Re: PCI BRIDGE transparency???
Hi List Members,
I would like to write a source code in assembly language to access an
internal modern PCI compliant Modem - Motorola or US robotics, plug
into a PCI slot of a ASUS mother board, with Pentuim III, 600Mhz CPU.
My question is:
Will the instruction sets of the Pentuin CPU,in particular IN and OUT
insructions, addressing the COM port reaches the target PCI device at
the other side of the bridge as if the bridge is transparent? Or are the
and the address contents released by the Processor on the host PCI
bus the same data and address contents on the local PCI bus.?
Is there any one who had tried doing what I would like to do? Perhaps
he access maybe the in C++.
Many thanks in advance.
Best regards to all,
Marcial de Guzman
