the mix. Not sure why this happens but would love to get it fixed.


The technical reason is that windows performs a "warm" reboot where some
memory is left powered and not completely flushed resulting in a 'reboot' that
doesn't trigger a POST. Linux performs a "cold" boot where everything is
powered down and a complete reboot takes place, including dropping to the
level where the box will POST as part of the reboot.

Apparently the warm reboot leaves the nic in a state where it cannot accept
the linux network card driver when booting between windoze and Linux. Of
course, as you have found, going from Linux to windoze works just fine.

You may want to see if there is a bios setting that will force a cold reboot
between all OS's.
