Hi all,

we have designed an ISA board, that work OK in a 486 mainboard, now,
only pentium or P2 mainboard could be found in the market and we have a
big problem

the pentium mainboard that we choose, have ISA and PIC slots (typical)
the ISA to PCI bridge controller seams that is not working in
transparent mode, I mean, all the interrupts signals that come from the
ISA bus are not going to the interrupt controller (old 8059) and then to
the CPU

the interrupts used by our ISA board are fixed (I know we must change
this in the future)

we try to obtain information about this controller and we found info
about the registers and more or lest how the IRQ re-mapping work, but we
do not have any idea about how to access to a PCI slave peripherical

we are very apreciate if someone could give as any information about how
this PCI controllers work and how to access then or know about the
address range that it uses

thanks a lot in advance
