Updating the BIOS:

1) Run WINUPTP.EXE as administrator.
2) Select 'Update ThinkPad BIOS' and follow the instructions on the screen.

   Follow the instructions on the screen to restart the computer.

If a previous version of X61/X61s SXGA+ BIOS is already installed on your machine, then WINUPTP.EXE may refuse to flash 
version 2.21-1.03. In this case you should do the following to update the BIOS:

1) Run WinPhlash.exe as administrator.
2) Click "Flash BIOS" button.
3) Don't interrupt flashing process (WinPhlash will reboot your machine at the end of procedure).
4) If you selected "BIOS update + CTRL-FN swap" version of this BIOS, then now you need to run WINUPTP.EXE (see above).



There is no BIOS update for X61/X61s which you can flash under 64-bit Windows. Lenovo recommends the following:
"If Windows Vista or 7 64-bit is already installed on your system, then you must use the bootable CD ISO format
of this BIOS update".
Bootable CD-image is included in this package.

Important note: When you boot from this CD, BIOS update will start automatically.
