Well, not always.  I was just playing around with an Everex Magic I/O
card the last couple of days.  In the manual, it tells you that you can
configure the serial ports to use IRQ 2.  But when you look at the
silkscreen on the board, you see it's labeled as IRQ 9.  Now, when I
use the board under UNIX, I tell the driver to use IRQ 9, and it works
fine.  Yet when I bring up Procomm under DOS, it won't even let me
enter 9 as the IRQ -- I have to enter 2.  So it seems there's still
some confusion in the hardware/software market over this.
