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.

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).
