Installing Drivers and Software It is important to remember that before installing the driver CD that is shipped in the kit, you need to load your operating system. The motherboard supports Windows XP 32bit and 64bit and is Vista-capable.
Windows XP Drivers Install When installing the graphics drivers, the resolution defaults to the lowest setting (typically 800 x 600), making your display very large. Adjust accordingly. If you have multiple graphics cards installed, you will be asked multiple times for all events once the drivers are installed.
NVIDIA Performance Group of NVIDIA Control Panel Note All changes made within NVIDIA Performance Group are dynamically applied, and will only remain active for the current Windows session. You can save these settings as a profile by using the Profile menu item.

Motherboard All changes on Adjust Motherboard Settings are dynamically made when you apply them, and only remain active for the current Windows session. You can save these settings as a profile for use later by using the Profile menu item. If a setting does not allow a change, it probably requires a reboot and should be changed in the BIOS or from the Dynamic BIOS Access...
