Upgrading problem

Upgrading problem

[Hossein Movahhedian]

   Dear All
   Hi,
   I have upgraded dosemu-1.0.1 to dosemu-1.2.2. The problem is
that the option $_emubat = "deb" does not work anymore. Furthemore
with $_xms = (10240) and $_ems = (10240) I receive the following
error message:{{{
ERROR: MAPPING: cannot get IPC shared mem (Invalid argument)

This may have the following reasons:
- you do not have IPC configured into the kernel
- the limits are to low for the amount of memory you requested
  in /etc/dosemu.conf. In this case either decrease the XMS/EMS/DPMI
  amount in /etc/dosemu.conf or increase the kernel limits such as
  'echo 67108864 >/proc/sys/kernel/shmmax'
}}}
Any help would be gratefully appreciated.

Thanks,
Hossein

Yes, but it is not a big problem.
You can use the /k option of
command.com in a SHELL= line of
a config.sys, to make it call the
alternative autoexec.bat.
Example:
SHELL=C:\COMMAND.COM c:\command.com /E:2048 /k autoxxx.bat
and it will use autoxxx.bat instead
of autoexec.bat.
Coupled with $_emusys, which still
works, you can retain all the former
functionality.

You can just ignore that message
(the consequences are that dosemu
may work slower as it will use the
file instead of IPC), or you can
upgrade your dosemu further (to
1.3.1 or CVS), where this error no
longer exist.

Yes, upgrading from 1.0.x have a
few rough edges as a lot of the
code was rewritten and some things
now work differently.
