Hi !

	We got an old IBM AT (6 mhz) that does not support 1.44 3.5
inch drives.  It has a DTC 5287 RLL controller.

	My question is twofold, to to get into the DTC ROM menu,
we need to use debug, can someone provide the starting address 
of the DTC card to do low level format as we lost the documentation
for it.

	Secondly, is there any drivers out there that will let
the AT support the 3.5 inch and it does not recongize a 3.5
inch in setup.

	Thank you.
