My laptop has a 700/550 pIII cpu in it running Slackware 9.1 but it only
seems to be running at 550mhz. Since the battery is screwed and it is
only run off the mains is there any setting in Linux to get it to
run at 700mhz??

Thanks

Hugh

What does "cat /proc/cpuinfo" return?
Especially the "cpu MHz" line. If that value is wrong, you should go
into your bios (which is different for each machine/laptop) and try
to find out where it reports ITS speed for the cpu, Linux is getting
it from there (and only the bios will know how to change it).

Just change it in the computers bios.

I'd upgrade to kernel 2.6.0. Or patch 2.4.23 for cpufreq support.

Either of those options will give you cpufreq support in the kernel,
which will allow you to dynamically set the speed of the processor via
a nice /proc or /sys interface, with user-land utilities available to
set it based on CPU load. It's good stuff.

Note if it is a Dell laptop, you may be unable to use any but the acpi
drivers to change the CPU speed. I'm not sure exactly why and those who
do know exactly why seem to be bound by Dell and/or Intel NDAs.
