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?

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.(?)
