Nice! It's getting even more juice to do this firmware upgrade to rev. 3.
I will try it with Rome too und report of the success.
just signed up to say that i have the same motherboard with AMD ROME CPU 7532.
i just flashed the 3.0 bios V34 and it worked without any issues
i was on lastest bios from 1.0 which is R28 and lasted bmc firmware which 12.61.21.
i flashed the RBU file using BMC webui and everything was smooth reboot to bios and it revereted back to default so i had to readjust the settings in the bios to my needs.
thanks to the others for testing it first
BTW my motherboard and cpu are from aliexpress
