PCI to PCI bridges...

[Cemre]

i have a problem... my pci hardware is as follows...

there is a main "cpu to pci" bridge, and some cards on that bridge... and an additional "pci to pci" bridge and one network card on that ( second level ) bridge.

CPU
--CPU2PCI
----CARD1
----CARD2
----CPUTOPCI
------NETWORKCARD
----CARD3



question is: do i have to enable ( in some way ) this "pci to pci" bridge to use the network card? i CAN detect the nic using PCI configuration registers, but it doesn't seem to be triggering any interupt. ( i did everything to configure the card ).

looking up for information ...
pericom.com/pdf/datasheets/PI7c8150.pdf might help (config registers in section 14)

i'd say that you should at least check the IO enable bit in the control register (maybe the BIOS enables it for you, maybe it doesn't)

oh, and just to make sure ... you of course enabled the IRQ line of the device on your PIC, didn't you ?
