[SOLVED] BIOS flash error on Asrock X570 Phantom Gaming ITX ?

[Trevor Johnson]

I am attempting to update my bios to allow support for my new ryzen 5800x. My motherboard is an Asrock x570 Phantom Gaming itx. I flashed the bios like normal to 2.60 and did not get a boot with the 5800x. The system still boots with my 2700 in the system however. From reading the bios update it states that using a matisse cpu requires you to do it a specific way to get it to work. Which led me to use the instructions from asrock here. When doing so I get an error of “ae- Error: BIOS doesn’t support OEMCMD function.” Would this error possibly be due to my bios already being on 2.60? Would it be a bad idea to downgrade to 2.30 and then flash it using those instructions?

Any suggestions would be greatly appreciated. I tried googling the error to no avail but that could be due to me not knowing much about bios stuff. Thanks for the help!

Update on this, it was as suspected. I had to revert to the 2.0 bios and then was able to follow that guide to accomplish what I needed.
