But emulation is still needed for SMSW, right?
Likely so.
If you want, I can enable the logging of this command
and see if it is used by some of the DOS programs I have.
It would be great if you could do that, if you don't mind.
OK, scheduled to the week-end.
I'll let you know.
OK, done the testing.
It appears smsw is used in v86 by windows-3.1 and dos4gw
at the very least, and these are the "major" apps. So doing
without a fixup in v86 will not go unnoticed. Unfortunately
this also means that KVM-vm86 should be properly tested.
I have also found a weird program that does SGDT under
v86. This causes "ERROR: SGDT not implemented" under
dosemu, but the prog still works fine as it obviously does
not care about the results. This app can easily be broken
of course, if that makes any sense (likely not).
Thanks for inputs! Then it seems that we will need emulation for sgdt
and smsw.
I wouldn't claim we need an emulation of sgdt. One
or 2 exotic apps do not count much, considering the
overall small usage of dosemu and an easiness of
re-adding them to dosemu itself.
So if it makes any sense to not add it for vm86, then
please leave it omitted. However it seems Andy wants
an overall completeness here, lot let me just say I'll be
fine with either option.

  Perhaps sidt?
If only for overall completeness.
If it makes any sense to, please leave it omitted.

  sldt and str will not need emulation in either
protected mode or virtual-8086 mode. At a later stage I can look into
working in the syscall as Andy proposes.

I will also look into the kvm-v86 path for dosemu2.

It seems we have an agreement :) Do we?
Yes, fine with me.
