If you’d like, I can:

Describes the memory array (e.g., “System RAM” or “Video RAM”). Version 2.6 added new error correction types.

smbios.epSlotVersion = "2.6"

Many automated asset tracking tools rely on reading these exact tables to log server inventory across older data centers.

This is a common point of confusion. There is a distinction between the and the BIOS Firmware Version .

To read SMBIOS data, the operating system must first locate the in system memory.
