I am investigating the possiblity of using Openbios as a tool to verify our custom PCI designs.

Specifically what I am interested in is the ability to modify the PCI base address registers and excercise the address decoders on the cards. What I'm after is some basic PCI compliance testing that is hard to do with a full blown OS.

My problem is that I'm having a tough time with the learning curve of openbios. I'm having trouble figuring out how to do some basic things, like query the BARs of a PCI device. I'm using Qemu as a sandbox to play with openbios, but I can't even figure out how print the value of configuration register zero of a particular device!

Can anyone steer me in the right direction? Am I wasting my time, or does it sound like Openbios is going to do what I want.

Thanks,

John
