Du kan bruge f\u00e5 BIOS- og hardwareoplysninger med kommandoen dmidecode p\u00e5 Linux. Ingen grund til at \u00e5bne din server eller genstarte boksen. \u00a0dmidecode\u00a0er et kommandolinjev\u00e6rkt\u00f8j til at analysere BIOS-hukommelsen og udskrive oplysninger om alle strukturer. Du kan finde ud af mere information om din hardware s\u00e5som:<\/div>\n<\/div>\n

IPMI Device
\nType af memory og hastighed
\nChassis Information
\nTemperatur info
\nK\u00f8ling Device
\nElectrical Current Probe
\nProcessor og Memory Information
\nSerial nr
\nBIOS version
\nPCI \/ PCIe Slots og hastighed
\nSMBIOS (System Management BIOS)
\nSYSID
\nPNP (Plug og Play)
\nACPI (Advanced Configuration og Power Interface)
\nBIOS32 (BIOS32 Service Directory)
\nPIR (PCI IRQ Routing)<\/p>\n

I dette tip vil du l\u00e6re om afkodning af BIOS-data (dumping af en computers DMI) og f\u00e5 alle oplysninger om computer hardware uden at genstarte serveren.

Mere om DMI tables<\/h2>\n

DMI-tabellen beskriver ikke kun, hvad systemet i \u00f8jeblikket er lavet af, den kan ogs\u00e5 rapportere de mulige udviklinger, s\u00e5som den hurtigste underst\u00f8ttede CPU eller den maksimale m\u00e6ngde hukommelse, der underst\u00f8ttes.<\/p>\n

dmidecode \u2013 L\u00e6s biosdecode data i et l\u00e6sbart format.<\/h2>\n
Data leveret af biosdecode er ikke i et format, der kan l\u00e6ses af mennesker. Du skal bruge dmidecode-kommandoen til at dumpe en servers DMI (SMBIOS) tabelindhold p\u00e5 sk\u00e6rmen. Denne tabel indeholder en beskrivelse af systemets hardware komponenter samt andre nyttige oplysninger s\u00e5som serienumre og BIOS-revision. Takket v\u00e6re denne tabel kan du hente disse oplysninger uden at skulle s\u00f8ge efter den faktiske hardware. Lad os se nogle eksempler p\u00e5 dmidecode-kommandoer.<\/div>\n
