BIOS information decoder


biosdecode [Options]


biosdecode parses the BIOS memory and prints information about all structures (or entry points) it knows of. Currently known entry point types are:

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


-d,  --dev-mem FILE

Read memory from device FILE (default: /dev/mem)

   --pir full

Decode the details of the PCI IRQ routing table. Only full mode is supported.

-h,  --help

Display usage information and exit

-V,  --version

Display the version and exit




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).
