Hi Anton,
There are no PCI DAQ boards that are supported by the last version of NI-DAQ to support DOS, 4.8.0. To find a list of the boards that were supported by this version, you can refer to Chapter 2 of the user manual:

Unfortunately, most of these boards are now obsolete and all are ISA.
I would highly recommend upgrading your software to work in a Windows environment.
Regards,
Erin
