For win 9x if you don't have a bootdisk: just hit F8 after your computer posts (makes the beep when it's done checking ram) you'll get a start up menu, and choose "Command Prompt Only" but finish with the steps you specified

c:>edit system.ini

change:
shell c:\litestep\litestep.exe
to:
;shell c:\litestep\litestep.exe
shell=explorer.exe

reboot, and your back to explorer, to switch to LS switch:

shell=explorer.exe
;shell c:\litestep\litestep.exe

to:

;shell=explorer.exe
shell c:\litestep\litestep.exe

HOWEVER: This is ALL in the manual.
