Probing for non-pnp ISA cards is definitely unreliable.
Maybe some of these drivers should need to be explicitly
enabled in the kernel config.
The config is set by the distributions, not always cluefully. Non PnP
ISA drivers won't autoload either as they have nothing to key off.
I hadn't realised how bad some of the 3cxxx cards were!
The 3c500/01 were the first PC ethernet card ever so very very old.
I thought the 'parallel tasking' was all about starting
to tx a frame while the host was still copting it to the
tx fifo (and rx copies before end of frame), not that
It was.
