DESCRIPTION

13       biosdecode  parses  the  BIOS  memory  and prints information about all
14       structures (or entry points) it knows of. Currently known  entry  point
15       types are:
16
17       · SMBIOS (System Management BIOS)
18         Use dmidecode for a more detailed output.
19
20       · DMI (Desktop Management Interface, a legacy version of SMBIOS)
21         Use dmidecode for a more detailed output.
22
23       · SYSID
24
25       · PNP (Plug and Play)
26
27       · ACPI (Advanced Configuration and Power Interface)
28
29       · BIOS32 (BIOS32 Service Directory)
30
31       · PIR (PCI IRQ Routing)
32
33       · 32OS (BIOS32 Extension, Compaq-specific)
34         See ownership for a Compaq ownership tag retrieval tool.
35
36       · SNY (Sony-specific, not decoded)
37
38       · VPD (Vital Product Data, IBM-specific)
39         Use vpddecode for a more detailed output.

42       biosdecode  started  its  life as a part of dmidecode but as more entry
43       point types were added, if was moved to a different program.

BUGS

61       Most of the time, biosdecode prints too  much  information  (you  don't
62       really  care  about addresses) or not enough (because it doesn't follow
63       pointers and has no lookup tables).
