Using Dmitools - Acer Aspire 7560 Service Manual

Using DMITools

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 installed hardware components before sending information to the operating system
(Windows, etc.).
To update the DMI Pool, perform the following:
1. Boot to DOS.
2. At the prompt, enter dmitools 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. 20 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)
