hi
i have a dos program using DPMI and making PCI accesses. it runs fine as
a DOS stand alone. Under dosemu  it can make PCI configuration access no
problem. but when it tries to make PCI memory access then it fails. i am
trying to access the following PCI MMIO resource at address 0xDFFFF000:

0a:0a.0 Bridge: Device 1895:0001 (rev 01)
        Subsystem: Device 1895:0001
        Flags: bus master, medium devsel, latency 64, IRQ 10
        Memory at dffff000 (32-bit, non-prefetchable) [size=4K]
        Memory at 80000000 (32-bit, non-prefetchable) [size=1024M]
        Memory at de000000 (32-bit, non-prefetchable) [size=16M]
        Memory at dd000000 (32-bit, non-prefetchable) [size=16M]
        Memory at 7e000000 (64-bit, prefetchable) [size=16M]


is it possible to access PCI MMIO under dosemu?
thx a lot
