Hi
I am trying to repair 286 motherboard HT12 rev 1.10. It is something like this: https://theretroweb.com/motherboards/s/iqs-jli
When I am trying to turn it on I see on my POST card "----". Second try: there are some codes and it stops on "0080", later after maybe 20 seconds next codes are blinking and it stops on "FF7F" and then after next maybe 20 seconds it is comming back to "0080". I don't know if there is right BIOS - my programmer don't want to burn 27c256 or I don't know how to do it (I have other chips, UV lamp to erase them and willem Ezo).
Please help me with this board.
