Fernando or anyone who can please help me , i have tried to Mod the latest Bios 0404 for my new Asus P8Z77-V LK but i keep getting a message while trying to flash the moded Bios that says " "Security Verification" warning , i dont have a ROG board on this Z77 chipset so cannot do the ROG flashback
I ran into the same problem with my ASUS P8Z77-V mainboard.
At least I succeeded with the update of the Intel RAID ROM module this way:
  1. Take an USB flash drive, format it using the FAT32 file system and copy the modded BIOS onto it.
  2. Rename the BIOS file according to the PDF file, which you got with the latest ASUS BIOS.
  3. Shut down your computer, but don't switch off the power.
  4. Open your Computer case, look into your mainboard manual and search for the "USB BIOS Flashback Button".
  5. Put the USB stick with the modded BIOS file into the special BIOS Flashback USB port of the mainboard's Rear Panel and then hit the "USB BIOS Flashback" button for a few seconds until the BIOS flashback light starts to flash.
  6. Wait until the BIOS flash light signal has gone out.
  7. Start the computer, enter the BIOS and do your BIOS settings.
  8. Remove the USB flash drive.
If you should not have an "USB BIOS Flashback" button on your mainboard, you probably have to wait until ASUS releases a new BIOS version with an updated Intel RAID ROM module of the v11.5 series.
If you don't want to wait for a new official BIOS, you or someone else may try to fix the checksum of your modded BIOS according to >this< guide.
