How to detect AGP card??

Hi, I want to write a AGP driver. Ive already written a PCI driver before, when I use it in VMware, it can detect 10 drivers.

Type Display, I only found "VGA" detected. I thought I hadn't detected the AGP card correctly. Or VMware doesn't support VGA card??

I don't think VMWare emulates an AGP card, try testing your OS on a PC with an AGP card installed and see what happens.

You need to hunt around for the AGP specification. The part you want is in appendix B.

I've managed to find it at this website:
