Giunsa Pagkuha ang Impormasyon sa Hardware nga adunay Dmidecode Command sa Linux
Niini nga artikulo atong tan-awon kon unsaon nato paggamit ang Dmidecode command aron makuha ang impormasyon sa hardware sa bisan unsang sistema sa Linux. Pananglit kung gusto namon nga mag-upgrade sa usa ka sistema kinahanglan namon nga magtigum og kasayuran sama sa Memorya, BIOS ug CPU ug uban pa. Uban sa tabang sa Dmidecode nga mando mahibal-an namon ang mga detalye nga wala’y pag-abli sa chasis sa sistema. Ang Dmidecode command nagtrabaho para sa RHEL/CentOS/Fedora/Ubuntu Linux.
Ang himan sa Dmidecode nagbasa sa DMI (ang uban nag-ingon nga SMBIOS) nga lamesa aron makakuha og datos ug magpakita sa mapuslanong impormasyon sa sistema sama sa mga detalye sa hardware, serial number ug BIOS nga bersyon, Processor ug uban pa sa pormat nga mabasa sa tawo. Mahimong kinahanglan nimo ang pribilehiyo sa gamut aron mapatuman ang mando sa dmidecode.
1. Batakang Output sa Demidecode
Sa ubos mao ang Demidecode command sample output.
# 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 supported
2. Unsaon Pagkuha sa mga Matang sa DMI
Ang DMI Id naghatag kanamo ug partikular nga impormasyon sa hardware sa sistema. Ang Dmidecode nga adunay mga kapilian nga '-t' o '-type' ug 'Id' maghatag kanamo sa eksaktong infromation. Ang Id 6 maghatag kanato ug impormasyon sa Memory Module.
dmidecode -t 6 # dmidecode 2.11 SMBIOS version fixup (2.31 -> 2.3). SMBIOS 2.3 present. Handle 0x0009, DMI type 6, 12 bytes Memory Module Information Socket Designation: RAM socket #0 Bank Connections: 0 1 Current Speed: Unknown Type: EDO DIMM Installed Size: 1024 MB (Single-bank Connection) Enabled Size: 1024 MB (Single-bank Connection) Error Status: OK Handle 0x000A, DMI type 6, 12 bytes Memory Module Information Socket Designation: RAM socket #1 Bank Connections: 2 3 Current Speed: Unknown Type: EDO DIMM Installed Size: Not Installed Enabled Size: Not Installed Error Status: OK Handle 0x000B, DMI type 6, 12 bytes Memory Module Information Socket Designation: RAM socket #2 Bank Connections: 4 5 Current Speed: Unknown Type: EDO DIMM Installed Size: Not Installed Enabled Size: Not Installed Error Status: OK Handle 0x000C, DMI type 6, 12 bytes Memory Module Information Socket Designation: RAM socket #3 Bank Connections: 6 7 Current Speed: Unknown Type: EDO DIMM Installed Size: Not Installed Enabled Size: Not Installed Error Status: OK
Ang mosunod mao ang mga detalye sa matang sa DMI.
Type Information ---------------------------------------- 0 BIOS 1 System 2 Base Board 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
Imbis nga moadto sa 'type_id' mahimo usab nimo gamiton ang keyword nga adunay argumento nga '-t' sa dmidecode nga mando. Ang mosunod mao ang listahan sa magamit nga mga keyword.
Keyword Types ------------------------------ bios 0, 13 system 1, 12, 15, 23, 32 baseboard 2, 10 chassis 3 processor 4 memory 5, 6, 16, 17 cache 7 connector 8 slot 9
Pananglitan, aron makuha ang impormasyon sa Cache sa sistema, mahimo nimong ipatuman ang ubos nga sugo imbes nga Id 7.
dmidecode -t cache # dmidecode 2.11 SMBIOS version fixup (2.31 -> 2.3). SMBIOS 2.3 present. Handle 0x000D, DMI type 7, 19 bytes Cache Information Socket Designation: L1 Cache Configuration: Enabled, Socketed, Level 1 Operational Mode: Write Back Location: Internal Installed Size: 16 kB Maximum Size: 16 kB Supported SRAM Types: Burst Pipeline Burst Asynchronous Installed SRAM Type: Asynchronous Speed: Unknown Error Correction Type: Unknown System Type: Unknown Associativity: Unknown Handle 0x000E, DMI type 7, 19 bytes Cache Information Socket Designation: L2 Cache Configuration: Enabled, Socketed, Level 2 Operational Mode: Write Back Location: External Installed Size: 0 kB Maximum Size: 512 kB Supported SRAM Types: Burst Pipeline Burst Asynchronous Installed SRAM Type: None Speed: Unknown Error Correction Type: Unknown System Type: Unknown Associativity: Unknown
3. Unsaon Pagkuha sa Impormasyon sa Memorya
Unsaon nako pagkuha ang impormasyon sa Memorya sa sistema ug pila ka memorya ang gisuportahan sa sistema? Ang mosunod nga sugo nagpakita nga ang sistema makasuporta sa maximum 4GB sa RAM.
dmidecode -t 16 # dmidecode 2.11 SMBIOS version fixup (2.31 -> 2.3). SMBIOS 2.3 present. Handle 0x001D, DMI type 16, 15 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 4 GB Error Information Handle: Not Provided Number Of Devices: 4
Mubo nga sulat: Gikan sa lista sa keyword ang mga ID nga may kalabutan sa memorya mao ang 5, 6, 16 ug 17.
4. Unsaon Nako Pagkuha sa impormasyon sa BIOS?
Aron makuha ang kasayuran sa BIOS sa sistema, padagana ang mosunud nga mando nga adunay kapilian nga '-t'.
