Taken from the Manual Page
dmidecode is a tool for dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. This table contains a description of the system’s hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision.
Option 1: Getting DMI Type
[root@my-node1 ~]# dmidecode -t dmidecode: option requires an argument -- 't' Type number or keyword expected Valid type keywords are: bios system baseboard chassis processor memory cache connector slot
Option 2: DMI TYPES (From MAN Page)
DMI TYPES The SMBIOS specification defines the following DMI types: Type Information ──────────────────────────────────────────── 0 BIOS 1 System 2 Baseboard 3 Chassis 4 Processor 5 Memory Controller 6 Memory Module 7 Cache 8 Port Connector 9 System Slots 10 On Board Devices 11 OEM Strings 12 System Configuration Options 13 BIOS Language 14 Group Associations 15 System Event Log 16 Physical Memory Array 17 Memory Device 18 32-bit Memory Error 19 Memory Array Mapped Address 20 Memory Device Mapped Address 21 Built-in Pointing Device 22 Portable Battery 23 System Reset 24 Hardware Security 25 System Power Controls 26 Voltage Probe 27 Cooling Device 28 Temperature Probe 29 Electrical Current Probe 30 Out-of-band Remote Access 31 Boot Integrity Services 32 System Boot 33 64-bit Memory Error 34 Management Device 35 Management Device Component 36 Management Device Threshold Data 37 Memory Channel 38 IPMI Device 39 Power Supply 40 Additional Information 41 Onboard Devices Extended Information 42 Management Controller Host Interface
Option 3 – Using Keyword types
Keywords can be used instead of type numbers with --type. Each keyword is equivalent to a list of type numbers: Keyword Types ────────────────────────────── bios 0, 13 system 1, 12, 15, 23, 32 baseboard 2, 10, 41 chassis 3 processor 4 memory 5, 6, 16, 17 cache 7 connector 8 slot 9 Keywords are matched case-insensitively. The following command lines are equivalent: · dmidecode --type 0 --type 13 · dmidecode --type 0,13 · dmidecode --type bios · dmidecode --type BIOS
