UNIXPC: Can I have a RAM disk?

[Todd Day]

I've noticed in the manuals that you can't get 4 MB of RAM into
a unixpc using a COMBO board at 1 1/2 MB plus a 1/2 MB card.
Can this be done?  (I think I recall someone talking about
modifying the 1/2 MB card... please email me those instructions
if anyone has them).

Actually, what I'm really after is a 1/2 MB RAM disk.  I'd like
to prevent UNIX from knowing that I have the extra card and write
a RAM disk driver (maybe mount at /fast).  Anyone done this?

Actually, what would really be nice is to get your machine to get
the full 4 MB and THEN add yet another 1/2 MB RAM card for a RAM
disk, but I think this can't be done.  Any ideas?
