epictetus / tsmbios

Library to access the SMBIOS using Object Pascal (Delphi, FPC).

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

• Source Full documented compatible with the help insight feature, available since Delphi 2005.
• Supports SMBIOS Version from 2.1 to 2.8
• Supports Delphi 5, 6, 7.
• Supports RAD Studio 2005-2010
• Supports RAD Studio XE-XE8
• Supports RAD Studio 10, 10.1, 10.2, 10.3, 10.4
• Compatible with FPC 2.4.0+
• Supports Windows, Linux.
• SMBIOS Data can be saved and/or load to a file.
• SMBIOS Data can be obtained from remote machines (via WMI).
