HDPMI32 and 16-bit protected mode (DOSX)

It is a little bit annoying that with HDPMI32 loaded I can't more run 16-bit protected mode programs like Borland pascal 7.0 (file BP.EXE) or command line compiler and its utilities from Delphi 1. (all are extended by RTM.EXE+dpmi16bi.ovl )
Firstly I thought that it is unavoidable limitation of loaded 32-bit DPMI environment but I remembered that winh Win9x I alse have 32-bit DPMI and still can without any problems run Borland pascal 7.0.
How to solve it? It is something what Japheth has to do or something I have to do?

Quick reply (until/if somebody more experienced answers). IIRC for Jason Burgon's GVFM, you have to load HDPMI16 first, then perhaps HDPMI32. Or you could try a host that supports both (e.g. DPMIONE). Win16 used 16-bit DPMI internally, I think, but others (e.g. CWSDPMI) never bothered supporting that.

The strategy mentioned by Rugxulo should still work.

Of course "one" could make a binary which is able to digest both 16- and 32-bit clients, but IMO this is way too much work concerning the rather "limited" amount of people who care about such a special issue.
