Truth: SMBIOS is discovery, not booting. You can run an NVMe drive on an SMBIOS 2.6 system if the BIOS has a UEFI option ROM or if you use a bootloader like Clover.
to support 64-bit address spaces and newer tech like USB Type-C or PCIe bifurcation, version 2.6 remains a vital legacy standard. Many "legacy" BIOS systems and early UEFI firmwares used this version to standardize how the Windows System Information (msinfo32) tool retrieves data. Impact on System Management
The phrase (likely the intended query) refers to a specific version of the System Management BIOS standard. This protocol allows the operating system to communicate with and retrieve detailed hardware information from your computer's motherboard. smbios version 26 top

The phrase "SMBIOS version 26 top" typically refers to the —the dominant specification for systems built between roughly 2009 and 2012. The number "26" is the textual rendering of the version "2.6". It is not referring to a "version 26.0" of the spec, but rather the second major revision with a minor revision of six. Truth: SMBIOS is discovery, not booting
It introduced key enhancements in power management, security, and hardware monitoring that set the stage for later UEFI standards 2.2.2. Top Features and Changes in SMBIOS 2.6
A 1-byte checksum ensures the entry point structure is valid and has not been corrupted during boot. Many "legacy" BIOS systems and early UEFI firmwares
Updated to support explicit voltage values instead of just bit-flags. It also added handles for identifying L1, L2, and L3 caches associated with specific processors. System Enclosure/Chassis (Type 3): Added fields for Bootup State Power Supply State Thermal State to provide better physical container reporting. Cache Information (Type 7): Expanded to include fields for Error Correction Type Associativity Memory Controller (Type 5): Enabled Error Correcting
