With quite a bit of consternation on AMD's Radeon RX 5600 XT release we figured it would be a good time to talk you through the process of flashing new firmware into a Radeon graphics card. We'll provide you the guidance and the tools to do so.

Read the guide here.

Does anyone tried to downgrade the bios of the Sapphire RX 5600XT with AMDVbFlash (dualbios) ?
I have find 2 (3?) .rom on techpowerup ; I guess they are the original one (december)

https://www.techpowerup.com/vgabios/?architecture=AMD&manufacturer=Sapphire&model=RX+5600+XT&interface=&memType=&memSize=&since=

I have 3 questions :
- does it work to downgrade simply by "Load image" ? Or does it need another step before ?
- do I have to : 1) loading the defaut mode, restart 2) loading the quiet mode, restart to downgrade both bios ?
- Do I have to uninstall the drivers first to avoid any problems after bios downgrade ?

If you want to know why I want to downgrade :
Linux isn't performing well at all on the new bios (drivers problem), but Linux was using the GPU perfectly with the previous one.
And I don't want to wait several months to have my dualboot working...

Answering that is going to kill all mystics. A Commodore 64 pun man ... the load and start program command. * Load the first application you can find from device 8 (disk) into 1 (RAM memory).

I KNEW I saw that before!!!

But I am so old, I couldnt remember where ... :-P
