There are jumper shunts on the board. They should be numbered 1 to 3 (don't
have one in front of me). No jumper = 0 MEM, 1 = .5Mb, 2 = 1 Mb, 3 = 1.5Mb.
that should do it for you. You may have other problems though if you have a
.5Mb RAM card, but that can be addressed with on of John Milton's HwNotes (I
have done this myself).
Hope that helps,
