Rethat 7.2 (I may be off by a few tenths) and probably
others of that time shipped with the IDE driver defaulting
to using PIO rather than DMA.  It was pretty easy to miss
interrupts if you had a lot of disk activity.  (I had a test
program that would drop zillions of them.)

These are my opinions, not necessarily my employer's.  I hate spam.
