<P>Nagyon ajánlott az MTRR helyes beállítása, mert minden esetben

sebességnövekedést eredményez. Először a báziscímet kell megkeresni.

<P>Helyes, ott látszik a Matrox G400-am 16Mb memóriája. Ezt a parancsot

<P>It is VERY recommended to set MTRR registers up properly, because they can

give a big performance boost. First you have to find the base address.

<P>It's right, shows my Matrox G400 with 16Mb memory. I did this from

XFree 4.x.x , which sets up MTRR registers automatically.</P>

If nothing worked, you have to do it manually. First, you have to find the base

address.
