2.7 — Sm Bios

| Feature | Impact | |---------|--------| | | Now includes PCI Express generation and link width – essential for GPU/SSD detection on older servers. | | Type 17 (Memory Device) | Adds “Configured Memory Speed” vs. “Current Speed” – helps debug RAM throttling. | | Type 32 (System Boot Info) | Boot status (e.g., “no bootable media”) stored directly. | | Type 41 (Onboard Devices) | Distinguishes integrated NICs/RAID from add-on cards, even when BIOS strings are unhelpful. |

While the DMTF would eventually release (which introduced a new 64-bit entry point structure for UEFI), version 2.7 remains the "gold standard" for the final generation of BIOS-centric systems before UEFI became ubiquitous. | Feature | Impact | |---------|--------| | |
