I remember this now, I was one of those that got bit by this problem. What
I recall is that MTRR support made a dramatic speed improvement, but alas
was _extremely_ unstable. That was when I had an ATI Expert@Work card.
Since then I've gotten a 3dfx Voodoo3, perhaps this card might be more
stable? So Brian, how do I switch this back on ?
On the other topic - write allocation - should I be seeing an indication
of its status in the boot up messages ? Hmm, I guess I could just UTSL on
this one :) ...
Andrew.
