BIOSDECODE(8)            (February 2007)            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. Cur-
          rently known entry point types are:

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

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

          +o SYSID

          +o PNP (Plug and Play)

          +o ACPI (Advanced Configuration and Power Interface)

          +o BIOS32 (BIOS32 Service Directory)

          +o PIR (PCI IRQ Routing)

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

          +o SNY (Sony-specific, not decoded)

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

          +o 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 differ-
          ent program.

     OPTIONS
          -d, --dev-mem FILE
               Read memory from device FILE (default: /dev/mem)

              --pir full
               Decode the details of the PCI IRQ routing table

          -h, --help
               Display usage information and exit

          -V, --version
               Display the version and exit

     FILES
          /dev/mem

     BUGS
          Most of the time, biosdecode prints too much information
          (you don't really care about addresses) or not enough
          (because it doesn't follow pointers and has no lookup
          tables).
