Aha, I see. Yes, only after I "loadlow" LSL.COM (Link Support
Layer) and "loadlow" my nic things work again. So I conclude
that UMBPCI has a very different approach which does not 
raise all these implications but at the price that it is very chipset
dependent, where EMM386 follows a generic line (aiming
hardware independence) but having to fullfill far more issues
(VDS, DPMI/EMM/XMS memory pooling, etc.)
 
The thing is that network clients plus drivers are usually used 
as a ground layer and not as the end goal, so I try to be 
cautious with resources. Many applications that need to surf
on a network client (Citrix ICA for DOS, Arachne, Powerquest
Image, etc...) can be quite hungry for conventional memory.

Yes, that is a nice trick.
