@tistou77:
Yes, you can insert any additional module by using the UEFITool or the AMI Aptio MMTool.
If you want to insert an EFI module, you can just follow the related part of >this< thread, which I have written for the insertion of the NVMe EFI module.

But nobody replied to my posts.

@kyriacos:
As far as I remember, you had problems to get an UBU modded BIOS properly flashed.
Since the flashing procedure has nothing to do with the sort of BIOS modding, I had moved your post into >this< thread.
Note: A BIOS with a wrongly updated BIOS module can be successfully flashed without any problem (but the related function or the complete system may not work thereafter).
Within this Forum nobody moves posts from one thread to another without any reason or thinking.

After flashing I found that in the bios setup the old microcodes were still showing and used.

@kyriacos:
... and then you have realized, that your CPU was still using the old and not the new Microcode?
Please copy the text of your moved post and reinsert it into this thread, but don't forget to directly address it to SoniX by entering an @ in front of his nickname.
If I would simply move the post and add the directly addressing, SoniX would not get a notification.

@kyriacos:
Ok, you surely know, that the UBU v1.71 has not yet been finally developed and was offered just for testing purposes.
Nevertheless SoniX would be interested in the following details:
1. After having done the task "CPU Microcode Update" by using the UBU test version, did the UBU tool show the updated CPU Microcode correctly? Have you checked it by opening the modded BIOS with the latest official UBU version?
2. Are you sure, that the BIOS, which had been updated by the UBU test version, was properly flashed?

@kyriacos:
Thanks for having answered my questions.
For me it is hard to believe, that a BIOS with demonstrably updated CPU Microcodes has been properly flashed into the BIOS chip of the mainboard, but the in-use CPU Microcode is still the same as before the flashing procedure.
