On this model there is 100,105,114,120,124,128.5, 133.3, 138,143, 148,150,152,5, 155, and 160Mhz. Notice no support at all for speeds below 100Mhz
The Camino is designed to run at 133Mhz so rather than the convential 66/100 line (pin b21), you now get a 100/133 line. Thus to force your 100Mhz CPU to run on a 133Mhz bus, you can tape both pin b21 AND pin A14. You read it first at BXB
Note: Most boards will not require taping (this one doesn't!).
Check BXB voor meer info & pics.
