Dmidecode 명령어로 하드웨어 정보 보기 !
하드웨어 정보가 필요한 상황이야 여러가지로 많으니 어떻게 확인하는지 알아보자 ~
Dmidecode 도구는 DMI (일부는 SMBIOS라고도 함) 테이블을 읽어 데이터를 가져오고 하드웨어 세부 정보, 일련 번호 및 BIOS 버전, 프로세서 등과 같은 유용한 시스템 정보를 사람이 읽을 수있는 형식으로 표시합니다. dmidecode 명령을 실행하려면 루트 권한이 필요할 수 있습니다.
1. Demidecode의 기본 출력
아래는 Demidecode 명령 샘플 출력입니다.
# dmidecode 2.11 SMBIOS version fixup (2.31 -> 2.3). SMBIOS 2.3 present. 45 structures occupying 1642 bytes. Table at 0x000E0010. Handle 0x0000, DMI type 0, 20 bytes BIOS Information Vendor: Phoenix Technologies LTD Version: 6.00 Release Date: 12/06/2006 Address: 0xE78A0 Runtime Size: 100192 bytes ROM Size: 64 kB Characteristics: ISA is supported PCI is supported PC Card (PCMCIA) is supported PNP is supported APM is supported BIOS is upgradeable BIOS shadowing is allowed ESCD support is available USB legacy is supported Smart battery is supported BIOS boot specification is supported2. DMI 유형을 얻는 방법
DMI ID는 시스템의 특정 하드웨어 정보를 제공합니다. ‘-t’또는‘–type‘및‘Id‘옵션이있는 Dmidecode는 정확한 정보를 제공합니다. Id 6은 메모리 모듈 정보를 제공합니다.
