Good afternoon,

I was hoping one of you could asisst me or at least point me in the right direction on how to tackle a problem I am facing. I am currently in the possesion of an HP EliteDesk 705 G3 which currently houses an A10-9700 CPU which I would like to upgarde to a Ryzen 3 pro 1200 I have lying around. I examined the most recent bios from HP (P06_0237.bin) with MC extractor and found out the latest bios only supports the Excavator Carizzo APUs. The bios file from HP however, also included the bios for the tower model of the HP EliteDesk 705 G3(P09_0237.bin) which does contain the microcode for first generation Ryzen processors. I wonder whether it would be possible to add the microcode for these processors to the P06_0237.bin bios file. I have extracted the required CPU microcode files with MCExtractor and uplaod them to mega together with the bios files(please pm me for the link as I cannot post it yet due to having insufficient posts).

I have already tried the mmtool and CBROM tool buit I was not able to read to bios file using any of these. I wonder whether one of the members on the forum here has any experience or insights to share into adding the extracted CPU microcodes to the P06_0237.bin bios file.

Kind regards,

Dave
