Not sure how in depth of a response you will need. However, here is
basically how it works. Both sides of a connection will try to
auto-negotiate to the highest speed that they support. They step down
until an agreed upon speed can be found at the highest common
denominator. IF one side doesn't support autonegotiation, it will not
work with the other side in the negotiation process, and normally this
means that the host that IS set to auto-negotiate has no choice but to
assume the worst and will normally pick its lowest speed setting.
Normally you will end up with a 10Mbps half duplex connection on the
auto-negotiated host. If they two don't coincidentally match up, you
end up with lots of collisions and errors etc. in the best case, in the
worst case - you don't establish a connection at all.
