lm_sensors and gkrellm should be on your CD's. Older Mandrake
releases might have lm_utils also. I've got (8.2b2+ cooker updates),
lm_sensors-2.6.2-4mdk and gkrellm-1.2.8-2mdk
If you're runnin 8.2, and get an error on boot somethin like
"Make sure that you have done "modprobe i2c-proc"
Error loading -4 ... /etc/sensor.conf"
I fixed it by puttin i2c-proc in /etc/modules .... altho
sensors worked fine inspite of the boot error.
The temp displayed in bios is for the most part useless. The
system hasn't heated up yet, and HLT's (halts) aren't being sent by
the kernel to the cpu. So while there's little load, there's no
idling either. Cpu core temp can rise and fall dramatically with load.
Shut down for some time, I'll see cpu temps from bios that are just
above room temp (~30C), but by the time I get to KDE they're in the
normal mid 40's.

Well, maybe you can get the info somewhere, but it should be on
their site. FWIW, my 1.4/266 Tbird is spec'd at 95C, but the 1.4 is
also the hottest cpu AMD makes. Your K6 should be lower, 80C, maybe
85C is probly a decent guess on the high end, but it could be in the
70's.

Without gettin too far into it, cpu's that are run too hot, too
long experience 'cpu creep'. There's actual migration and increased
resistance of the internal components. Once that's happened, there's
no going back. So it's good policy to monitor temp, and test
occaisionly with memtest86 and cpuburn. Another benefit of
monitoring cpu temp is you get early warning of runaway procceses,
even if the system seems fairly normal in use.
