To get full support from the new OROM it's a good idea to redo the array and re-install Windows after you have flashed the updated BIOS.
ASUS Z77 / Z87 / Z97 users will need to use the USB BIOS Flashback feature to flash a mod BIOS, EZ-Flash 2 wont work it will show an error while attempting to flash "Security Verification Failed".
Targeted OROM and Driver per chipset:
Ok, just a quick question, i downloaded the 2303 for my p8p67 v3 on asus support page and upgraded the bios with my usb stick.. But when i push ctr+l on start up, i still see version 10.5.0.1034. is this correct? i was expecting to see version number 18.104.22.1683
Edit, i figured it out.. These are modified. i now have 22.214.171.1243.. thanks
