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, it was moved to a different program.

 

OPTIONS

-d, --dev-mem FILE

Read memory from device FILE (default: /dev/mem)

-h, --help

-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).
