I agree. Ive tested an unmodified Xenix bootdisk with my real widget drive. That seems to be OK, because no errors.

Youre right. Ive found it, now. Thanks ! Ive just taken a look at the pictures and didnt read all yesterday

Ive done that every time.

Ive tried it with FEdit a third time, now. And Ive doen it using lisafsh-tool with the offsets changed. Ive taken the modified and the unmodified DC42 Images and took a look into them for comparing using HexEdit.
Everything seems to be allright, but in every case I get the same result (Handshake err)

Ive some other CF cards and this Card I want to use for Xenix still boots LOS2.0 very well.
Also Ive erased an other card in the XProFile with success. But booting Xenix : Same result.

At the moment I dont have any more ideas ...
