Hi everyone,
i have just finish implementing a Slave PCI on a FPGA board with PCI interface. And this core seems work fine. Work fine means the OS can find the new hardware component and ask for the driver, also can read / write data by using WinDriver. But when i plug this card onto the motherboard which is with on-board lan card. The OS can't discover this new hardware and the original on-board lan card on the mothercard has disappeared(it don't show up in the software). However, my core do not have problem in every motherboard without on-board lan card. I find it very strange and i don't know why. Can anyone give me a hand? Is it the PCIBIOS on different motherboard has difference in configurating the device? Or the memory range i declare in my core has exceed the range that the mother board can give to my hardware?( i just declare 256 K in my hardware). Or anything cursh in the interrpt? Thank you very much and any reply will be appreciated. Regards, TOM |

Are you using interrupts?
