swapfile-max.size

i have installed-beside 1.2 gb a second hdd 1 gb
exclusively for the swapfile on a pentium 133. it is working fine. normally i decide using fixed swapfile. in this case i have set min. to 100mb and let windows control. thats why it shows no max. size. is this the best setting of should i set 100/1000(max size of hdd) as min/max.?
i have 64 mb ram.
btw: it was very unwise if not stupid trying to install cache-cache\temp on that second drive. system crashed-i had to reinstall. i could do this combination(swapfile and cache-folder) but only on start-drive on a separate partition.
