Has anyone had experience with the Biostar IDEQ 200P 64 bit system?

I have one. I have almost given up running Linux on it since there is some odd interaction between Suse 9.0 64 bit and the cool and quiet features of the CPU. If you load the CPU then the machine slows down over a few minutes to about 10% of its normal speed. I have tried disabling acpi in the BIOS (so far the nearest thing to working), starting the the kernel with acpi=off, told cpufreqd to run the processor at full speed, and all of these things change the problem. I havent yet found a solution however. I have to assume there is a BIOS/Suse incompatability here. It runs windows great though. Biostar give you a program that manipulates the fan and processor speed according to CPU temperature, and it keeps the fan noise down and the performance up.
Hi Robert, I think you should disable "cpufreqd" which tries doing similar things under Linux. However, this can cause a slowdown, in my case (Shuttle SN85G4) this was down to 800 MHz. Otherwise, you can do echo 2000000 >/proc/sys/cpu/0/speed for a 3200+, or simply cat /proc/sys/cpu/0/speed-max >/proc/sys/cpu/0/speed in general. I is weird, that while the value for "speed" is reported in MHz, "speed-max" and "speed-min" are given in kHz, and kHz should be used for changing the speed of the processor.

Hi Robert,

rccpufreqd high does this also.

cat /proc/sys/cpu/0/speed-max >/proc/sys/cpu/0/speed
in general. I is weird, that while the value for "speed" is reported in MHz, "speed-max" and "speed-min" are given in kHz, and kHz should be used for changing the speed of the processor.
cpufreqd gives you a fast CPU when needed - and otherwise slows it down to save power and noise, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

You can disable the k8 powernow driver by doing rccpufreqd stop rmmod powernow-k8 chkconfig cpufreqd off (the chkconfig will prevent loading it after the next reboot) -Andi
