EPIA PCI slot

[Brian G. Rhodes]

Ron,

I was always under the impression that the BIOS should enable a device
(bus master) always.  And slaves would not be able to be set.  Some
devices set a capability which you can read this from to know whether the
device should be a master or not.

Why, or where, should the OS do it?  Driver?
