AGP problems... no solution found =/
Ok guys, i browsed the forums alot and found serveral ppl who had the same problem as i do, but nobody found a solution... (http://www.nvnews.net/vbulletin/show...threadid=15620 for example)
I think this could also be the reason for the performance loss many ppl talked about....
First i did not notice it either, but i saw that my performance was not as good as usual and i started to wonder... Then i tested the proc infos and saw it...
I cant get my AGP to work and i really tried everything.
The proc output is always the same...
[chris@****up(pts/1):chris]$ cat /proc/driver/nvidia/agp/status
I tried it with agpgart in the kernel and "3" as option in the XF86Config-4 file, and with another kernel without agpgart and the nvagp ("1" in config...).... no AGP support at all.
I also tried building agpart as module etcetc...
If i use agpgart, i receive the following error @ booting (dmesg | grep agp):
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo Pro KT400 chipset
agpgart: unable to determine aperture size.
If i use nvagp, i receive the following error in my XFree86.0.log (cat XFree86.0.log | grep AGP):
(**) NVIDIA(0): Option "NvAGP" "1"
(**) NVIDIA(0): Use of NVIDIA internal AGP requested
(II) NVIDIA(0): NVIDIA GPU detected as: GeForce4 Ti 4200 with AGP8X
(WW) NVIDIA(0): Failed to verify AGP usage
Ah, and i tried some parameters for the nvidia module:
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 NVreg_ReqAGPRate=8
Of course it tried it with and without those parameters...
To make it short -> No AGP support at all and no way for me to turn it on -> huge performance loss.
I'd be happy if even agp 4x would work, it does not need to be 8x (since the difference is not big, it doesnt matter..)
And i really want this to be solved, because it sucks if i have to boot windows if i want to play some games from time to time...
If you find a way to solve this problem, you would help me and probably some others alot.
Oh well, i should tell some information about my system:
CPU: 2100+ Athlon
Board: MSI (dont know the exact product name, i'll check, if it's important for you)
Gxf card: Geforce 4 TI 4200 128MB 8x AGP (MSI)
Using the latest driver installer from nvidia.com
Thanks if you try to help me.

is it a ali or via chipset?
as root type modinfo nvidia youll notice some options to enable either the ali or via agp you can also put in /etc/modules.conf:
options nvidia NVreg_EnableVia4x 1
options nvidia NVreg_EnableALiAGP 1
hope that fixed it

I have a ASUS P48SX (SIS 648 chipset) and have the same problem. I have found that the gentoo aa-sources (2.4.22-pre7) allow agp to work properly.

Not that this helps any, but I am running mandrake 9.2 beta2 and i get
[root@***** driver]# cat /proc/driver/nvidia/agp/status
AGP Rate: 8x
Fast Writes: Disabled
Maybe if you get the cooker kernel source and rebuild it, and install, it may solve the problem.
