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, if was moved
       to a different program.

OPTIONS

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

       -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).
