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.
Caution: Following table are possible settings of current
CPU available on the market. The correct setting may
vary because of new CPU product, refer to your CPU
specification for more details.
Warning: Cyrix 6x86 P200+ uses 75MHz external clock,
the jumper setting shown on the table below is for user's
convenient. It may cause serious system damage to use
75MHz clock.
