  A recent CD-ROM came with an ISA IDE interface card.  I used
it as an IDE controller for hard disk drives under NetBSD with no
problems.  I set wdc1 to 0x170 irq 15.  So the sound-card one
will probably work fine.

  Looking at the card, it contains only 4 chips -- 3 74LS
series 50-cent chips, and a simple PAL to generate enable
signals.  Is this all that is really needed for a `real' IDE
controller, or at least one that works with the PIO modes?
