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 the table correlates with the hardware before sending to the operating system (Windows, etc.).

To update the DMI Pool, perform the following steps:

  1. Enter into DOS.
  2. Execute dmitools. The following messages show dmitools usage:
  • dmitools /r ==> Read dmi string from memory
  • 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 (Ignore String)
  • dmitools /wa xxxx ==> Write asset tag to EEPROM (max. 32 characters)

NOTE: The following write examples (2 to 5) require a system reboot to take effect
