i had to add the "Option NvAGP" "1" to my XF86Config-4 to get it working. q3 linux runs great on a dual p3 550, ultra tnt2 32, 2.4.18-10smp kernel(i think thats what it is) anyways i did the update from redhat wich did the kernel also. had a hell of a time figuring this out. installed from the i686smp rpm on the nvidia site.
in case anyone finds it interesting it a netserver e60, wich hp says no way for redhat 7.3, took the crappy video card out that it came with........work on wine and halflife begins.....
