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.

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).
