• NAME
  
  biosdecode - BIOS information decoder
• SYNOPSIS
  
  biosdecode
  
• 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"

  "-h" ", " "--help"

  Display usage information and exit

  "-V" ", " "--version"

  /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).
