I just checked my machine and I'm running the Advantech PCA-6742 with 128 megs onboard with the Eva-X4300 cpu at 300Mhz. I also have a PCA-6743 which works but I'm using the PCA-6742 despite it not having floppy support as it has a compact flash slot onboard.
If you are hoping to use Windows 3.11 or Win98 for network support use the Microsoft LAN Manager Client (LANMAN) for DOS. It's basically a stand alone DOS workgroup client from Windows for Workgroups 3.11 era.

It appears Microsoft FTP no longer works... so a quick google found the MSCLIENT install disks here:
