The UEFI BIOS should now be fully re-flashed and updated! Reboot and give it a try!.Flash the modded BIOS by running the following Command Prompt as Admin:.Replace the original *.CAP BIOS file within the AFUWIN64 folder by the modded *.ROM BIOS file.This is normal and nothing to worry about. Note: Due to the removed capsule header the *.ROM file is a little bit smaller sized than the original *.CAP file. Removal of the BIOS Capsule Header.png 802×280 9.48 KB Open the *.CAP file, do a right-click onto the listed 'AMI Aptio capsule', choose the option 'Extract body…' and save it as *.ROM file.Here is the way how to do it by using the latest UEFITool version (you can get it >here<): The removal of the capsule header can be done by several BIOS tools. Remove the capsule header from the modded *.CAP BIOS file and save the modded BIOS as *.ROM file.

For details please look into your mainboard manual or at >thisherehereAMI AFUWin64 v3.05.04. These boards have a special 'Flashback USB port' and a special 'USB Flashback button'. Many ASUS mainboards with an Intel 7- 8- or 9-Series chipset do support this very easy to use feature to get a modded BIOS flashed. Usage of the ASUS “USB Flashback” feature (easiest option): There are at least 4 options how to solve this problem:ġ. These types of ASUS BIOS files are capsuled and write protected, which makes it impossible to flash a modded.

That is why it should be no problem to get an accurately modded BIOS flashed into the BIOS chip by using the ASUS standard tool named “EZ Flash”.įlashing an ASUS BIOS file with the extension “.CAP”: It is most common for ASUS P67 and Z68 mainboards. This BIOS file type is not capsuled and usually not write protected. The Company AMI itself offers >hereherethisherehere< (Lost_N_BIOS’s Guide).įlashing an ASUS BIOS file with the extension “.ROM”: The problem is, that the tool may detect the alteration of the BIOS and refuses to flash it. That is why I recommend to use either a BIOS flash tool from within the UEFI BIOS or a flash tool, which has been put onto a bootable USB Flash Drive with a DOS environment.Ī very safe method to get a modded BIOS properly flashed is to use the 'normal' BIOS flashing tool the mainboard manufacturer is offering within the BIOS.

The most risky flashing procedure is the one from within a running OS. Since SoniX has presented his wonderful UBU tool (look >here “Show advanced options” > “Rename”).
