UNIXPC: Can I have a RAM disk?

[Berentsen]

One of the Unix-pcs I use regularly has a DOS 73 Board that I very seldom use
(no it's not for sale).

If I ever get around to it I wanted to write a driver to
use the DOS 73 board as a mountable ram disk. 

Re: Ram Disk / Swapping (Paging) - Can't you can lock the ram disk in memory?
( using plock(2)  ? )
In any case, the unix pc does demand paging on an as needed basis. 
If you have more memory than you normaly use, (with 2+ meg on a single 
user system I rarely do any paging)
a ram disk should be a big performance boost.(?)
