Using DMITools
0
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)
