[Coco] Multiple HDB-DOS 256 drive partitions Software Wanted

[Boisy Pitre]

Luis,

SuperDriver does allow for multiple partitions on the same device by using the WPC byte and OFFS word in the device descriptor as a 24 bit offset from the beginning of the drive. That value is added to every sector passed to I$Read and I$Write.


Merci,
Boisy
