System Management BIOS (SMBIOS)

The SMBIOS provides numerous tables of data describing a computer's configuration. Available information includes items such as vendor name, BIOS version, installed components, CPU clock speed, etc.

The functions given in this section can be used to retrieve and parse the SMBIOS tables. Declarations of these functions and table entries (structures) are available in file Include\Rttsmbios.h and Libdel\Rttsmbios.pas.

Types RTSMSTR, RTSTRCNT, and RTSMHNDL used in some of the SMBIOS structures have special semantics. Values of type RTSMSTR are string indices. Function RTSMBIOSGetString can retrieve a pointer to the associated string. Values of type RTSTRCNT denote how many strings are appended to a structure. Function RTSMBIOSGetStringN can retrieve all such strings. Values of type RTSMHNDL reference another SMBIOS structure which can be located with RTSMBIOSFindHandle.

The SMBIOS structure declarations included in the following sections and in file Include\Rttsmbios.h correspond to version 2.4 of the SMBIOS specification. Older SMBIOS versions may only support a subset of the declared structure fields as later SMBIOS versions have appended data members to some structures. Function RTSMBIOSIsValid may be used to check if a particular structure member is supported.

More detailed information about the contents of the SMBIOS tables is available in the System Management BIOS (SMBIOS) Reference Specification, version 2.4, downloadable from http://www.dmtf.org/standards/smbios.
