smbios [-BeOsx] [-i id] [-t type] [-w file] [file]
The SMBIOS image consists of a table of structures, each describing some aspect of the system software or hardware configuration. By default, smbios displays the entire contents of the current SMBIOS image. If the -s option is specified, smbios displays a summary of the structures that are present in the image. If the -w option is specified, smbios writes a copy of the SMBIOS image to the specified file. smbios can then be applied to the resulting file to display its content.
smbios attempts to display each structure and its content in a human- readable fashion. If smbios does not recognize a structure's type or content, the raw hexadecimal data for the structure is displayed.
Disable header validation for broken BIOSes. By default, smbios attempts to validate the SMBIOS header by verifying the anchor strings, header checksums, and version number. This option might be necessary when a BIOS has a non-compliant header.
Display the contents of the SMBIOS entry point rather than the contents of the SMBIOS structure table.
Display only the specified structure, named by its integer id.
Display obsolete structure types. By default, smbios elides output for structures whose type is marked as obsolete in the DMTF SMBIOS specification.
Display only a summary listing of the structure identifiers and types, instead of the content of each selected structure.
Display only those structures whose type matches the specified integer type, as defined the DMTF SMBIOS specification.
Write a copy of the SMBIOS image to the specified file and exit. The SMBIOS entry point is written to the start of the file with its structure table address set to the file offset of the structure table, and a new entry point checksum is computed.
Display raw hexadecimal data for the selected structures in addition to human-readable output. By default, hexadecimal data is only displayed if smbios cannot display human-readable output for the selected structures.
Specifies an alternate SMBIOS image to display instead of the current system's SMBIOS image.
Successful completion. All structures in the SMBIOS image were examined successfully.
A fatal error occurred, such as failure to open the specified file or device, or corruption in the image.
Invalid command-line options were specified.
Kernel SMBIOS image device. This device special file is used to export a snapshot of the current system SMBIOS image.

| Interface Stability See below. |
The command-line options are Evolving. The human-readable output is Unstable.
System Management BIOS Reference Specification (see http://www.dmtf.org)
Due to ambiguities in early revisions of the SMBIOS specification, this utility incorrectly interprets the first three fields of the system information UUID field as network-endian; the SMBIOS specification defines them as little-endian. The "UUID (Endian-corrected)" field has the correct value.
