de0 recognized but not configurable

[Gary Aitken]

Pretty old.  It's a micron p200, pre mellinium.  1997?
I'm not sure what you mean by changing the BIOS setting for an irq.  Do 
some bios allow you to change irqs of add in boards? I don't see any way 
to do that in the Phoenix bios on this system.
I rearranged the boards and managed to get the irq for the de board at 
11, but the video driver was still at 15.  The de still wouldn't configure
