I've searched the forum and all I've found was that it should work by default. The ethernet hardware simply isn't recognized (ifconfig and so on) - so it seems. I've installed 10.5.1 (Kalyway release) on a Toshiba Tecra S2 (latest BIOS, all HW working properly with Linux and Windows).
As wireless lan cannot be used in encrypted mode, this would be my only option to connect to the internet. So - any suggestions? I've double checked the given hardware - there is an Yukon/Marvell LAN-chip installed with the internal name "88E8053". Maybe there is an option to (re-)activate the device?
Thanks in advance!
