Hi there,

All this sounds great, but I'd like to ask you a few questions:
- Is the memory protection feature still available ?
- What about the Falcon, did you manage to make the VDI work with VM ?!
  The Falcon VDI always uses the Blitter chip, whose address bus is only 24 bits
  wide, and which doesn't use the PMMU so that it cannot access data at locations
  higher than $FFFFFF.
- How do the user sets the size of the VRAM and the amount of physical memory used
  for the frames.
- I don't understand why you did patch AHDI, mine was working perfectly under VM
  and you can set up the _FRB cookie for the ACSI transfers.

In fact, I began a MiNT VRAM implementation some months ago which is quite ready
but I didn't manage to go on the job as I didn't find the time to solve the Falcon
Blitter problem (studies...).

Regards, Eddy.
