36 Chapter 2Using DMIToolsThe DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM to be used in the DMIpool for hardware management.When the BIOS displays Verifying DMI pool data it is checking that the table correlates with the hardwarebefore 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.Read DMI Information from MemoryInput:dmitools /rOutput:Manufacturer (Type1, Offset04h): AcerProduct Name (Type1, Offset05h): TravelMate xxxxxSerial Number (Type1, Offset07h): 01234567890123456789UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxAsset Tag (Type3, Offset04h): Acet AsstagWrite Product Name to EEPROMInput:dmitools /wp AcerWrite Serial Number to EEPROMInput:dmitools /ws 012345678901234567894 ).
