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  dont
       really  care  about addresses) or not enough (because it doesnt follow
       pointers and has no lookup tables).
