Chapter 2: Hardware information
2) CPU External Frequency Selection (SYSCLK DSW Switches 1–4)
This option tells the clock generator which frequency to send to the CPU,
DRAM, and the PCI bus. These switches permit selection of the CPU’s
External frequency (or BUS Clock). The BUS Clock multiplied by the
Frequency Multiple equals the CPU’s Internal frequency (the advertised
CPU speed).
