Ah... that makes sense. Thanks for the explanation.
That macio code sounds like quite a loss... here's
hoping more of it stuck in your head than you think!!

It's the built-in ethernet on the early iMacs, the beige G3,
and the B&W G3. iBooks use the gmac driver, which works fine.

I did have a look, and the code that enables the wireless part
of the macio chip was quite hideous, so I thought I'd wait a while
until I'd worked out something less of a hack. The 'lost' code
has some mods to the top-level macio code to allow underlying
devices to enable/disable themselves without poking around in
address space that didn't belong to them, and this would have
made the wireless attachment a bit simpler. More code to resurrect
from dusty memory :-)
later,
Peter.
