Is there any way to format MFM HDD (ST-251) with this controller?
Debug with -g=c800:0 and -g=c800:5 gives invalid opcode error.

Looks like regular 16-bit MFM controller, so no BIOS extension in C800 segment.
Use the LLF option in main BIOS if available, if not - eg. HDINIT.EXE from Checkit 3.0.
Nie tylko, jak widzicie, w tym trudność, że nie zdołacie wejść na moją górę, lecz i w tym, że ja do was cały zejść nie mogę, gdyż schodząc, gubię po drodze to, co miałem donieść.

Actually that is what I did in a first place. But on cylinder 250 it failed after few minutes of loud knocking sound. That is why I was looking for alternatives.
But today I gave BIOS second chance and everything went OK.
