Linux reports incorrect CPU speed



Hello all,

Have had lots of probs with this laptop and decided just to reformat the hard drive and reinstall Debian (for the first time ever - oh the shame) even tho all probs would be fixable - but I needed a working laptop. Anyway it's all working but KDE feels very slow, and looked up the CPU speed and Linux reports it to be 259MHz while it should be 750MHz as the BIOS reports.

When using the 2.4.26 kernel with custom .config file. Taking the info from dmesg:

Initializing CPU#0
Detected 258.884 MHz processor.
Calibrating delay loop... 534.11 BogoMIPS
CPU: L1 I cache: 16K, L1 D cache: 16K
CPU: L2 cache: 256K
Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#0.
CPU:     After generic, caps: 0383f9ff 00000000 00000000 00000000
CPU:             Common caps: 0383f9ff 00000000 00000000 00000000
CPU: Intel Pentium III (Coppermine) stepping 0a
Enabling fast FPU save and restore... done.

From cat /proc/cpuinfo:

piers@delirium:~$ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 8
model name      : Pentium III (Coppermine)
stepping        : 10
cpu MHz         : 258.884
cache size      : 256 KB

While using the stock bf24 kernel - dmesg reports:

Initializing CPU#0
Detected 746.766 MHz processor.
Calibrating delay loop... 1490.94 BogoMIPS
Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#0.
CPU:     After generic, caps: 0383f9ff 00000000 00000000 00000000
CPU:             Common caps: 0383f9ff 00000000 00000000 00000000
CPU: Intel Pentium III (Coppermine) stepping 0a
Enabling fast FPU save and restore... done.

and doing cat /proc/cpuinfo gets:
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 8
model name      : Pentium III (Coppermine)
stepping        : 10
cpu MHz         : 746.766
cache size      : 256 KB

Any ideas how I can fix this?

Thanks very much for your help in advance!

Cheers - Piers
