Note: Cyrix 6x86, M2 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 INTEL P54C 75MHz, Cyrix
P120+,P133+ and AMD PR75 are not supported by this
mainboard.
