If it does, then edit /etc/modules.conf and add the following line:
options agpgart agp_try_unsupported=1
Close down any open X applications, then type Ctrl-Alt-F2 to switch to virtual console 2, log in as root, then shut down X with the following command (if you use graphical logins):
# init 3
Once X is shut down, type the following commands into the console:
# /sbin/modprobe -r agpgart
# /sbin/modprobe agpgart
Check your dmesg for lines like this:
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected an Intel i845 Chipset.
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: AGP aperture is 64M @ 0xec000000
If you get those lines, the AGP GART driver found your AGP bridge. Restart X by typing:
# init 5 && logout
You may need to edit your XF86Config to use the proper drivers once you get agpgart working.
Unfortunately this is what I get:
[root@master jbshultz]# modprobe agpgart
/lib/modules/2.4.21-0.25mdk/kernel/drivers/char/agp/agpgart.o.gz: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.21-0.25mdk/kernel/drivers/char/agp/agpgart.o.gz failed
modprobe: insmod agpgart failed
As can sort of be seen from above, I do have a file agpgart.o.gz in the right place.
When I exit X (I boot up in init3) there are a bunch of errors that indicate that, quite simply, this thing isn't finding the AGP port.
