Disabling BUS MASTERING?

[DJATWORK]

I´d like to know how to disable the AGP Bus Mastering.
I own an ATI Radeon VE (dual head), but in the Pulsar2 manual only appear the way to do this with any Matrox card.
Anyone has the information for universal AGP Bus Mastering disable?

Thanks!!

This is part of the Matrox settings. You more than likely don't have an option like this on an ATI card.
