Hi,
In addition to CardReset, you'll need a TCP/IP stack. Check out
AmiTCP as this'll provide what you need for basic networking and includes the device files required for SLIP networking over RS232. If you want to use a PCMCIA network card, you'll also need either the
Prism drivers,
NE2000-compatible drivers or the
3Com drivers, depending on the hardware you have.
Transfer that lot over to the Amiga and install AmiTCP (don't be concerned it's a demo, it's fully functional aside from an enforced 2-second delay when you start the TCP/IP stack). Then install the relevant device driver.
AmiTCP and the device driver files contain full instructions on what to do, and if you're familiar with Linux networking, you should find it fairly straightforward.
Any questions, ask again on A.Org!
