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.
