I don't know anything about Amithlon.. I assume its just a PC emulating an Amiga in software, right? If so, I would imagine any $1.99 PCI network card should work...? On my Amiga, the rtl_8139 card requires a driver in "Devs:networks" called rtl_8139.device. In "libs:" should be openpci.library. In "Envarc:openpci" should be rtl8139-n.config (where 'n' is the unit number of the card, 0 being the nic in the lowest physical pci slot, 4 being the max). If 'n' is not specified in the filename, 0 is assumed. The config file contains only one variable (that I am aware of..), and that is the connection speed. I think "1" indicates 100M FD, and "4" is Automatic. I might have those backwards, not sure.. Will check to confirm.
