Mere om DMI tables

DMI-tabellen beskriver ikke kun, hvad systemet i øjeblikket er lavet af, den kan også rapportere de mulige udviklinger, såsom den hurtigste understøttede CPU eller den maksimale mængde hukommelse, der understøttes.

Forstå BIOS ord

Syntax er:
dmidecode --type {KEYWORD / Number }
Du skal sende dmidecode efter nøgleord:

• bios
• system
• baseboard
• chassis
• processor
• memory
• cache
• connector
• slot

Alle DMI-typer du skal bruge med dmidecode –type {Number}:

For at få oplysninger om strømforbrug, skriv:

# dmidecode --type 39

For at få oplysninger om CPU informationer, skriv:

# dmidecode --type processor

# dmidecode -t System
