Ryzen - Return of the Jedi

[Formula350]

I've been playing with bioses from s.A era, have my own custom bioses, but haven't spent much time with newer tools.
I'm tempted to try a mod on my spare AB350 Fatal1ty. It appears all of the bioses of a given brand are almost the same, because they are still on the early productions stages and the different branches are not so different. Some things are hidden for specific boards, although it doesn't mean if you enable them they will do something.
I'm most interested in updating AGESA from one board to another. Can't get the latest mmtool though.

Yea, looking through my own MSI X370 Titanium, I was actually confused for a moment as I thought I maybe mis-labeled the ASUS B350 BIOS; however, my MSI's is way more polished in every regard. I'll admit that could be due to having opened the dump ROM instead of using the downloaded one. Either way, aside from board and vendor specific stuff, the meat of the BIOS is very similar. My Advanced DIMM area has full listings on what the timings are, compared to the ASUS which are all blank.

-_- I spent literally 2hrs trying to find a download link for that version of MMTool, but everywhere I looked, AMI had managed to get it pulled! Many thanks for that link


As for any CRC crap, I'm not quite able to find much. The best source of info I'm coming across is on the VoltGround forums and it says...

Critical: Please make sure your system is connected to the power source and you are not on battery only. Also, make sure your CPU and GPU is not overclocked/undervolted/overvolted while flashing. If they are please revert them back to default values before continuing any further. Failure to do so may prevent your system from booting properly if it has a random restart/shutdown or halt during the flashing process.

Step 5. Open AFUWIN again and this time click "Open" and select the modified BIOS you just saved in AMIBCP. Leave everything here defaulted. Just click "Flash" and allow it to finish completely.
Step 6. Once everything is green and is complete, you can close AFUWIN and restart your system and enter the BIOS to see your additional menus unlocked.

Still think I'm going to wait for Chew to be able to dump one, simply based on this tidbit:

As for the signed CAP. Simple workaround is dump your current BIOS (AFUWIN64) and open it up in UEFITool and you should notice the CAP is removed.

If you download any version of BIOS on ASUS support page and not make a current dump of your own, and apply hex edit changes without removing the CAP on the downloaded BIOS, then yes, you could potentially brick.
