Everyhing will work without drivers, they just won't have all their features active. The bios will 'drive' all the hardware in it's basic mode. I's like when you install a graphics card, you can't install nvidia/ati drivers before the card as without the card you get no display. So you install the cad boot into windows and then install the drivers, then once the drivers are installed it will allow you to use 3D graphics, standby mode etc...
So, just intall all the hardware, turn on, go into the bios (the pre-intalled will be fine unil you're up and running and ready to start tweaking) set in the bios the settings that you're planning on using (agp or pcie etc). Then stick your windows cd in and install windows.
After this you should then be able to install all the driver as necessary. The drivers are windows drivers and so can only be run from windows. The bios update can be done through DOS or windows, windows is easier and works well - bios 1.80 is the latest and is good.
Hope all goes ell - enjoy.
