 12 Dec 2006 3:23 problem with pci card |
|

hi all,
I design a pci card with xilinx fpga apartan2 and the pci logic was design by myself.
when test,i plug the card into the pci slot on a pc. After power up, windows says a
new hardware was found. i find in the registry that the new card's device id and vendor id were exactly what i defined in the design.
But, when i changed the card to another two PCs,it failed.
After power up, there was't any bios information on the display and just kept black.
it seems that the bios test was failed,but i'm not sure.
Can anybody give me some suggestion? thanks!

1. Check whether all PC's OS, Configuration like processor and speed are same.
2. Insert again in the first PC to check CARD is Ok or Not.
3. In the initial, each BIOS will detect the card in different way.
Say, the IRQ assigned for your card if assigned for video card then bios will get a error.
So check IRQ settings of the card also.

thank you for you suggestion!
1.The first pc is like this: Intel Pentium3 1Ghz Intel mainboard Windows xp
The second one is : Intel Pentium3 650Hz VIA mainboard Linux 2.4.20
The third one is : Intel Pentium4 1.7GHz Intel mainboard Windows 2k
2.Insert again in the first PC and it works OK.BUT the other two are still can't work.
3.The IRQ of the PCI card is assigned by BIOS and I think the BIOS will do proper assignment to avoid IRQ conflict between different cards.
Besides, I have probe the critical signals of PCI using a Logic Analyzer.
Power up the second PC and the Logic Analyzer can not probe proper configuration
read or write according to the PCI Specification.
