That's more or less true. There are really two problems:
1. The PCI-specific driver and HAL calls do not exist in the NDIS
wrapper that shipped with Windows NT 3.1.
2. Microsoft strongly recommended (and we listened) that developers
create NDIS 3.0 miniport drivers for Windows NT 3.5, Windows 95,
and beyond. The Windows NT 3.1 NDIS wrapper does not support
miniport network drivers.
The final Premium SDK/DDK that Microsoft shipped out to developers
included an NDIS 3.0 wrapper for Windows NT 3.1 that (in theory)
includes the API's for miniports. Developers can then use their
existing code base to build Windows NT 3.1 compatible drivers, then
install the new wrapper and get it to work.
Did Microsoft include FDDI miniport driver support in this special
wrapper?
Did Microsoft include the PCI-specific driver and HAL calls?
I don't really know the answer to either question at this point. In
any event, it may become a lot of extra work on our part to find out.
I'm hoping that the majority of Windows NT 3.1 customers will upgrade
to Windows NT 3.5 and make the issue moot. So far this seems to be
holding true.
