Swapfile

I would like to set up a permanent swap file on a PC that is always on in my 
house.  Not being a linux expert could some one assist me.

1) How big should I make it, disk space is not an issue

2) What is the sequence of commands (I use telnet) to the HD1K shell to 
instantiate the file.  I assume I just need to make a file in a shared network 
drive that the HD1K can see.  

3)What must the name of the swapfile be, if special, or can any name do as 
long as I am consistent in its reference

4) What HD1K file can I modify to cause the HD1K to re-initialize the swap 
file on every boot

5) What commands need I add to the startup file (4) to remake the swap file on 
every boot

Thanks in advance
