Miscellaneous Tools Using DMI Tools The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM and used in the DMI pool for hardware management. When the BIOS shows Verifying DMI pool data, it is checking that the table correlates with the hardware before sending it to the operating system (Windows, etc.). To update the DMI Pool, perform the following: 1. Boot from DOS. 2. At the command prompt, execute dmitools [argument] [string] with one of the following arguments: • /r ==> Read DMI information from memory • /wm ==> Write Manufacturer Name to EEPROM (max. 16 characters) • /wp ==> Write Product Name to EEPROM (max. 16 characters) • /ws ==> Write Serial Number to EEPROM (max. 22 characters) • /wu ==> Write UUID to EEPROM (ignore string) • /wa ==> Write Asset Tag to EEPROM (max. 32 characters) The following examples show the commands and the corresponding output information: 1.
