Using DMITools
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. Read DMI Information from Memory:
Input:
dmitools /r
Output:
Manufacturer (Type1, Offset04h): Acer
Product Name (Type1, Offset05h): Easynote xxxxx
Serial Number (Type1, Offset07h): 01234567890123456789
UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-
xxxxxxxxxxxx
Asset Tag (Type3, Offset04h): Acet Asstag
2. Write Manufacturer Name to EEPROM
Input:
dmitools /wm Acer
3. Write Product Name to EEPROM
Input:
dmitools /wp AspireXXXX
4. Write Serial Number to EEPROM
Input:
