This utility will allow the modification or display of the PCI latency timer of an AGP card if it's located at device 0, bus 1, function 0. This information can be verified by using Sisoft Sandra and looking at the PCI, AGP, Cardbus buses option then clicking on the AGP bus. If your AGP video card is not device 0, bus 1, function 0 on the AGP bus I'd like to hear about it. Probably the best use for this utility is in reducing the PCI latency timer for your AGP card.
