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.).
Download and install Acer Drivers. If you are having problems with an Acer PC or another Acer device, the problem could be with your Acer Drivers. This often happens when users upgrade to a new Operating System and fail to update their Drivers so the Acer Drivers may be out of date or may have become corrupt over time. Software Acer has been hard at work developing software to make your digital life a breeze - in addition to our own offerings, we’ve partnered with the best in the business to bring you all the tools you’ll ever need.
To update the DMI Pool, perform the following steps:
- Boot into DOS.
- 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 Memory Input:
dmitools /r Output:
Manufacturer (Typel, 0ffset04h): Acer
Product Name (Typel, 0ffset05h): Aspire xxxx

4 ). Write UUID to EEPROM ( Create UUID from Intel WFM20.pdf ) Input:
dmitools /wu
5). Write Asset Tag to EEPROM Input:

dmitools /wa Acer Asstag NOTE: When using any of the Write options, restart the system to make the new DMI data effective.
Using the LAN MAC EEPROM Utility
You can use the MAC.BAT utility to write the MAC.CFG file to the EEPROM under DOS mode.
1. Use a text editor (for example: Notepad) to open the MAC.CFG file. You can see the MAC.CFG contents as below:
Title= HAC Address byte WriteData='001122334455' Startfiddr=7fi WriteLeng=ö KeepByte=0
WriteData = '001122334455' StartAddr=7A WriteLeng=6 KeepByte=0
MAC value MAC address MAC value length don't care
2. In DOS mode, run the MAC.BAT file to write MAC values to eeprom.
C : hflOmac . bat C:l1ftOeeproM u MAC.cfg Progress —> N Write Data to EEPROM OKff
