BIOS Flash Utilities
The BIOS flash memory update is required for the following conditions:
• New versions of system programs
• New features or options
• Restore a BIOS when it becomes corrupted. 
Use the Phlash utility to update the system BIOS flash ROM.
NOTE: If you do not have a crisis recovery diskette at hand, then you should create a Crisis Recovery 
Diskette before you use the Phlash utility.
NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.
NOTE: Please use the AC adaptor power supply when you run the Phlash utility. If the battery pack does not 
contain enough power to finish BIOS flash, you may not boot the system because the BIOS is not 
completely loaded. 
Fellow the steps below to run the Phlash.
1.Prepare a bootable diskette.
2.Copy the flash utilities to the bootable diskette.
3.Then boot the system from the bootable diskette. The flash utility has auto-execution function.

If you key in the wrong HDD password three times, an error code is generated.
To reset the HDD password, perform the following steps:
1.On a different machine, run the HDD_PW.EXE file along with the error code generated. For example:
hdd_pw 15494 0
2.Select an option to generate upper case or lower case ASCII code for unlocking the HDD. 
3.Two strings are generated as output. Select and note down either one of the strings.
4.Reboot the machine with the locked HDD and then use either one of the strings as the HDD user 
password.

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.
Read DMI Information from Memory
Input: 
dmitools /r
Output:
Manufacturer (Type1, Offset04h): Acer
Product Name (Type1, Offset05h): TravelMate xxxxx
Serial Number (Type1, Offset07h): 01234567890123456789
UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Asset Tag (Type3, Offset04h): Acet Asstag
Write Product Name to EEPROM
Input:
dmitools /wp Acer
Write Serial Number to EEPROM
Input:
dmitools /ws 01234567890123456789
4). Write UUID to EEPROM (Create UUID from Intel WFM20.pdf)
Input:
dmitools /wu
5). Write Asset Tag to EEPROM
Input:
dmitools /wa Acet Asstag
NOTE: When using any of the Write options, restart the system to make the new DMI data effective.
