I am trying to finish off a piece of code that has to
do disk I/O with interrupts 25h/26h.  I have built in support
for Compaq DOS 3.31 "big" disks and would like to quickly
incorporate support for DOS 4.0 "big" disks.  Unfortunately I
have not yet been able to get my hands on either DOS 4.0 or the
Technical Reference for 4.0.

I was hoping that someone would already know the secrets so
I could get started with the code and be ready for testing when
the DOS finally arrives.  I would be very grateful for the help.


Thanks.
