5.2 CPU Installation and Upgrading

You can upgrade to a higher power Pentium® , AMD or Cyrix processor at any time. Simply remove the old CPU, install the new one, and set the jumpers for the new CPU type and speed.

5.2.1 System clock setting (JP11, JP8)

JP11 and JP8 are used to set the CPU and PCI bus speeds respectively, to optimize the system's performance. The system chipset will sense the JP8 setting to get the bus frequency, then adjust its internal timing. JP11 is used to set the CPU and PCI clock. Refer to the CPU speed reference table for instructions on adjusting the internal clocks according to the base CPU speed.
