Hello,

after finishing my 5150 build i have problems getting this thing to boot anything.
My XTIDE is not working, my BIOS-Controllers (ST21/22 + an XT-8bit-MFM) are just hanging in POST.
XTIDE throws an error 20h while booting. The card is working in other computers perfectly.

Landmark ROM states that the Keyboard Controller failed and the Floppy Read.

I checked every part, everything is clean and should be connected.

Any ideas where to look for?
