AGP Bus Disabled

After installing a new drive and reinstalling XP, I noticed I was no longer able to select an AGP speed in the ATI9800 display menu. DXDIAG shows "AGP Textures are not available" and Sandra2004 shows "AGP Bus Disabled". I checked the bios (Gigabyte 8INXP) to make show AGP was enabled. Reinstalled the lasted chipset, video drivers, to no avail. I'm not sure where the problem even is; motherboard, videocard, software, etc. Tried ATI and Gigabyte newsgroups and websites. Any suggestions?

in dxdiag, click on the Display tab and check under the heading "DirectX Features" and there should be an enable/disable box next to AGP Texture Acceleration. is that not enabled?
 
ive been doing some research and found people offering the following suggestions:

1) go into the bios and adjust the agp aperture settings. try setting it really high like 256 then rebooting and setting it back to like 128 or 64 (this worked for one fellow on a forum that i found)

2) reinstall your agp drivers that come with your motherboard. somehow they may have gotten corrupted and need to be reinstalled off your mobo disk.

hopefully one of these solutions help you out 🙂 post back if they dont work.
 
The enable/disable button in the dxdiag display menu is 'blanked out' (cannot be pressed) It has the "AGP Textures are not available" message next to it.
As for the AGP drivers, that where it gets interesting. A search of the disk that came with the board, shows no AGP drivers listed. Nor can I find any on the Gigabyte support website (no reply from them), other than drivers for various video cards. As I admit to being no 'whizkid', it's possible I missed something, but I don't think I did. I don't suppose there is a generic agp driver for the Intel7205 chip. Off to try suggestion #1. And thanks for your reply.

well being that its an intel chipset you should try to update the Intel® Chipset Software Installation Utility: linky and see if that helps. your chipset is the E7205 and needs the chipset installation utility. if i were you i would get the latest version at the link ive provided and see if reinstalling this helps at all.
 
Well, this is geting interesting. I can find nothing listed as 'AGP Aperture' settings, anywhere in the bios menu's. The only thing I could find is AGP voltage and AGP frequency (that it?)

John
 
no, thats not it. it should be listed in the bios where there is a section called pci latency and video boot mode which allows you to select pci/agp based on what kind of card you have. its hard to explain because every bios is different and without it right in front of me its really a shot in the dark. if you cant find that option then try the updating of your chipset drivers to see if that helps at all at the link i provided in the previous post.
 
Followed the link you provided and downloaded and installed the infinst_enu.exe file for my chipset and OS and that did the trick. Rebooted a few times to doublecheck and everything seems to be running fine now.
Many, many thanks for your assistance. I think I have found a new home.
