Before I say anything, I know its already been said, tho the solutions are really abstract. I recently got a pc with a KT266A chipset motherboard, and a Plextor 24x drive on secondary master on it, running under WinXP Home. The problem is that when I noticed that it was on DMA mode 2, not PIO and not UDMA33, which is where its suppose to be. I read on a previous thread about using a miniport driver and all that. Well first, it seems that when I checked out viaarena.com, it stated winxp does not need that driver, it needs a filter, and also that if I used the driver/filter some programs won’t work, like CloneCD, though its fixed with the newest update. On the plextor support page, it told me something bout uninstalling “the VIA drivers and re-installing the native Microsoft driver.” Does any of these methods work? And if so, how (plz be a lil detailed)? And if not, are there any other solutions?
