This package updates the basic input/output system (BIOS) on all ThinkCentre M90, M90p, ThinkStation E20 and ThinkServer TS200v 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.

• If you prefer to create a bootable CD to update your BIOS, view 5jj964usa.txt.

Attention: Do not under any circumstance power off or restart the system during the Flash update procedure. Doing so will critically damage your system.

1. Changing system information using the USB drive BIOS Package

   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]

   /h	Show help messages.
   /rsmb	Preserve all SMBIOS structures.
   /ncb	Program all non-critical blocks
   /clr	Clear BIOS settings.
   /ign	Ignore BIOS version check.
   /sn:nnnnnnn	Update system serial number (up to 20 characters).
   /csn:nnnnnnn	Update chassis serial number (up to 20 characters).
   /mtm:nnnnnnn	Update machine type and model number (up to 20 characters).
   /tag:nnnnnnn	Update system asset tag (up to 25 characters).
   /uuid	The flash utility will generate an Universally Unique Identifier (UUID), replacing the one that is currently in the system.
   /logo <filename>	Change logo. The size of logo file after compression should be less than 8KB (the size of compressed logo file is displayed on the screen during the processing).
   /cpu	Update CPU microcode.
   /reboot	Automatic reboot after all requests done.
   /pass:nnnnnnn	Input current system password.

   • 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.

2. Changing system information using the Flash from Operating System version of the BIOS update

   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]

   /h	Show help messages.
   /rsmb	Preserve all SMBIOS structures.
   /ncb	Program all non-critical blocks.
   /clr	Clear BIOS settings.
   /ign	Ignore BIOS version check.
   /sn:nnnnnnn	Update system serial number (up to 20 characters).
   /csn:nnnnnnn	Update chassis serial number (up to 20 characters).
   /mtm:nnnnnnn	Update machine type and model number (up to 20 characters).
   /tag:nnnnnnn	Update system asset tag (up to 25 characters).
   /uuid	The flash utility will generate an Universally Unique Identifier (UUID), replacing the one that is currently in the system.
   /logo <filename>	Change logo. The size of logo file after compression should be less than 8KB (the size of compressed logo file is displayed on the screen during the processing).
   /cpu	Update CPU microcode.
   /reboot	Automatic reboot after all requests done.
   /pass:nnnnnnn	Input current system password.

   • 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.
     flash2.exe /logo:myfav.bmp

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