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.
· 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
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).
