I'm currently trying to get a Promise Ultra/33 to work with Sørens new ata

This is with a -current from about three days ago.
Unfortunatly, I don't understand enought about the new bus stuff to really
understand where the null pointer gets into the game.
Ah, if it matters: the Promise currently has the EPROM removed.
Any hints appreciated,
Stefan
