Ärende: dosemu 25 line error

there were a few lines that T had to change from the default DOSEMU config...
i'm trying to find them but yes...

  stty cols 80 rows 25

is in the script used to start DOSEMU and fire up the doors...

in /etc/dosemu/dosemu.conf, in the keyboard section,

  # $_layout = "auto"
  $_layout = us

and there was something about some memory setting somewhere but i can't locate
it... it wasn't in the DOSEMU settings but something else, IIRC...

the 59 line script T uses for all doors (better than duplicating everything
each time) follows... it logs everything to its own log file... the log file
should appear in the mystic logs directory where the other logs are located...

in mystic, the myemu script is called like the following examples which T runs
on the system... these are for L.O.R.D., Global War, Stack'em, Operation
Overkill II, and Falcon's Eye... the name given is the name of the door.bat
file that lives in mystic/doors along with x00.exe...

  ./myemu lord %3 /DOS
  ./myemu gwar %3 /DOS
  ./myemu stackem %3 /DOS
  ./myemu ooii %3 /DOS
  ./myemu falcon %3 /DOS

watch the wordwrap! myemu is 59 lines... config.sys is 14 counting the blank
one at the end... autoexec.bat is 11 counting the blank one at the end...


damn! i wish i could remember what and where that memory setting is/was that
had to be changed, too... it may have been in either /etc/sysctl.conf or
/etc/sysctl.d/... i'm thinking maybe something with the zero page memory
thing... it looks familiar but i don't see the original saved anywhere...

AHHHH... i found the note in the ~/.dosemu/boot.log that tells about it...

WARN: using non-zero memory base address 0x10f000.
WARN: You can use the better-tested zero based setup using
WARN: sysctl -w vm.mmap_min_addr=0
WARN: as root, or by changing the vm.mmap_min_addr setting in
WARN: /etc/sysctl.conf or a file in /etc/sysctl.d/ to 0.

it looks like T did this in the /etc/sysctl.conf file... at the very end...

oh, and here's an example of the myemu.log file...
