Attached photo card What does your card do? Does the PC boot without picture? Or doesnt it post at all? I receive a beep signal for no graphics card I have a 1.33 card, I tested the BIOS chip on it and it works fine. What size of EPROM do you use? 27256 There are several differences in the board …

The archive HEATH EGA.rar contains two BIOS dumps 1.32 and 1.33. But they are identical up to the byte, this is an error, or they are the same? I am trying to use this BIOS for card version 1.31, but it doesn't work. Do you have a BIOS for version 1.31? Thx
