Correct CPU/bus frequency on a wallstreet.

Hello all, maybe be a bit OT but I hope to get an answer here. Since a few months I'm really happy! I got an increase of the CPU and the bus clock for free. I own a Wallstreet I from summer 98 with G3 250MHz CPU and 83 MHz bus clock. As said, the Apple profiler and the OF tells me since a few months I have a 300MHz CPU and a 100MHz bus clock, great, but I can't believe! I can't remember when it changed. The different Cache utilities and the Metronome app all tell me the expected CPU and bus clock. Yesterday I wanted to see what's going on with my L2 cache on the linux side. So I saw that I have there 300MHz too, a look into the code showed me that these values are taken from the OF, right? But the so called Bogo value 'seems' to be correct, twice the cpu clock. Also, who sets the L2 cache? Is it BootX and or G3/G4 Cache porfiler? On the Mac side I run a value of 0xB5080000, on the linux side it is: L2CR overriden (0xb5000000), backside cache is enabled So what I'm wondering about how and who changed my cpu/bus values in OF? I didn't play wit OF, and I'm quite sure that I reset the whole machine quite a lot during the past months. And how becomes that e.g. a Powerlogix Cache profiler can tell me the expected values. And even the temp of the cpu (I read that there are some attempts regarding temp in bk_2_5, right?) Is it the right way to rely on OF for these values? This topic is not life critical, sure. Any insight??? Thanks for response Cheers Andreas ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
