S-100 IDE project

Hi!  John has some CBIOS software for CP/M 3.0 based on his system.  I do
not know what the maximum drive size is but on the N8VEM DiskIO board CBIOS
for CP/M 2.2 the maximum size is 8MB.  I believe the 8MB limit also applies
to the S-100 IDE board.  At least in theory you could implement your own
CBIOS extensions for partitions and the like.  We are doing something akin
to that on the N8VEM project for the SBC DiskIO CBIOS.  However that is a
completely separate project from this board.  

Anyone who gets one of these S-100 IDE boards would have to integrate it
into their CP/M system using the PCB, the schematics, and the example code.
No further support is offered.  As John wisely says on comp.os.cpm "Please
note these would be bare cards, a schematic and that's it. Building the
board and implementing CPM etc., you are on your own. This is not a project
for first timers."  There you have it -- Caveat Emptor.  

Thanks and have a nice day!

How are you getting around the 8meg max drive size common with CPM ?
Are you splitting it into many small drives in hardware on in the driver 
like Morows dod for the M26 ? 
I have an old MPM system that had an M26 on it I would like to bring back to
life.
