If it's IC data sheets you're looking for, webulate to: http://www.amd.com/products/npd/techdocs/techdocs.html Bring a PDF reader, you'll need it. I've given the register-set for the 79C970A a cursory reading and there seems to be some notion of a software-style setting that can be used to make the chip behave like previous AMD Ethernet chips. My first thought was that maybe the Hitachi BIOS is doing some of the chip setup, but I don't understand what it would do that would let the lnc code work with the device-as-ISA-unit work but not as-PCI-unit. And I still don't get this: >As far as I can tell, there's no support for using the Hitachi's >internal PCI lance board in native PCI mode, so the card can only be >used in ISA emulation mode.
