biosdecode is a command line utility to parses the BIOS memory and prints information about all structures (or entry points) it knows of. You can find out more information about your hardware such as:
=> IPMI Device
=> Type of memory and speed
=> Chassis Information
=> Temperature Probe
=> Cooling Device
=> Electrical Current Probe
=> Processor and Memory Information
=> Serial numbers
=> BIOS version
=> PCI / PCIe Slots and Speed
=> Much more

biosdecode parses the BIOS memory and prints the following information about all structures :
=> SMBIOS (System Management BIOS)
=> DMI (Desktop Management Interface, a legacy version of SMBIOS)
=> PNP (Plug and Play)
=> ACPI (Advanced Configuration and Power Interface)
=> BIOS32 (BIOS32 Service Directory)
=> PIR (PCI IRQ Routing)
=> 32OS (BIOS32 Extension, Compaq-specific)
=> VPD (Vital Product Data, IBM-specific)
=> FJKEYINF (Application Panel, Fujitsu-specific)

In this tip you will learn about decoding BIOS data (dumping a computer’s DMI ) and getting all information about computer hardware without rebooting the server.
