Hi Geert,

> Is it possible to detect the presence of Atari ROM port adapters?

That depends - what happens if you read from the ROM port with nothing
attached? I'll have to try. From memory, when I accidentially disconnected
the ROM port adapter, the EtherNEC module just got stuck and required a
reload. No kernel panic or other errors (tx timeouts aside). So I guess a
simple read test is not going to cut it. I'm not sure whether we can use
ARAnyM to check this - should accessing an empty ROM port generate a
kernel bus error, and will ARAnyM do this? Petr?

Something akin to the ISA ethercard probe should work, though. Is there
some way to explicitly test for presence of _any_ ISA card in a given
slot, or at a given IO address?

The conflict is with Q40, right? Do these boxes also have a ROM port?
Otherwise we could fix that by using something from the bootinfo, or make
it depend on the precise kind of Atari model detected in atari/config.c
