Using DMITools The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM to be used in the DMI pool for hardware management. When the BIOS displays Verifying DMI pool data it is checking that the table correlates with the hardware before sending to the operating system (Windows, etc.). To update the DMI Pool, perform the following steps: 1. Boot into DOS. 2. Execute dmitools. The following messages report to screen to confirm completion: • dmitools /r ==> Read dmi string from bios • dmitools /wm xxxx ==> Write manufacturer name to eeprom (max. 16 characters) • dmitools /wp xxxx ==> Write product name to eeprom (max. 16 characters) • dmitools /ws xxxx ==> Write serial number to eeprom (max. 22 characters) • dmitools /wu xxxx ==> Write uuid to eeprom • dmitools /wa xxxx ==> Write asset tag to eeprom (max. 32 characters) The following examples show the commands and the corresponding output information. Read DMI Information from Memory Input: dmitools /r Output: Manufacturer (Type1, Offset04h): Acer Product Name (Type1, Offset05h): Aspire xxxxx Serial Number (Type1, Offset07h): 01234567890123456789 UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx Write Manufacturer Name to EEPROM Input: dmitools /wm Acer Write Product Name to EEPROM Input: dmitools /wp Aspire 4540 Write Serial Number to EEPROM Input: dmitools /ws 01234567890123456789 Write UUID to EEPROM Input: dmitools /wu Write Asset Tag to EEPROM Input: dmitools /wa Acet Asstag NOTE: When using any of the Write options, restart the system to make the new DMI data effective. 40 Chapter 2
