Using DMITools
The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM. 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 to DOS.
2. At the prompt, enter dmitools.exe 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)
