NIC again

How can I access registers on a NIC (RTL8029AS), specyfication gives me
registers , but where are they, in some structure to write directly to
NIC memory or what?? I'm workig and writing for win2k.
Do I have to worry about PHY in my miniport driver??
Living it alone without managing would cause errors??

Read the hardware spec for this chip. Only it can give the answers.

Not sure about RTL8029. For many 10/100M NICs, the registers are mapped to
both memory and I/O space. It's accessible by memory dereference and/or I/O
instructions.

To access them in a ndis miniport driver, you need to:
1) obtain the resource ranges( i/o, memory, IRQ) by
NdisMQueryAdapterResources
2) make the accessible by NdisMMapIoSpace

Then you can access the registers by NdisReadRegisterUxxx functions.

PHY need to be properly setup in order the get the right
media/link/speed/plex config.

Good luck
