Default settings on most BIOS setups is to give preference to PCI for video. I'm assuming its a holdover from a time before AGP was popular. I've seen many new computers with onboard AGP chipsets with the BIOS set to PCI instead of AGP. Dont know why they dont bother to set that for you, when the computer is supposed to be "ready to go". I saw one a friend of mine bought once that wouldnt boot. I checked his BIOS and the darn thing hadn't detected the HD. I ran the autodetect, and it picked it up first try. Some are picky that way. I guess at HP they dont bother to check the BIOS before shipping. Of course, almost half of his 20 GB HD had bad sectors too, but thats another issue.
