NAME
     biosdecode - BIOS information decoder

SYNOPSIS
     biosdecode [OPTIONS]

DESCRIPTION
     biosdecode  parses  the BIOS memory and prints information about all struc-
     tures (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)

	 --pir full
	    Decode  the details of the PCI IRQ routing table.  Only full mode is
	    supported.

     -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).
