Hi there,
while restoring my Compaq P3 i had some interesting thoughts.
First of all, this machine got an IDE->CF-adapter in the drive bay. Second, a Gotek.
But i didn't want to use Ontrack, so i checked what the 2 empty ROM-sockets are doing.
Turned out they are mapped at E000h. The Bios unfortunately only checks from C000 - DF80h for extension roms.
So i patched the BIOS to scan up to EF80h and removed its CRC-routine to make things easiert. Split XTIDE-Bios in Lo/Hi,
burned and voilá! Works like a charm. 😀
Now i'll get a ATBus expansion box and fiddle out the pinout of the internal connectors. Next plan is to change the built-in CGA-gpu to something
newer, maybe Trident. Hopefully all needed Pins are present.
Anyway, if anyone is interested in the patched bios, let me know!
Kind regards!
