So before I reply - please note that I think that HX is some pretty
amazing software; none of this was meant to be a dig at it.

Er.  Charles Sandmann is the author; while I will certainly agree that
he hasn't done a whole lot with it in a while, I'm pretty sure that
he does still maintain it.  He's certainly still active on the DJGPP
mailing list.

I'll put some thought in this... I agree that there's certainly not
any "nice" sort of answer.  In other universes I'd propose symlinking
CWSDPMI.EXE to HXDPMI.EXE, but without some changes to the command
interpreter that's not happening...

(Hey now, there's a proposal: what about support for DJGPP v2.04-style
symlinks in COMMAND.COM?)

But this discovery certainly surprised me, and I'm not sure that this
is the right answer... though I'll admit that I won't claim to know
off-hand what the right answer is...

If that is the only problem, just email me your program, and I'll patch 
it to look for the working extender. ;)

Apart from that, I second the opinion that it is a bad idea to rename 
things deliberately as this will usually make other things break when 
it's least expected. I've had a couple of occurrences of such which 
often turn into big headaches on my behalf, due to my middle name being 
"problem solver"... Well, at least at my workplace. I always get all the 
strange stuff on my desk ;)

Best regards,
Andre

Thats very bad reasoning. As bad as people who are using kernel
2037 because they like, say, the nice looking config menu better,
ignoring the fact that 2037 has several known real bugs. While HXDPMI
does work okay, it is definitely NOT the same as cwsdpmi. In parti-
cular, cwsdpmi has a configtool (for example to configure whether and
which swapfile to use) which will certainly not work with HXDPMI.

And as no docs for HXDPMI are included, how should I manage to
get a non-swapping *dpmi for DOSFSCK like that, for example...?
By the way, you should probably config the cwsdpmi default exe
for the distro to have swapfiles disabled anyway. Especially as
the distro can be used from cdrom...

Do include both HXDPMI (and other HXxyz tools) and CWSDPMI.

This output looks familiar to me.
Most likely it wasn't intentional. If it was, I'm pleased that there is so 
much faith in HX's DPMI host, but ...

- CWSDPMI and HDPMI are not fully compatible. Different cmdline options and
   different environment variables which they will check. And no documentation
   included for HDPMI ...
- why hide HDPMI under a different name? It is no trojan. And it is at the
   very least confusing, if not more.

So, I'd say that's a "no"...
Why is there something that's not really CWSDPMI being shipped with
FreeDOS with a filename that suggests that it's CWSDPMI?

It turns out to not be my problem, but it certainly kept me confused...
