Kernel Configuration

OK. You're about to configure and build a new kernel. Check your disk support - If you've got ATA support built in, take it out! You don't need it (unless you have a CF adaptor plugged in?). You certainly don't want it, unless you like watching paint dry. Check the benchmarks for the cdparanoia test... This, folks, is why we like to build our own systems, rather than rely on prebuilt distro's. Note: You probably do not want to build the kernel drivers as modules, as you won't be able to access the disk drive in order to boot!

USB Pendrives

I suppose this entry actually belongs elsewhere. However, this page is more complete, and it seems to fit better here! I have an issue with one of my two USB pendrives being recognised. It works in every other system, and on this one with a different OS. Therefore I guess I have a kernel module missing. I didn't realise there were multiple drivers for different USB drives. I shall update this page when I work out what I have done wrong.

Performance Tweaking & Monitoring

I am unaware of any utilities to really tweak the performance of either the disk, or the CD drive. Although the drive is SMART capable, I have not been able to enable this feature under Linux yet. Nor can I change the accoustic setting or R/W multiple sector transfer. Within the functionality listing, there is also detailed a 'SET MAX security extension' ability. I am unaware of what this is, what it provides, or how to activate it... Currently my settings are as follows:

> hdparm -a -S24 -W /dev/sda > hddtemp -D /dev/sda - Drive not currently recognised by default. Add this to your hddtemp.db.
