to
change the boot sequence to HDD | CD ROM | LAN | Floppy.
Using DMITools
The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM to be used in the DMI
pool for hardware management.
When the BIOS displays
Verifying DMI pool data
it is checking that the table correlates with the hardware
before sending to the operating system (Windows, etc.).
To update the DMI Pool, perform the following steps:
1.
Boot into DOS.
2.
Execute
dmitools
. 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.
