I've got my cabinet half built, and my computer half configured and somewhat assembled.  But the only OS I've got on hand is Win98 (not SE).  I see a lot of SE talk here.
I plan on running Mame+Mamewah.  What problems am I in for without SE?
PS: I did try Linux + advmame but finally gave up because of svgalib issues (and my ignorance).  My video card wasn't on the list...
