Bios Mods -The Best BIOS Update and Modification Source

Hello,

i try to update the microcode on this Bios:
ftp://download.hk.shuttle.com/Slim/XH61V...00.105.ZIP

With mmtool 5 i will see a lot of cpu microcodes but im not able tro modify. When i use the mmtool 4.5 i will see only two microcodes. if i do the changes and save the bios i will see with mmtool 5 that the half of al microcodes are gone.
What means the vol column since ver. 4.5? Maybe a compressed area?
I think with this tools ist not possible to do the changes?

Look in raw modules with GUID=(17088572-377F-44EF-8F4E-B09FFF46A070}
Note that one on them - in compressed section.
What's your purpose for microcode updating?

Nothing Special, just see if it possible and if i got it working.

So it is also not a Problem if it Fails, i can Programm the Flash outside, but i did not experimentet with bios patching already.

So but i got it working
With uefitool i extracted the body of your GUID then i replaced with a hexeditor the old microcode with the new one and replaced it back. After flashing i see in the Bios the new version

With mmtool 5 it also Looks good, but ony the second VOL-Section still have the old one. But ok no problem.
