This package updates the basic input/output system (BIOS) on all ThinkCentre Edge 92, ThinkCentre M82, M92, M92p, ThinkStation E31 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.
- 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.
- Depending on the hardware configuration, some computer running on Windows 8 (64-bit) may require "OS Optimized Defaults" disabling in 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]
|/h||Show help messages.|
|/rsmb||Preserve all SMBIOS structures.|
|/ncb||Program all non-critical blocks|
|/clr||Clear BIOS settings.|
