Hogyan nézzük meg a hardver összetételét a dmidecode programmal.
A dmidecode program segítségével számítógépünk hardveréről kapunk igen részletes információt. Azon kívül hogy megtekinthetjük a jelenlegi konfiguráció összetételét, megtudhatjuk a rendszer által maximálisan támogatott konfigurációt is.
Először nézzük át a man oldalt:
man dmidecode
A dmidecode parancs áttekintése
A parancs kimenete számos rekordot tartalmaz a DMI táblából. A felépítése követekező:
- Rekord fejléc: Azonosító (record id), DMI típus (dmi type id), Méret (record size)
- Rekord érték(ek): (több soros adatok)
- record id: egyedi bejegyzés azonosító
- dmi type id: Bejegyzés típusa, pl. BIOS, Memória, stb. (vagy 0, 1, 2, -39 ig)
- record size: Bejegyzés mérete a DMI táblába
Lássunk egy példát:
dmidecode
# dmidecode 2.9 SMBIOS 2.5 present. 26 structures occupying 1259 bytes. Table at 0x000FB180. Handle 0x0000, DMI type 0, 24 bytes BIOS Information Vendor: American Megatrends Inc. Version: 080014 Release Date: 03/11/2008 Address: 0xF0000 Runtime Size: 64 kB ROM Size: 512 kB
ezek szerint itt a 2.9 verzió fut és 26 bejegyzés azonosító található a DMI táblába.
Az információkat lekérhetjük típus szerint, számmal megadva a kért típust vagy szöveggel megadva egy típus csoportot. A típus számokat megkapjuk a man oldalban.
Kulcsszó fordítás típusai ------------------------------ BIOS BIOS 0, 13 system rendszer 1, 12, 15, 23, 32 baseboard alaplap 2, 10 cahsis ház 3 processor processzor 4 memory memória 5, 6, 16, 17 cache gyorsítótár 7 connector csatlakozó 8 slot foglalat 9
például nézzük meg a BIOS információkat:
dmdidecode -t BIOS
# dmidecode 2.9 SMBIOS 2.5 present. Handle 0x0000, DMI type 0, 24 bytes BIOS Information Vendor: American Megatrends Inc. Version: 080014 Release Date: 03/11/2008 Address: 0xF0000 Runtime Size: 64 kB ROM Size: 512 kB Characteristics: ISA is supported PCI is supported PC Card (PCMCIA) is supported PNP is supported BIOS is upgradeable BIOS shadowing is allowed Boot from CD is supported Selectable boot is supported EDD is supported Print screen service is supported (int 5h) 8042 keyboard services are supported (int 9h) Printer services are supported (int 17h) ACPI is supported USB legacy is supported Smart battery is supported BIOS boot specification is supported Targeted content distribution is supported BIOS Revision: 8.14 Handle 0x000E, DMI type 13, 22 bytes BIOS Language Information Installable Languages: 1 en|US|iso8859-1 Currently Installed Language: en|US|iso8859-1
Ezeket az infókat lekérhetjük külön külön is
dmidecode -t 0

Thank you
One of the most acclaimed and loved tenors of all time, Luciano Pavarotti celeb networth post was an Italian operatic tenor who during the late part of his career crossed over into popular music. He made numerous recordings of complete operas and individual arias, gaining worldwide fame for the quality of his tone, and eventually established himself as one of the finest tenors of the 20th century, achieving the honorific title "King of the High Cs".
As one of the Three Tenors, who performed their first concert during the 1990 FIFA World Cup before a global audience, Pavarotti became well known for his televised concerts and media appearances. From the beginning of his professional career as a tenor in 1961 in Italy to his final performance of "Nessun dorma" at the 2006 Winter Olympics in Turin, Pavarotti was at his best in bel canto operas, pre-Aida Verdi roles, and Puccini works such as La bohème, Tosca, Turandot and Madama Butterfly. He sold over 100 million records, and the first Three Tenors recording became the best-selling classical album of all time. Pavarotti was also noted for his charity work on behalf of refugees and the Red Cross, amongst others. He died from pancreatic cancer on 6 September 2007.
