Drivers for what???
The computer's and/or motherboard's manufacturer's websites will have
drivers for your computer!
Vista has drivers as well.
It is better to get hardware drivers from the hardware manufacturer's
website, not windows update.
Drivers are either included in the operating system and will be available
during setup, or you will need to download them from the website of the
manufacturer of the device you are trying to use. If you require a driver
for setup, such as a raid or sata driver, you will need to obtain this from
the manufacturer and copy it to removable media (like floppy or thumb drive)
and load it at the disk detection phase of setup.
