Hi, indeed a very nice collection of probably small updates but
with big improvements in compatibility, even with binarified
leaves of lettuce :-). I hope I can test the new version soon...

Questions: New VCPI default is 256 MB, what was the previous
default? Can I assume that non-dumb DOS extenders alloc their 
memory through XMS rather than VCPI anyway, so most DOS extenders
will be able to use GigaBytes of memory no matter what the VCPI
MAX setting is? And: Do you mean 22 bytes of EMM386 local stack
or do you mean 22 bytes of DOS stack? I assume local stack, so
I expect no problems related to the change.

I do wonder which workaround style is used in our current 386
kernels, of course. A push/pop in execrh would mean more stack
footprint and slower device calls. Not using FS/GS at all in
the kernel would mean general performance degradation and bigger
kernel. In either case, I am happy to hear that we can soon test
without workarounds (as soon as Jeremy gets to disable
them, in general or for a test) and compare size and
performance (e.g. of CON output, as well as stack usage).


By the way, also a big thank you to Jeremy for his mysterious
386 mode Windows compatibility improvements. I would really
like to know what he changed and how...!
Yet I am still impressed that SHARE even makes classical
2035-something kernels DOS box compatible in Win 3.1 standard mode.
Possibly in combination with Japheth's DOSX variant. I did not
find the time to test whether it even works with stock DOSX. Shame
on me. All those big news and updates around and I did not test all
of them yet. Anyway, thanks a lot for all the updates.

(i.e. thanks Jeremy, Michael, Blair, Geraldo, probably also soon
Eduardo, Aitor, Henrique, David O'Shea of MEM... I should really
ask somebody to burn a CD of Blair's next ISO with all your updates :-))

Eric
