Dmidecode reports information about your system's hardware as
described in your system BIOS according to the SMBIOS/DMI standard .
This information typically includes system manufacturer, model
name, serial number, BIOS version, asset tag as well as a lot of other
details of varying level of interest and reliability depending on the
manufacturer.
This will often include usage status for the CPU sockets, expansion
slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O
ports (e.g. serial, parallel, USB).
DMI data can be used to enable or disable specific portions of
kernel code depending on the specific hardware. Thus, one use of
dmidecode is for kernel developers to detect system "signatures" and
add them to the kernel source code when needed.
Beware that DMI data have proven to be too unreliable to be blindly
trusted. Dmidecode does not scan your hardware, it only reports what
the BIOS told it to.
