I am using ECS K7VZA (KT133a chipset) and Athlon. I
complied my 2.4.17 kernel with Local APIC support. How
do I know is it working or not? I have to use the
performance counter and local timer interrupt feature.
Many Thanks

All K7s except the very first model (K7 model 1) work, unless
your BIOS is broken. Since you have a VIA chipset, you may see
spurious IRQ7/ERR interrupts. We don't quite know why, but it's
not fatal. Disabling LPT support in the BIOS _may_ help.

This is not ENTIRELY true. Certain hangs and crashes can be caused with
X, APM, and APIC enabled. I haven't entirely tracked it down yet, but I
have seen it on a Thuderbird 800 (FIC SD11), an Soyo Dragon Plus (1800+
XP), and a few others. It goes away if you turn Local APIC's off. This
may be related to some video card issues, but I don't yet know.
