Disk space / upgrading OS

[Olwen Williams]

My development webserver (old Pentium II with assortment of drives) 
which I stumbled along and set up a few months ago has a space problem. 
 Details below.  I think I need to put /home on /dev/hdc and don't know 
the process to set it up

Second problem is that I set it up with Redhat 9 because it recognised 
the network card (Mandrake had problems)
I have FC2 Cds - am I likely to strike any problems?

Running fdisk shows me I have:
