Using DMITools
0
The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM
(Electrically Erasable Programmable Read-Only Memory). 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 information to the operating system (Windows, etc.).
To update the DMI Pool, perform the following:
1. Boot to DOS.
2. Execute
Dmitools.exe
.
The following messages report to screen to confirm completion:
 dmitools /r ==> Read dmi string from BIOS
 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
 dmitools /wa xxxx ==> Write asset tag to EEPROM (max. 32 characters)
The following examples show the commands and the corresponding output information.
