I've just built a second computer using the MSI MEG Z790 ACE with a 14700k, so flashing the BIOS isn't terribly new stuff to me. My current one is using BIOS 7D86v19, so I was planning on updating mine after this new PC to update the CPU microcode.
But. I go to flash the new motherboard with 7D86v1D using the flash button and it just will not take. The light blinks 6 times, then goes solid. Thought I bricked the thing, but luckily not. I loaded up 7D86v19 to the drive and flashed it, and all seems to work fine. My question is now what do I do?
I know it has dual BIOS, so should I flip the switch, flash BIOS B to 7D86v19, then try and flash using M-FLASH in the BIOS to 7D86v1D or try 7D86v1C? Just wondering what the best way to try and get this new BIOS with updated microcode, without bricking my systems now, seeing as how it seems to have issues taking the newest version.

Best way to use MFlash, if you can get to the settings with the first one use that to do the flash. If you can't, flip the switch to get into the BIOS. You can flip the switch back and then update it to keep your secondary BIOS safe.

realistically speaking bios dont matter nearly as much if your hardware is supported unless its for the issue with the cpu's getting messed up via the microcode crap that happened to intel.

But that's exactly what we are dealing with here. Literally, as far as the importance of BIOS updates goes, there is nothing more important than to update the BIOS right away, if you're using an affected 13th/14th gen CPU.

About the BIOS of any modern board being "banaware", and you're usually much better off updating it first thing when you get a new board, i wrote about here before for example. On Intel or AM5 800-series boards you can see that even this is not enough; the BIOS is (in parts) so immature that the users are impatiently waiting for new beta BIOS updates to fix some annoying bugs or shortcomings.

If you buy a board relatively late in the product cycle (let's say more than a year after it came out), you can usually get away with updating the BIOS to the latest version after putting the system together, and then you might not have to do it ever again. But running it on an old factory version forever, there can be bugs that are long fixed in newer versions that just annoy you and cannot get rid of other than by a newer BIOS.
