W15: Selects the desired multiplier to set the internal CPU clock speed (2, 3 or 4
times the external bus speed):
- Shorted: 2X (or 4X for AMD 5x86-133 only),
- Or open: 3X.
For DX microprocessors, external bus speed is set to the maximum CPU internal clock
speed or less.
For DX2 microprocessors, external bus speed is set to half the maximum CPU internal
clock speed or less.
For DX4 microprocessors, external bus speed is set to one third the maximum CPU
internal clock speed or less.
For 5x86 microprocessors, external bus speed is set to one fourth the maximum CPU
internal clock speed or less.
Jumper locations and settings appear in Section 3 of this manual.
