Hi,
 
Been testing DJGPP (v1.11.maint2) for a while and it looks great!
32bit flat memory model and everything... but it seems that you cannot
access *directly* the first 1Meg (mapped at E0000000) while running
QEMM's QDPMI or VDM under OS/2 (ie. DPMI in use) ?
 
Since it would be great to be able make same C/ASM sources to
work in OS2 and DOS. What I especially need is the ability to use virtually
same 32bit assembler routines that access video memory (text/graphics) 
under both operating systems.
