that was a pretty odd problem.....hmm...
but DMA is Direct Memory Access. the Drive can send data directly to the main
memory rather than sending the data to the CPU first which will slow down
throughput (bad for watching DVDs and writing to hard drives and CD-RW etc)
and the 32 bit i/o will let you take advantage of your full PCI buss (which
is 32 bit unless you have high end hardware..in that case it might be
64...but unlikely...dunno for other than i386 so YMMV)
