to complete this thread.... you can plot on 32bit system, java have to be installed and the pocminer downloaded for this method:
java -Xmx%useram%m -cp pocminer.jar;poclib/;poclib/akka/;poclib/jetty/* pocminer.POCMiner generate %numacc% %nonone% %nonces% %stagger% 4
-Xmx%useram%m is how much RAM your sysem has / or want to use
if dosn't work try -Xmx750m
%numacc% - is your nummeric account (NOT BURST-XXXX-...)
%nonone% - is the first nonce (for first plotfile almost 0)
%nonces% - is how much nonces you want to create / generate (one nonce is 256KB big)
%stagger% - the bigger, the better for mining... try %useram% like
4 - is how much threads u want to use (like CPU cores)
