Bios is compiled by Asrock but they can not offer it officialy with renoir support - amd will be angry, so they released it via their eu distributor. That's how business in todays world works, buy more and more new sh*t every year and as manufacturer pay extra duty

Hi Serj47,

I had issues with the BIOS v3.6 that came from the factory.

I upgrade it with the BIOS v3.6K that is in BETA on [URL=https://www.asrock.com/nettop/amd/deskmini%20a300%20series/index.asp#BIOS]Asrock A300 Bios web page[/URL].

I saw that JZ offers newest beta BIOS, but as how he can have/compile newer BIOS than Asrock, I stayed on the safe side.

Best regards,
djax

I have BIOS 3.60K and linux mint installed, and I have never experienced any problems with loading. Which BIOS version does the system fail to boot with?

The only problem that bothers me is errors when loading the kernel, "AMD-Vi: Unable to read / write to IOMMU perf counter"
I enabled iommu = on and amd_iommu = on in the kernel boot parameters, and virtualization in the BIOS, but that didn't help ..
1.Advanced - AMD CBS - nbio common options - nb configuration - IOMMU Enable
2.Advanced - North bridge configuration - SR IOV Enable
3.Advanced - CPU config - SRVmode Enable

cpu = Athlon 200GE

Thank you.
I unplugged the cables,
cleared the CMOS,
removed the nvme drive,
put keyboard and power
updated the BIOS to the 3.60K,
unplugged the power,
put back the nvme drive,
plugged back the cables,
start, restart
and it WORKS!!!


Have a nice day

After certain Grub updates on Linux Mint 19 I also experienced the black screen you are describing. Rolling back this Grub update fixed the issue but of course this cannot be your solution. Since I have flashed Beta BIOS 3.60K the problem is gone for months, it has never occurred again. Also the Grub Update was possible without any issues.
I recommend to use the latest Asrock Beta BIOS 3.60K as it fixes several issues including yours.

Hello,

I have the same problem. I have installed the last Ubuntu 20.10, but after the restart, the screen stays black. I clear the CMOS and a normal boot occurs, but the screen stays black again after the reboot.
My config:
MB: AS300W with the 3.6 BIOS
APU: AMD Ryzen 5 3400G
RAM: 2x16 GB Corsair Vengeance
Storage: 1x Crucial P1 (CT1000P1SSD8)

Does a beta version of the BIOS fix the issue?

Best regards,
djax

No JZ recommendation for the 3.60L, too many BUGs I noticed.

A new BIOS with AGESA V2 1002 will come.

Hello J Z,
Have recognised that you have created a new BETA BIOS P3.60L thanks for that.
But I must say that I am not brave enough to flash it, I would prefer official downloads from Asrock. Do not want to brick my A300.
Has anyone else tested it?
Does this support 4700g already?
Thanks
