Introduction

What is SMBIOS?

SMBIOS is a standards-based approach for hardware vendors to present and structure management data for consumption by OS and Management Applications. You can find more information here: http://www.dmtf.org/standards/smbios .

Basically, the system BIOS leaves a small table in memory that can be found by the OS after system boot. This table has a standardized format that can easily be parsed by application software.

Several Dell-specific hardware features, such as BIOS update, CMOS Tokens, SMI, hardware probes (temperature, fan, etc) are represented in the SMBIOS tables. Because of this, libsmbios has code to enable these features on Dell systems.

Libsmbios goals

  • Best-practice design principles
  • Best-practice code sharing
  • Extensible Access to SMBIOS Information
  • Ability to perform unit tests across multiple systems without using physical hardware
  • Centralized, data-driven exception handling for broken BIOS tables

To start out with, the focus is on the SMBIOS tables. In the future, we will provide $PIR, MPTABLE, RCI, RBU, and other tables as well.

Currently, full access to the SMBIOS table and its items is implemented.

Additionally, access and manipulation of Dell Indexed IO Token (type 0xD4) is implemented. This token is a vendor-extention SMBIOS structure which allows uniform access to manipulate the system CMOS to enable, disable, or otherwise manipulate normal BIOS functions or features. See: What are CMOS Tokens
