如何升级T43 44H的BIOS？
RT
IBM的网站是这样说的：
7. In the Open dialog box, specify the utility filename with the full path name where you stored ThinkPad BIOS Update Utility (e.g. C:\Temp\1YUJ11US.EXE) and then press the Enter key.
Note: For unattended update, specify the file name with options "-s -a -s". (e.g. C:\Temp\1YUJ11US.EXE -s -a -s) The BIOS is updated without any user interaction.
8. Follow the instructions on the screen.
Depending on the operating system configuration, restarting the operating system and rerunning this BIOS update utility may be required. In this case, the following message will appear on the screen. "DeviceIoControl() returns 2 Please restart your operating system and execute the BIOS or Embedded Controller update utility again."
Windows will shut down automatically and ThinkPad BIOS Update Utility screen appears.
9.Select Read this first from the menu and carefully read the information that appears.
10. Press the Esc key to return to the menu.
11.Select Update system program and follow the instruction on the screen.
Attention: Do not turn off or suspend the system until the update has been completed. If you turn off or suspend the system while the update is still in progress, the system board may have to be replaced.
After the update has been completed, the system is automatically turned off.
Do the following to make sure the BIOS is updated correctly.
12.Turn on the system.
13.While the "To interrupt normal startup, press the blue Access IBM button" message is displayed at the lower-left of the screen, press the Access IBM button.
14.Select Start setup utility. If you have set a supervisor password, the BIOS Setup Utility menu appears after you type in the password.
Verify the BIOS version and date.
15.Turn off the system.
