The ideal MCA adapter detection is done through the use of the
Programmable Option Select registers. Generic functions for doing
-this have been added in include/linux/mca.h and arch/i386/kernel/mca.c.

Everything needed to detect adapters and read (and write) configuration
information is there. A number of MCA-specific drivers already use
this. The typical probe code looks like the following:
In general, an interrupt must be acknowledged not only at the ICU (which
is done automagically by the kernel), but at the device level. In
particular, IRQ 0 must be reset after a timer interrupt (now done in
-arch/i386/kernel/time.c) or the first timer interrupt hangs the system.

There were also problems with the 1.3.x floppy drivers, but that seems
to have been fixed.
