This is not a secret any more. Loser technology and constant illegal copying will lead to inferior CPUs with bugs.

Under W95: open a DOS prompt, start debug, and at the '-' prompt, type:

a<Enter>
db f0,0f,c7,c8<Enter>
<Enter>
g<Enter>

Under Linux, compile and run the following C program (with optimization,
"gcc -O"):

void main() {
__asm__(".long 0xc8c70ff0");
}

Both OSs should report an illegal instruction if your CPU is up to spec, and lock hard if it has the bug. But my K6-233 is fine...
