bios tweaking for performance

more and more is being published on this arcane artform. lol.
but seriously, some good memory bandwidth and information transfer gains are to be had by tweaking your bios.
the only trouble is getting in there first.... with most ibm clones its as simple as pushing the delete button just after you start up your pc. (when it says "press delete to enter setup")
unfortunately this does not work on compaq and ibm machines (just to be difficult i think). i recently discovered this when trying to tweak some friends pc's.
but i found the solutions after a bit of digging on the net and i thought i would share:
ibm: press F10 when the ibm splash screen first shows at bootup
compaq: press F1 when the compaq splash screen first shows at bootup
here is one of many guides on how to tweak your bios for optimum pc performance:

and heres another:

and here's a program that does it for you if you have one of the supported motherboards (there is a list of these on the page). i've never used something like this cos i like to tinker with settings myself, so dont blame me if it goes wrong!
