Perhaps try and use a different Keyboard and see if the feature reappears.
Or try system restore back to when it worked?
Then reinstall the Keyboard and see if the feature is gone again.
I installed a Micro Innovations Keyboard that has some wonderful features but about the same time I lost the bars that flash across the bottom of the screen that allow you with a stroke of the F8 key to perform alternate methods of booting up. I particularly miss the option of "Last known Good Configuration". Could this keyboard have something to do with this malfunction or does someone have an idea on how I can get this back?
The computer is running XP Pro as the OS and has 512Mb of Ram I can't think of anything else I've changed except changing the keyboard. I've changed the logon methods to see if that would make a difference and it has not. The "Welcome" screen and the traditional logon both act the same and neither gives me a chance to stop the normal boot up.
Thanks in advance for your help. Jim
