On motherboards with this 16meg cache problem (like mine), under DOS there are
third-party ROM cache programs to help get around this (or at least make
it a lot better).
Is it possible Linux could have it's own caching logic built into it for
kernels supporting >16meg? In other words, could we give Linux it's own
ability of dealing with this problem? I can't go out and buy a thrid-party
program to help linux.
