Which ethernet cards work with picnic?
I use a NE 2000 compatible ISA ethernet card with a Realtek 8019 chip in 8-bit mode. Your card should be somehow similar to mine: • ISA – probably you know ISA, the Industry Standard Architecture. Most computers had ISA slots, but nowadays it is mostly replaced by PCI. The ISA bus protocol is quite simple and therefore a good choice when interfacing with a PIC. Your card has to be an ISA card in any case. • 8 bit mode – ISA supports 8 bit mode as well as 16 bit mode. As the PIC is a 8 bit microcontroller we want to use the 8-bit mode of course. If you have a look at a 16-bit ethernet card you’ll see that it’s connectors are splitted into two groups. The smaller one is only used in 16-bit mode – normally, the NIC looks on power up if the second group is connected and chooses thereupon the operation mode. I don’t know if all the NICs support 8-bit mode but I guess they do so. Your NIC has to support 8-bit mode in any case. • NE 2000 compatible – this is a common term in the ethernet worl
