I am currently using bios version 1.06 on my Reatan Alloy 9, downloaded from the Reatan drivers section back in June 2026. I looked today, and the Reatan drivers section has changed. now they list drivers for "A9" , and neither Alloy 9 or A9 show up on the Reatan shop anymore. I was directed to the "Hub-union" website, apparently the parent company for Reatan. They offer drivers for "A9" as well, but their shop lists an identical model to the Alloy 9, as "R9".
Anyways, I get that A9 can mean Alloy 9, and R9 can mean Alloy 9, and all of these are describing the same mini pc.
My question is, when i downloaded the "new" drivers from the Reatan site for the A9, it has a version 1.09 (CTO) bios updated in August 2025. I have in the past, just for fun and education, looked at the minisforum um790pro bios revision history, which is 1.09. Since both the Alloy 9 and the Um790 pro both use the same Um790pro motherboard, just a different case, it seems logical they would use the same bios, but i never tried to do that. Now the Reatan driver download has a 1.09 (cto) bios and the revision history follows the minisforum bios revision history, not the Reatan bios revision history in the 1.06. However, the Reatan 1.09 (CTO) revision history does list as the last revision that:
"BIOS Description:
1.Modify DMI MANUFACTURER to Shanghai Hongnian Industrial Co.,Ltd.
2.Modify DMI SKU to ALLOY9-7940HS-1
3.Add REATAN logo"
So does this mean that I can safely install this 1.09 (CTO) bios on my Reatan Alloy 9? If I install this bios, and turns out to be incorrect, is there a way to install the older 1.06 Reatan bios, that i do have the zip file backed up? Should I worry about the users that got a black screen after updating to 1.09 3 years ago? Is there even anything to be gained from "updating" my bios?
Here is a quick recap of what is in the new 1.09 (CTO) bios and the previously available 1.06 version
