Neither a Realtek 8019AS nor a 3Com Etherlink III 3C509 board are fully functional in my tandy 1000TL running DOS 6.22.
The Realtek card works fine with packet driver; after installing Microsoft network client 3.0 and installing the NDIS drivers, system hangs at "net initialize" in autoexec.bat. CTRL-ALT-DEL works. I SUSPECT I need to add something to the NDIS config file for my non-standard IO port/IRQ assignment on the card, the only parameters in the INF file are netaddress and adapterid, both of which I've tinkered with.
The 3C509 card is recognized but the configuration utility complains that no IO ports are available on my system, and the packet driver and NDIS driver both report there is no adapter found. I'm not sure the 3C509 adapters are 8-bit compatible, it may only be the 3C509-B cards that are? Works great in my 386SX box.
