Tried this driver on my ancient GA-EP45-DS3 and it seems to work a lot better than the lnx2mac driver I was using previously.
Actually my ethernet worked fine (out of the box) under 10.5 and 10.6. Installing 10.7 on a different disk required a driver and it also somehow killed the ethernet functionality on the SL partition, and I had to install lnx2mac driver on both.
Anyway thanks for this driver, it works great in a 32-bit kernel (some hardware I'm using limits me to 32-bit).
edit - I spoke too soon... the driver worked great until a reboot. Now the DHCP doesn't work properly (gets some random address) and although I can set things manually, it doesn't connect to the network.
The chip is a Realtek 8111C - it has 2 of them in fact, with identical results on both
So anyone know why this would work on install, but then stop working completely?
