Hey everyone. I have a couple of BIOS setting questions I am hoping
someone
could help clear up for me here. I am running WinXP SP2 on a P4 1.5 Ghz
system with an ASUS P4B mobo and AwardBIOS.

I just bought an 128mb ATI Radeon 9600XT after Christmas to replace my
64mb
PCI GeForce4 MX for better gaming. So far, so good; but I wasn't impressed
with the quality of watching video files (mpeg, avi, etc.,) full-screen
with
this new card compared to my old GeForce, so I decided to see if I had to
change some BIOS settings to accomodate the new AGP card. I had totally
uninstalled the old GeForce card before installing the new ATI one
(drivers
and software), but wasn't sure if I had to change some BIOS settings to
accomodate new AGP card.

The first two settings I changed was under Chip Configuration where I
changed the Optimization Mode to Turbo 1 from Normal (options were Normal,
Turbo 1, Turbo 2). I know my MOBO book said Turbo mode enhances system
performance, but how and is it good to have on.

Next, I changed Graphics Aperture Size from 64mb to 128mb. Is this okay?
My
book said this feature allows you to select the size of mapped memory for
AGP graphic data. With the card being 128mb, does this mean you set this
setting to 128mb or am I totally misunderstanding what this setting means?
Lastly, I changed Primary VGA Bcard under PCI Configuration to AGP VGA
card
from PCI VGA card. What is this setting for and should I have left it on
PCI
VGA card for some reason?

Sorry for the length of this and thanks for any help in advance. Also, if
there are any BIOS settings I was supposed to tweak or change, feel free
to
let me know what I may have missed.

Thanks again,
Mike
Bios settings may alter the performance slightly but not the image quality.
Radeons have slightly better image quality than Nvidia - when I went from a
Geforce to a Radeon I noticed slightly sharper DVD with more natural and
less saturated colours.
I would uninstall and reinstall your Media Player and codecs and see if that
helps.

btw only put Bios settings from Normal to Turbo if you have good low latency
RAM otherwise you risk making your PC unstable.
