This is the link I used: https://dr.bee-link.cn/?dir=uploads%2FSER%2FSER9--AI-9-HX-370%2FBIOS
From the above note from support, the BIOS update is only for the Y-series SER9s right now, however another person tried the D on his Y and the system reported that BIOS was incompatible, nevertheless, be sure what you’re doing before applying a BIOS.
Your SN is on a sticker on the bottom but if you’re like me, and I know you are, you can use “sudo dmidecode” to retrieve your SN. Again, be careful because on mine, which is a Y-series, the serial number under “System Information” comes back as YHX37…… while under Base Board Information it reads D9DS0……. I believe that the “System Information” serial number is what you’re after.
The new BIOS is working out extremely well, on heavy games like Robocop Rogue City, the graphics are faster, smoother and clearer. Also I would occasionally be greeted with a solid green screen when changing resolutions or coming out of sleep but with the new BIOS and firmware, that hasn’t happened.
Thank you for the update gentle support entity, please make a note on the BIOS download page that there are Y-series and D-series SER9s and never the two should mix BIOS updates.
