ssh into Proxmox and run the following command

This means that the current BIOS version is 1.02

You will also need to follow this guide https://williamlam.com/2025/07/quick-tip-updating-firmware-on-minisforum-ms-a2.html

I made the following changes

  • Since the MS-A2 does NOT have compatible TPM chip with ESXi, you can get rid of the pesky warning by disabling Trusted Computing and Secure Boot
    • Advanced->Trusted Computing ✅
    • Security->Secure Boot ✅
    • Advanced->AMD Overclocking->Precision Boost Override - CPU Boost Override->Enabled (Negative)->Max Boost-> 500 (per reader this is supposed to help with fan speeds but I have not observed the same) - ❌ - I could not find this setting.
    • Advanced->Hardware Monitor->Fan Mode->Auto ✅
    • Advanced->AMD CBS->SMU Common Options->TjMAX->78 (Huge thanks to Chris West’s resource on temperature fix) ✅
