[. . . ] Tip: Normally, for single voltage CPU, Vcpuio (CPU I/O Voltage) is equal to Vcore, but for CPU that needs dual voltage such as PP/MT (P55C) or Cyrix 6x86L, Vcpuio is different from Vcore and must be set to Vio (PBSRAM and Chipset Voltage). The single or dual voltage CPU is automatically detected by hardware circuit.

Warning: INTEL TX chipset supports only 60/66MHz external CPU bus clock, the 75/83. 3MHz settings are for internal test only, set to 75/83. 3MHz exceeds the specification of TX chipset, which may cause serious system damage. Warning: Cyrix 6x86 P200+ uses 75MHz external clock, the jumper setting shown on the table below is for user's convenient. [. . . ] Warning: Although you may set 75MHz x 2 for Cyrix MX-PR200 and 83. 3MHz x 2 for Cyrix MX-PR233, note that 75/83. 3MHz settings may probably cause serious system damage.
