| Approach | Pros | Cons | |----------|------|------| | | Stable, well-understood, compatible with legacy apps | No support for NVMe boot, persistent memory, large core counts | | Update BIOS/firmware | Gains SMBIOS 2.7 or 3.0 features | Risk if BIOS update fails; may not be available for old boards | | Replace hardware | Full support for modern standards | High cost; re-certification needed |

Introduced a "Sealed-case PC" enumeration for Net PC-type chassis.

SMBIOS 2.6 maintains the same discovery approach used by earlier 2.x versions; OSes search low memory for the anchor and validate checksums.
