This Winzip file contains most of the drivers for 1394 ethernet users. However, I still have not been able to locate (drci1394.sys) or (ntmaphlp.pdr). However, I did find a self extracting file at Microsoft, which, quite frankly I haven't opened yet) that may contain the missing files. It is a Win32 cabinet upgrade to Windows 98, and I believe it has all the 1394 files you will need contained within it. At least that is my hope. I'll find out when I get it opened up later.
The following files are found inside the driver download file.
