# Dell Precision A34: mapping SMBIOS tokens to BIOS setup fields

> A Dell Precision Tower 5810 and 7810 BIOS A34 investigation maps SMBIOS DA tokens to Dell setting IDs and AMI Setup bytes. It publishes per-model token tables, setting and token maps, setup-form options, and read-only token and byte-scanning tools. The author reports checking selected mappings against live reads and an NVRAM change.
