Simply put, DMA mode allows large chunks of data to be
transferred from IDE devices to system memory without
going through the CPU. PIO mode transfers tiny bits at a
time. If you bring up Task Manager while burning CD's
and compare the two transfer types, DMA mode uses a
very small amount of CPU time compared to PIO.
You should also set the transfer type to DMA Mode 2 in
your system bios. Sometimes it's listed as "PIO Mode 4/
DMA Mode 2", or "UDMA Mode 2".
