First is there a hard disk drive there????

If there is start with Tony's suggestion of checking the enable and
ready.
IF not, you'll need a drive maybe.

Do either of the floppies or their lights become active????

If they are it's looking for bootable media and there is none.

The other possibility is the drive(s) is/are disconnected or maybe plain
DOA.
