Hi Ben!
As long as there are OS/2 drivers available for your network cards, you
should be able to use the DRM disk dump.
Only a few cards are detected by the 'Automatically detect network card'
option, but you can add the drivers for your card manually. Check the
'Disaster Recovery Manager: Stand-alone Disk Image Dump and Restore Guide'
(GC35-0343), Chapter 3, page 11 and 14 for more information.
Kindest regards,
Eric van Loon
