This package updates the basic input/output system (BIOS) on all - ThinkCentre M83z, M73z and E73z systems.

BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard drives, and the keyboard. The BIOS is stored on a chip. Your computer uses flash BIOS, which can be updated through a program on a flash diskette so that you do not have to replace the BIOS chip to update the BIOS.

Note: Make note of any settings you have changed in the BIOS Configuration Utility. These settings may have to be re-entered after updating the BIOS.

Command Line Flashing Parameters

Option 1: DOS Flash Program Options

The default operation of the flash update program is a step by step dialogue with the user that presents choices and gathers responses from the user about which choices are desired.

In some situations (such as a large enterprise with many systems that need updating), it may be desirable to create a flash update image that requires no manual intervention to perform an update operation. This can be done by modifying the batch file (autoexec.bat) calling the flash program with the following command:

flash2.exe [option1] [option2] ... [optionX]

[OPTIONS]

• The following example shows how to update system asset tag number to "1234567" use command line:
  wflash2.exe /tag:1234567
• The following example shows how to update BIOS and update system asset tag number by one command:
  wflash2.exe bios.rom /tag:1234567
• The following example shows how to change the power-on logo.
  wflash2.exe /logo:myfav.bmp

Note: A flash update image using these program options should be tested carefully before widespread usage.

Option 2: Windows Flash Program Options

The default operation of the flash update program is to use the graphical user interface provided by the AFUWINGUI program. You can also run the program from a DOS command box (with Administrator privilege) by running "flash.cmd". Before running the "flash.cmd", please change the command line to the options you need. The command is:

wflash2.exe [option1] [option2] ... [optionX]

[OPTIONS]

• The following example shows how to update system asset tag number to "1234567" use command line:
  flash2.exe /tag:1234567
• The following example shows how to update BIOS and update system asset tag number by one command:
  flash2.exe bios.rom /tag:1234567
• The following example shows how to change the power-on logo.
