Just a nit, but it could save some wasted time.

The BIOS configuration utility for most ThinkPads is PS2, not PS. It is
a DOS tool, but will not work with WINE, DOSCMD, or any other DOS
emulator I have seen. You really need to make a DOS disk with he
executable on it.

If you have the Windows software that came on your system, PS2 is
available from the DOS command tool. Try 'PS2 ?' for a summary.
