I have a Beelink SER5 MAX (Ryzen 7 5800H) with BIOS Version/Date: American Megatrends International, LLC. 5800H602, 6/15/2023.

My problem is that I can’t see the BIOS screens on a Hisense HDMI TV used as a monitor. Once Windows moves into the graphical screen it works, but it doesn’t seem that the MiniPC is providing an acceptable HDMI signal during the BIOS and early boot screens. If I move to an old Dell monitor it works correctly.
Where can I download the updated BIOS? Links to dr.bee-link.cn don’t seem to be accessible. Are you able to send me a direct link to the updated BIOS?
Are there newer drivers available for this Mini-PC as well? Can you provide a download link to any other new drivers for this hardware?
