SubjectBogus BogoMIPS on ThinkPad? [Entertainment for Linus]
When my ThinkPad 600E boots Linux says that it has a 75 MHz CPU,
but my BIOS tells me it has a 300 MHz CPU -- whats the deal?

Linux version 2.4.9-13 (
(gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)) #1
Tue Oct 30 20:11:04 EST 2001
Initializing CPU#0
Detected 75.431 MHz processor.
Console: colour VGA+ 80x25
Calibrating delay loop... 169.98 BogoMIPS

My guess is that the TP is doing me a favour by running the
CPU at a reduced speed to save my battery. I'm running
with my charge plugged in so I'd like to have my BogoMIPS back.

The BogoMIPS HOWTO says:

The reasons (there are two) it is printed during boot-up is that
a) it is slightly useful for debugging and for checking that the
computers caches and turbo button work, and
b) Linus loves to chuckle when he sees confused people on the news.
