S60V BIOS is here for the 760 Classified: http://www.megaupload.com/?d=3YYVXP2G

Download from there. Use winrar to extract the iso file.
CD/DVD Installation - Recommended installation method
Download the following .iso file: S60V.iso

Use a CD Burning software to burn the .iso image onto a blank CD (Nero, Alochol 120%, MagicISO etc.)

After it has burned, insert CD and restart the machine, go into the BIOS and load defaults, save and exit

Now set the CD Drive as the primary boot device, or press escape while the system is booting to select CD as the bootable device.

After flash remove the CD, and power off PC Completely.

Turn on the PC and load defaults in BIOS
