The dmidecode utility will display the SMBIOS (System Management BIOS) or the DMI (Desktop Management Interface) table. It can be very useful to determine your current hardware and other good information.<\/p>\n
To display type options:<\/p>\n
# dmidecode -t
\nType number or keyword expected
\nValid type keywords are:
\n bios
\n system
\n baseboard
\n chassis
\n processor
\n memory
\n cache
\n connector
\n slot<\/p>\n
Here is an example:
\n# dmidecode -t processor
\n# dmidecode 2.9
\nSMBIOS 2.3 present.<\/p>\n
Handle 0x0400, DMI type 4, 35 bytes
