2-3 CPU BURST MODE JUMPER (JP22)

There are two types of CPU burst modes according to manufacturer design:

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.

If you are using a Cyrix ™ 6x86/L/MX/M II series CPU, set the burst mode to Linear by shorting pin 1-2 on jumper JP22.
