New Motherboard, faster processor and an airplane in my living room...
So, now I finally got on eBay and found a pulled mATX motherboard with an Pentium 4 Mobile processor and some memory on it already. Perfect! Just have to load a module and - voila! - I can set the CPU frequency governor to "ondemand" and get a 350 MHz processor when "just using" the system. Excellent! Now I just have to figure out how to set this governor at boot time... and change the CPU fan. The fan which came with the board is a really stupid one, going at full speed and sounding like a small airoplane even when the CPU is at 350 MHz and should not be in such a big need of huge amounts of cooling. I wonder why this fan was ever used... well, I will get a new fan anyway - that's for sure! :-)
