I am trying to get a diagnostic tool written for DOS to talk to a NIC chip resident in a PCI slot. (Obviously

If I boot the machine using FreeDOS, The utility recgnizes the card and all is fine. If I run the same utility under DOSBOX (0.73), it never recognizes the card.

I compiled DOSBOX with --enable-debug active. When I run the program I get the following:
122487514: BIOS:INT1A:PCI bios call 2
122487522: BIOS:INT1A:PCI bios call 2
122487530: BIOS:INT1A:PCI bios call 2
122487538: BIOS:INT1A:PCI bios call 2
122487546: BIOS:INT1A:PCI bios call 2
122487556: FILES:file open command 0 file autoexec.do

Is there something I am missing in my configuration? Are there problems if the card tries to directly access the memory of the PCI device that dosbox does not support?

Thanks
Doug Bailey

DOSBox does not communicate directly with _any_ hardware
The CPU/BIOS/Port IO/DOS Interrupts/etc are 100% fake user mode emulation
