How do you turn on the video when you can not see it? - Off topic

[Gary E. Masters]

A librarian associate has a Compaq computer with video on the mother board.
 He was trying to get a new video card to work and turned off the system
video at the BIOS setup.  Now he can not see anything on his monitor to
turn the video back on.  Is there a way to reset the configuration without
seeing what is on the screen?  Perhaps a keyboard sequence or so
manipulation of the bios chip?

I know this is off topic, but we don't know where to seek information
wiothout a major expense.  

Thanks,

Gary Masters
