Maybe it really is that rare to share the IDE interrupts with other
stuff?
IIRC, the legacy IDE interrupts were 14/15 and those were never shared.
Yes, non-shared 14/15 were the 95% common case for the longest time.
Sharing IDE interrupts within old-IDE worked FSVO "working", but the
interrupt probes were written for a non-shared interrupt, then hacking
into working for shared interrupts when PCI first starting showing up on
the scene.
