Hi,
I have problems with an accounting software for a hotel.
It refuses to run under DOSEMU but fails reporting a missing EMM. I have
loaded "ems.sys" within "config.sys", and xms, ems, and dpmi memory settings
in "dosemu.conf" seem ok to me.
Tracing the program's system calls with "dosemu -Da" showed me it tries to
detect an EMM by opening the 'files' EMMXXXX0, EMMQXXX0, $MMXXXX0, QMMXXXX0,
EMMXXXQ0 and QEMM386$. See the trace snippet below.

etc. etc.
Discovering that I checked how the DOSEMU "ems.sys" calls himself: It would
respond to " EMS", but not on anything of the above :(
My question now: Is it possible to change the name the "ems.sys" driver
reports?
Any help appreciated
