The SMBIOS-System Management BIOS specification defines data structures (and access methods) that can be used to read information stored in the BIOS of a computer.
By parsing this table it is possible to access information about the system and its capabilities.
AptioV DmiEdit is a tool that allows to read the SMBIOS tables and edit their content. In particular, the System Information table, containing data like the manufacturer of the system, the product name and the version can be extracted.
The utility is distributed in the following versions:
AmiDeWin32.exe for Windows 32-bit
AmiDeWin64.exe for Windows 64-bit
AmiDeLnx32 for Linux 32-bit
AmiDeLnx64 for Linux 64-bit
Type 1-System Information is the only one customizable. |
Type 2-Module Information is reserved to SECO. Do not write on it. |
The command /SM-Read/writeSystem Manufacture in Type 1 allows to write a new value just one time. An error will occurr from the second attempt onwards. |
