The bogomips rating for the K6-2 is about right - the K6 family usually
achieves 2x the clock speed (in MHz) for the bogomips rating. There's
something very wrong with the configuration for the PIII, however - the
PII/PIII score around 1x the clock speed (in MHz) so your machine should get
around 450 bogomips. My PII-240, for instance, gets 239.8 bogomips.
Number one cause of a suspect bogomips rating is the processor cache. Go
into your BIOS setup, and make sure that both the L1 and L2 caches are
enabled - in most Award BIOSes, cache options are found in the 'Chipset
Features' section. Whilst you're there, make sure the main memory settings
are sensible. If you're not familiar with fiddling with the BIOS, it may be
worth your while to use default settings - most Award BIOSes (I have no
recent experience of an AMI or Phoenix BIOS) have both a standard default
and a turbo default - go for the turbo default settings. You won't get
absolutely optimal performance from these settings, but it'll be reasonable.
Number two cause of a suspect bogomips rating is that the processor is
clocked at the wrong speed. What speed does the BIOS report when the
computer is first turned on? It could be that the processor is set to a low
speed, or too high a speed. Most PII/PIII/Celeron chips now are multiplier
locked, so the frequency multiplier must be right - if it isn't, the
motherboard will default back to a _VERY_ low speed - on my motherboard, it
defaults back to 133MHz if the multiplier is wrong. The multiplier should
be 4.5x for a 450MHz PIII. If your motherboard is jumperless, you should be
able to set this in the BIOS too - in fact, there should be a default setup
for a 450MHz PII/PIII, if the motherboard is fairly recent. Otherwise,
you'll have to get out your motherboard manual and fiddle with the jumpers
on the motherboard. :-(
We'll get to the bottom of this, don't you worry... :-)
