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, if was moved to a different program.

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).
