Hello;
The PCI version of the e-series boards have pretty much the same features of the ISA version, the only difference is the bus.
So, you should be able to use the same acessories as you use with the AT boards.
Anyway, you can still try to install the AT boards with NT. The following link is a good step by step installation guide with some troubleshooting hints also. You just need to select the board and OS you are working at.

Hope this helps.
