This package updates the basic input/output system (BIOS) on all ThinkCentre M92z 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.
In most instances, you will need only one of the listed exe or iso files.
If you prefer to update your BIOS from within Windows, download 9njy48usa.exe.
If you prefer to update your BIOS with USB drive BIOS flash package , download 9njt48usa.zip.
If you prefer to create a bootable CD to update your BIOS, download 9nj948usa.iso.
Click the appropriate file link to download the file from the Web page.
When prompted, select a drive and directory in which to save the downloaded file, be sure to select a path that does not have a space in its name.
Installing the update
Follow the instructions provided in the corresponding txt file from above.
If you prefer to update your BIOS from within Windows, view 9njy48usa.txt.
If you prefer to create a bootable CD to update your BIOS, view 9nj948usa.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.
Command Line Flashing Parameters
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.
