Re: DMA Problem
This shouldn't be a problem because my laptop is an IBM A31p which means
P4-M 2.0GHz and an Intel i845 chipset.
And I know this configuration works because to of my friends have the
same notebook and it works just fine there. But we were not able to
figure out what's the difference between their machines and mine.
