FC5 network installation?

[Peter Horst]

I'm trying to install FC5 on a computer without a working floppy or 
cd-rom. This computer is currently running Debian stable, and is on a 
tiny little network with my WinXP laptop.  Someone on IRC was trying to 
explain how I can use Grub to do a network installation, but I'm not 
getting it. Does this involve installing some kind of PXE server on my 
other computer?  Is it possible to point Grub to a disk image on the 
same computer on which I'm trying to install the new OS? And if so, am I 
using an ISO image, or rather a set of unpacked files (kernel image, 
etc.)?  Thanks, hope this question rings a bell for someone.
