Yes, that is true. But I am using M$ for multibooting so someone has to be
blamed although not necessarily fairly. I chose the lesser of two evils, I
guess... but that does not include me! ;-)

Chris Shook of Redhat has contacted me and asked me to check the multi-booting
of his latest pre-release Alteros L2 NIC driver and there was a number of
facts that was uncovered during our correspondence.
1) Atheros bought Attansic and has improved the source code of
which Chris was given a copy.
2) Get rid of your Attansic L2 drivers and update to the latest
Atheros L2 driver for all OS's that needs it. Chris will soon upstream
his latest Atheros L2 driver. It should start in a few days or however
long it takes for the upstream cycle to complete.
Apparently, installing Attansic drivers and Atheros drivers in a multi-boot
environment caused some problems. The Attansic drivers does not always turn
on the link once turned off by an OS shutting down and another OS starting up
depending on which OS had the Attansic driver and which had the Atheros
driver when multi-booting.
I did step (2) above, tested several combinations of startup, shutdown
switching different OSes and the links all come up. This testing involves
only 2K, XP, and F8.
Kudos to Chris!
