There are no Celerons with 128KB cache that run with a 100Mhz bus, AFAIK. > > "cpu MHz" the real current speed > > "bogomips" issome weird timing value I have no idea what it means exactly > It's a semi-arbitrary benchmarking value, usually twice the processor speed. > AFAIU. Depends on the chip. It is used to calculate the amount of time spent in a particular kernel delay loop. Some chips run this code faster or slower than others. It's not a benchmark as much as a calibration value. > This is what I guessed, I'm using the values specified in the manual for a > Coppermine FC-PGA 600, so: Oops.

It doesn't run exactly at 100MHz because it would be impossible to do so while maintaining synchronicity with a 33MHz PCI bus. 33MHz is actually 33.something, so you end up with 99.something when the FSB is running at 3x the PCI frequency. -- Ryan Underwood, <nemesis@xxxxxxxxxxxx> -------------- next part -------------- A non-text attachment was scrubbed...
