@TjLaZer:

If I recall correctly, the rom-image is 16kB large, whilst the 27C256 is 32kB. As you dont know if the GVP card will use the upper or lower 16kB part of the 27C256, burn the rom-image to both parts.

That atleast did the trick with my GVP HD8+ and HC+8.

Other than that, the software you are using must ofcourse know how to decode Intel HEX so it just doesnt burn it as raw data.

@TjLaZer:

That should do the trick.

The amount of "real data" inside that 44kB Intel HEX file is 16044Bytes. Your software should pad the rest up to 16384Bytes with 0x00 or 0xFF.


@DamageX:

All expansion card drivers will end up in the highest priority ram, which should be fastram if you have any. They are never executed from the ROM on the expansion card directly.
