Thanks all! I knew you guys would have the answer. Heres an extract from the doc Ggn recommended:
-------
There are two differences between TOS and DOS disks that cause DOS to not
read the disks:
1. The Media Descriptor Byte in the Bootsector (Offset 15h) and in the first
Byte of the two FATs of the Disk is not written correctly by TOS.
It should be F8h for 1-sided and F9h for 2-sided floppies.
2. The Jump instruction in the first three bytes of the Bootsector differs be-
tween TOS and DOS (naturally - different Processor).
For DOS it should be EB 3C 90.
