DJGPP + backplane + PCI + interrupts

  1. We are trying to use PCI backplane with multiple PCI cards including USB
    card. The embedded processor is X86 with DOS and 32 bit extension
    (DPMI). The PCI cards are producing shared interrupts and we are having
    problems of different types, which we suspect are either in our driver
    software or in the hardware (PCI cards) including the transparent chips
    in the backplane. We would appreciate if someone with experience in a
    similar system can advise us or act as a consultant.
