biosdecode - BIOS information decoder

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).
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.
