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).
