Here are the steps to take in order to get a working driver disk you can use
when booting the Windows XP for AMD 64-bit installation CD and hitting F6 to
specify additional drivers:
1. Download the VIA Hyperion Pro driver archive from VIA's site:
http://downloads.viaarena.com/drivers/Hype..._HyperionPro64_ v096P2.zip
2. Extract the contents of the archive downloaded in step one using winzip.
3. Extract the contents of "VIAHyperionpro64-096P2.exe" (the only file in
the archive you downloaded in step 1) using winzip.
4. Open the "SATA" directory.
5. Open the "driver" directory.
6. Copy the "X64" directory and its contents to a blank floppy.
7. Save the text below between ;;start and ;;end to a file named
TXTSETUP.OEM in the root of the floppy.
;;start
