1.BIOS:
We are sorry. You can not update the BIOS (EPROM) for your motherboard due to the chip used at that period of time. Please try contacting our dealer or distributor that near you for assistance.
This is what their website saying.. This means that this manufacturer never ever have release a Bios update file on their website... So trying to get an rom file on the orginal website wont be the solution..
Only what would help is trying to find an second one with a working rom chip on it and clone it (and have backups for future uses) Or having lucky to proudly landing an a ROM collection website who have the right rom for you..
The board is also known as KM-S4-1, Rectron RT-4s3 . Try to find one if these roms.. Maybe they would work for you.
~ At least it can do black and white~
