[CentOS] Linux boot floppy to install over net

With all this going on, it seems to me there MUST be a floppy image 
that will load the minimum shell (including PCMCIA drivers!) and all 
over-the-net installs (HTTP, FTP, of NFS).

That would really help on one old notebook I have.

Oh, and of course this is for CentOS 4.2!
