I found this directory /proc/sysvipc on my machine. Not actually knowing 
anything, I would guess that this is somehow related to the presence of 
that IPC thing. Do you have a directory with that name?

Did you take a look at /proc/sys/kernel/shmmax? For example, I get:

$ cat /proc/sys/kernel/shmmax
33554432

meaning 32 Mb shared memory. So, I need to have the total sum of $_xms, 
$_ems and $_dpmi to be less or equal to 32768 (kb) to fit in the shared 
memory, or I can do 'echo 67108864 >/proc/sys/kernel/shmmax' to get more 
shm (64 Mb, in that case) for dosemu.
