That's odd.  Not to say "That's stupid."  The whole point of introducing IDE
was to make drive installation simple and not require the user to know the
details of the hardware, but they left this huge flaw in it?

The BIOS handles it fine.

I don't have four controllers here.  I have four IDE drives and only two
channels.  Would it be effective to put each HDD on its own cable, with a
CD drive as a slave?
