did you put your sys CD to have a try?
maybe your system is set to boot system from CD at first, so just try. if failed,
you don't need to wait to see such message
"pls enter F2, blah, blah, ", instead, enter F2 or F10 more times as long as the system is booting.
If your system is set to boot in fast way, it is hard to see the help message to enter the setups.
