ServerWorks OSB4 locks solid if I access both IDE channels, and either
one has DMA enabled.  Current solutions: (i) abandon second channel,
(ii) use PIO, (iii) add Promise card, (iv) add 3ware card.

My machines use (i), (iii), and (iv).  I didn't test two devices on the
same channel, e.g. /dev/hd[ab]
