Note: Cyrix 6x86 and AMD K5 CPU use P-rating for the
reference of CPU benchmark compared with INTEL P54C,
their internal core frequency is not exactly equal to P-rating
marked on the CPU. For example, Cyrix P166+ is 133MHz but
performance is almost equal to P54C 166MHz and AMD
PR133 is 100MHz but performance is almost equal to INTEL
P54C 133MHz.
Note: INTEL TX chipset does not support CPU with 50/55MHz
external bus clock, so that P54C 75MHz, Cyrix P120+,P133+
and AMD PR75 are not supported by this mainboard.
