You need to provide a driver disk for your harddrive controller, google or go to the manufacturer website to find linux drivers, once you have done that put them on floppy or usb disk. Re-start your fedora install, at the cdrom boot prompt type in 'linux dd' once Anaconda starts up it will ask you if you have any driver disks, this is the point where you slap that floppy in, tell Anaconda to look on fd0(default name) and it should then load your disk controller drivers, if you do not know how to create a driver disk: ->

That should get you in the right direction. :-)
