The SMBIOS (System Management BIOS) is a standard developed by the DMTF. The information stored in the SMBIOS includes devices manufacturer, model name, serial number, BIOS version, asset tag, processors, ports and device memory installed.
The TSMBIOS libary allows access the System Management BIOS (SMBIOS) using the Object Pascal language (Delphi or Free Pascal).
Features
- Fully documented (XMLDoc), compatible with the Help Insight feature, available since Delphi 2005.
- Supports SMBIOS Version 2.1 to 2.8.
- Compatible with Delphi 5 through Delphi 11 Alexandria.
- Works with FPC 2.4.0 or later.
- Supports Windows and Linux.
- Can read SMBIOS data from remote machines using WMI.
