Ok, ok. Two comments made in < 5 sec = I'll change my autoexec :-)

Understand, and will do. Just wanted to keep everything identical between
things on my hdimage and the /dosc sequence until this gets resolved.

It has been for the 10 or so years I've had it. The only error behavior
I've ever seen from it is if I try to run two instances at once, say,
from a command line in pick-your-windows-version. The second instance
generates some kind of error (don't remember what it is, but could
generate it if you think would be helpful).

Whichever you prefer. I'm thinking it's not necessary to go back to
1.0.2.1, since it runs just fine in 1.2.0 from an hdimage - since the
last email I did in fact do this an compare the two log results, and
will post below for ref. But if you think there's a diff that can
be achieved going back to 1.0.2.1, let me know and I will.
This seems to have something to do with the difference between running
from hdimage and running from a real drive using redirection. In addition
to the observable behavior, I say this because, in one of the multi-MB
log files I got when I ran with debug option +a, there seemed to be a lot
of error-variety messages referring to lredir.
I also once again copied the artifacts from my hdimage to /dosc to ensure
equivalence (autoexec.bat, io.sys, msdos.sys, config.sys, command.com; and I
now have attrib from a Win95 boot disk, so I correctly reset the attribs on
the copied-over copies on /dosc). That had no effect.

Ok.
