After having Supersoft running without errors on CGA, it was quite difficult to make it boot with a normal BIOS. The CGA card didnt work at all, and the board was quite picky about the VGA. An ET4000 did it. In between C22 beneath the power supply exploded, but it also runs without it.
Regarding the BIOS I tried many. TURBO XT BIOS and mony others dont display anything on all cards. Award complains about parity and doesnt let me continue. Phoenix finally works! Dont have the sockets to install the parity, but it works without, too.
Think a main problem is, that the DIP settings dont change in Supersoft when switching. So the BIOS thinks all the time a MDA is installed. The DIP seems to be specific for this board.
On-board floppy also seems to run. The 8-bit IDE interface is not compatible, so I used XT-IDE with a 16-bit controller.
And still interested in the original BIOS 😉
