I have a abit KT7A board (via kt133a chipset). This board has an "Enhance Chip Performence" option in BIOS, previously I have been able to boot athlon optimized kernels with that option off, and anything but athlon optimized kernels with it on. Now with 2.4.14 I can boot an Athlon optimized kernel with it on. (I wonder what that option _really_ does -guess I'll have to find some benchmark to run now...)
