UEFI BIOS Updater is a BIOS modding toolkit that allows you to perform an update for OROM / UEFI modules of an AMI UEFI BIOS without requiring advanced knowledge on modding techniques. Developed by a modding expert, UEFI BIOS Updater has scarce competition, being one of the few tools on the market that can perform BIOS modding with low chances of BIOS failures. The principle it relies upon is simple: provided with an AMI UEFI BIOS file, the program is able to detect the version of OROM / EFI modules in order to update them. The CPU microcode can also be brought up to date during the process.

The steps you need to cover in order to carry out the task successfully are the following: run it with administrative rights, provide the BIOS file you want to modify, choose the update to be applied and wait for the application to do its job.

The UBU tool has been designed and optimized for the modification of Desktop mainboard BIOSes. According the feedback we got until now the usage of the tool with Desktop mainboard UEFI BIOSes is very safe.
Nevertheless it is possible, but only recommended for advanced users, to update some modules of a Mobile system BIOS (except the VGA ROM!) by using the UBU tool.

This tool is very easy to use and able
to detect the versions of the OROM/EFI modules, which are inside an AMI UEFI BIOS file and
to update
a) the most important OROM/EFI modules (incl. various "Universal TRIM in RAID0 modified" ones) and
b) the CPU MicroCode
of any AMI Aptio IV UEFI BIOS.

Notes:
This tool cannot be used, if you want to
modify any other BIOS type (Award/Phoenix, non-UEFI AMI or Intel mainboard BIOSes) or
insert a BIOS module, which is not present within the original BIOS or
remove a BIOS module.
Problem with AMI Aptio V BIOSes:
The UBU tool uses the AMI Aptio MMTools v4.50.0.23 (for the older Aptio IV BIOSes) resp. v5.0.0.7 (for the newest Aptio V BIOSes) and supports all Intel and AMD platform BIOSes. Unfortunately the currently available AMI Aptio V MMTool v5.0.0.7 has problems with the update of certain BIOS modules of the latest Intel chipset mainboards (X99 and newer). That is why the UBO tool may not be able to update the BIOS modules of AMI Aptio V BIOSes (the tool will only show the version of the currently inserted BIOS modules).
Solution: It is possible to modify an AMI Aptio type V BIOS manually by using CodeRush's UEFITool, which is part of the UBU tool package. You can find a short guide within the start post of >this< thread (Chapter B).
Special problem with Intel's iGPU VGA ROM modules (=VBIOS):
Contrary to the other Option ROM modules there is no "universally" usable Intel VGA ROM module available for systems with an Intel CPU from Sandy/Ivy Bridge up. That is why the mainboard specific VBIOS settings have to be transfered by using a special tool named BMP to the desired Intel VGA ROM module version, before the UBU tool is able to update the VBIOS version (for details see below).
