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:
o SMBIOS (System Management BIOS)
Use dmidecode for a more detailed output.
o DMI (Desktop Management Interface, a legacy version of SMBIOS)
Use dmidecode for a more detailed output.
o SYSID
o PNP (Plug and Play)
o ACPI (Advanced Configuration and Power Interface)
o BIOS32 (BIOS32 Service Directory)
o PIR (PCI IRQ Routing)
o 32OS (BIOS32 Extension, Compaq-specific)
See ownership for a Compaq ownership tag retrieval tool.
o SNY (Sony-specific, not decoded)
o VPD (Vital Product Data, IBM-specific)
Use vpddecode for a more detailed output.
o 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).
