Hello Bart,

Unfortunately - bad news, costing 1K of memory.
the current STACKS= default is (if nothing else given)
STACKS=8,128
in contrast, MSDOS has reportedly a default of STACKS=9,256
while the '8' shouldn't ever cause problems, I have seen recently the
'128' to cause problems.
Although it works most of the time, it made trouble with some more
recent hardware, with onboard (SATA) RAID.
this could be solved by either
stacks=9,256
or stacks=0,0
so I assume a stack overwrite in the RAID BIOS driver.
So I recommend setting the default to
stacks=8,256
which the user may overwrite as he likes.

for some reasons, I don't use EMM386 (some network cards cause trouble)
so I don't have upper memory, so there is no gain.
However the internal fnodes could go to HMA, then there would be a
real gain, even for me ;)
