That particular box of mine contains an ISA VGA graphics card with 256 Kbyte video memory. It's a server, not a desktop machine (in fact it wouldn't need a gfx card at all, but it's more convenient than a serial console). > The MTTR stuff is an old hack which some motherboards enabled it > automatically for you. > > So to answer your question , the MTTR stuff is supposed to disabled caching > to your VGA card. OK, so it has nothing to do with disabling caching for my main memory, which was my concern. :-) Thanks for making that clear. BTW, is there a way to disable that MTRR stuff? Just to be sure... And I really don't need it.
