cpu: k63-450, k62+550
videocard tested: geforce256 and rage128pro
ali agp and ide driver installed
lots of agp trouble
for geforce256, old drivers(23.11 and older) refuses to enable agp mode and runs in pci mode only, with no known method to turn it on.
using drivers newer than 23.11(i tried 28.32 and 30.82), i can use the "enablealiagp" registry command to turn agp mode on, but then i must disable onboard cache to boot windows(which appears to have only 2-3% impact on performance anyways), or it gives a bsod during loading. even with onboard cache disabled, d3d games/benchmarks still crashes easily, and opengl icd always stop responding whenever accessing it, including just checking icd info in everest.
then i turned to ati cards(which is hateful cause i am loyal fan of nvidia) which gave just slightly less trouble. agp mode is on, but still crashes easily in 3d games and watching video with onboard cache on. again the only workaround is to disable onboard cache, and it managed to pass a few tests without being seen crashing yet.
the only good thing is that at least it solved the previous problem of incorrectly detecting cpu frequency.
