPA Logo, in wich I'm not that expirienced. I've only added an ISA module containong the SLIC, which obvosly dont work. Maybe someone else can try to mod it for you.
Sorry to hear that... Although I'm bufeld as well...flash under windows went well, while flash from DOS bricks the board. I will send you a PM with guides on how to recover your bios.
