suryad Posted October 11, 2005 Share Posted October 11, 2005 May I ask why you are increasing the size of the DMA buffer? Are you hoping to gain overall I/O performance increases? Link to comment Share on other sites More sharing options...

eidenk Posted October 17, 2005 Share Posted October 17, 2005 there has got to be a program to find out the acutal dma buffer size. i'll be looking in to them later and post 1 on a new thread.Notepad will do.

grafx1 Posted October 18, 2005 Share Posted October 18, 2005 (edited) But i have Fresh UI software (tweaking program) and this option is dimmed there...do you know why? because it is 9x/ME tweak not for XP !! see this: http://imagebag.cfsmedia.co.uk/images/67731857.jpg Edited October 18, 2005 by grafx1 Link to comment Share on other sites More sharing options...
suryad Posted October 18, 2005 Share Posted October 18, 2005 I have reservations about using this tweak because I have not yet read a satisfactory explanation on the benefits of increasing this. DMA as I learned from my architecture class is a hack...an x86 legacy...for device drivers. No other hardware architecture uses this. Hnece my doubts.
