BIOSDECODE(8)                                  System Manager's Manual                                  BIOSDECODE(8)



NAME
       biosdecode - BIOS information decoder

SYNOPSIS
       biosdecode [OPTIONS]


DESCRIPTION
       biosdecode  parses  the BIOS memory and prints information about all structures (or entry points) it knows of.
       Currently known entry point types are:

       · SMBIOS (System Management BIOS)
         Use dmidecode for a more detailed output.

       · DMI (Desktop Management Interface, a legacy version of SMBIOS)
         Use dmidecode for a more detailed output.

       · SYSID

       · PNP (Plug and Play)

       · ACPI (Advanced Configuration and Power Interface)

       · BIOS32 (BIOS32 Service Directory)

       · PIR (PCI IRQ Routing)

       · 32OS (BIOS32 Extension, Compaq-specific)
         See ownership for a Compaq ownership tag retrieval tool.

       · SNY (Sony-specific, not decoded)

       · VPD (Vital Product Data, IBM-specific)
         Use vpddecode for a more detailed output.

       · FJKEYINF (Application Panel, Fujitsu-specific)


       biosdecode started its life as a part of dmidecode but as more entry point types were added, it was moved to a
       different program.
