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 don’t really care about addresses) or not enough (because it doesn’t follow pointers and has no lookup tables).
