If you see "UEFI is supported" alongside SMBIOS 2.6, the firmware is modern but reports old SMBIOS version for OS compatibility.
Even with a well-defined standard, things can go wrong. SMBIOS-related issues can often be traced back to the system firmware (the BIOS or UEFI).
One of the most significant additions in version 2.6 was the introduction of and formal support for identifying system firmware characteristics related to virtualization.

It enabled tools like BigFix or IPMI management agents to consistently query hardware, reducing errors in Asset Management. If you see "UEFI is supported" alongside SMBIOS 2
: When a server suffers a memory failure, the OS error log correlates the failure to a specific memory address. Cross-referencing Type 16 (Physical Memory Array) and Type 17 identifies the exact physical slot containing the faulty DIMM.
Version 2.6 was a pivotal update that expanded the depth of hardware reporting. Key additions and changes include:
