people knowing chipset options are not necessarily programmers. a menu
like the current bios implementations offer would be nice to have.

because there are chipset options that shouldn't be set according to the
manufacturer but they do have in fact an impact on performance.
the best example are ALi chipsets: if you leave everything unconfigured
the chipset will be dead slow. if you set everything to optimal
performance some (pci) devices could run into problems. the user should
have at least the options to flip some bits if something isn't working
correctly.

agree! i wish the chipset manufacturers would have written those
information in their chipset documentation. that would make things so
much easier. i guess the main reason why they made those options
adjustable is the fact that there is so much different hardware out
there that cling to different (more or less officical) specifications.
that makes it almost impossible to find the optimal setting for every
possible combination.

and there are so many more..i didn't find anything on PCI performance
benchmarks but some tweaks modify pci performance registers, too.
i should definately do some tests on a pcchips board regarding pci
performance..
