How the "low level stage" works comes pretty clear if you take a look at the
device driver development kit. It fact it is not much different from what we
are doing now. It is *very* important to implement it in that way to achieve
a reasonable channel access behaviour. Another advantage flexnet has over us,
is that it vitally has the CPU for its own. We are pretty close to that in
kernel mode. However, we have at least two *really* big advantages over
flexnet:
a reasonable memory buffer concept and very powerful subsystems for card
configuration (PCI) and low-level port access. We also have very nice debugging
tools (kdb et al.).
Writing a flexnet/16 device driver is a pain in the *ss.
