Now the interesting question: How did you get this running with PCem...? And how did you find out about the int21? I made minor changes to the old (ver 12) PCem source code and recompile it with mingw32. Most edits in mem.c : uint8_t romext[65536]; // was 32768 static void mem_load_xtide_bios() { …

Borland Delphi 1.0? Unfortunately, it uses "standard mode" and does not work in "real mode", so Win16 applications don't run in 8088 machines 😢

AFAIK, CGA and MDA/Hercules dosn't have own BIOS. All needed functions build in system BIOS. So, in the EEPROM is a font. You can take any from any CGA card.
