Well, yes and no. Some PCI slots are not capable of being bus masters
(don't know more details than that, but i've seen vendors say that
about some of their PCI slots), and if the BIOS does the right thing
then indeed, the OS setting it _does_ hurt something.
Of course, those cases should be few and far between (i hope).
