So, I tried but without much luck
If I understood correctly:
- AS225 (r1) works on v1.3 but is compatible only with Commodore A2065 Ethernet cards;
- AS225 (r2) and other TCP/IP stack require v2.0+ but would be compatible with my Ariadne Ethernet card (which, by the way, requires v2.0+ to be installed);
- AmigaNOS works properly but may or may not be compatible with Ariadne Ethernet cards.
So, could anyone help me use AmigaNOS? Else, it seems that the only solution to get my A2000 on-line would be to upgrade its Kickstart...
