I've installed Leo with BrazilMac's method. Everything works just fine except My Realtek 8139 Pci card.
I added the card because my 775dual-vsta onboard LAN (ViaRhine) is just too buggy.
After 20 -30 minutes it looses connection, in system preferences it says connected but i cant connect to the network anymore.
I changed the kexts. tried different kernels but no succes.
Hardware is ok, i have 5 different rtl8139 card here all have the same problem, i change the pci slot too.
I am really bored of this problem, undere Tiger everything worked fine.
It would be very kind if someone knows a solution.
