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?

The reason I was not getting interrupts on devices in the pci slot on the EPIA is because they were not set to be bus masters, so they would never generate interrupts. A quick write to the command register fixed the problem. Command register is being set to 0x02. It should be set to 0x06. a 6 to 4.
Thanks for the catch. IIRC, I did have extra ethernet card working before.
PLEASE do not patch linuxbios to enable this.
thanks
