emacs 19.34 issues a blank line and returns to prompt,
24 gives sigsegv,
28 hangs,
26 is slow and can't find files

I think I was running 26 well a few months ago when I played with the non-DOS
partitions and somehow reset some environment variables.

The current behavior of 26 is the degradation that made me seek other
versions before, but 26 had worked well before

UEFI and AHCI are turned off. no himem.sys

Plus for some reason today tin/putty flies off before posting
and I may have posted redundantly (sorry)

Either it uses too much memory, or there's a problem with the compiler
regarding translating *nix to DOS environment.

Types of storage controller shouldn't be a problem.

This probably means you don't have a workable DPMI environment. What
is the OS you are using, and what does go32-v2 report when you run it
with no arguments?

MSDOS 6.22

There is a CWSDPMI inside emacs/bin

What is go32-vw?

Much Obliged

I am unlikely to be able to work on this for a week
(moving from NYC to Binghamton)

Is emacs/bin on PATH?

go32-v2 is a program that comes with DJGPP. Do you have djdev205.zip
installed? If not, I suggest to install it.

Really thanks for this. I had the hunch CWSDPIM or some driver.SYS was the issue.

Might there be problems with different versions of CWSDPMI or even with my
having too many copies in the path?

Should be (laptop is packed up)

Again much obliged

I'd suspect first some mis-configuration regarding the extended
memory. Emacs needs some minimal amount of it, and without that might
crash or simply exit. Running go32-v2 will tell how much memory DJGPP
programs can have on that system, and if the amount is too small, you
should look at your autoexec.nt and config.nt files for solutions.

You are welcome.

Because it isn't GNU. You will find it in current/v2/ instead.

Sorry, I forgot you were on plain DOS. There, the names of these
files are autoexec.bat and config.sys, respectively. Look there for
memory-related settings.

Starting to believe I have too many copies of CWSDMPI

(Been having trouble accessing CDROM and USB from DOS

GO32

go32/v2 version 2.0 built Oct 18 2015 09:41:08
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
well as v1 binaries (old makefiles). Put ahead of the old go32 in your PATH
but do not delete your old go32 - leave it in the PATH after this one.
Set GO32_V2_DEBUG=y in the environment to get verbose output.

Only the one that's first on PATH matters. Make sure it's the latest
version.

This should suffice.

Try not loading MSCDEX

Here, I'm missing

DOS=HIGH, UMB

and the line that loads HIMEM should not be commented out, I think.

Also, perhaps comment out the line that loads OAKCDROM.SYS.

If that doesn't let you run Emacs, I'm afraid I'm stumped. I don't
have plain DOS machine anymore, but the DJGPP Emacs runs OK for me on
Windows XP, FWIW.
