There are two types of CPU burst modes according to manufacturer

Ø Interleave Burst (CPU: Intel P54C/P55C, AMD

K5/K6/K6-2, IDT WinChip C6)

Ø Linear Burst

(CPU: Cyrix 6x86/L/MX, Cyrix M

II

)

You do not need to adjust JP22 if you are using an Intel

®

P54C/P55C, an AMD ™ K5/K6/K6-2, or a IDT C6 ™ series

CPU. The default setting on JP22 is Interleave Burst Mode.

mode to Linear by shorting pin 1-2 on jumper JP22.
