Running a DOS program in Wine

jeffneedle · Post by **jeffneedle** » Sat Jun 09, 2012 12:17 am

I'm trying to run the Q&A database in Wine. I change to the QA
directory in terminal, type "Wine qa.com", and get this error:

err:dosmem:DOSMEM_MapDosLayout Need full access to the first megabyte
for DOS mode

I know this is some sort of DOS-type error. Any idea how to get past
it? Thanks.

I'm far from an expert, but if your Q&A db is truly a DOS program, not
a Windows program, it needs to run in DOSBox. WINE is for Windows
programs, of any vintage, but not DOS. I have both kinds of programs
on my PCLOS machine here, and they both work pretty much as
expected, altho not perfectly--I lost my full-screen Pinball (WINE) and
I don't know how to fix it--it used to work right. But other WINE routines
work OK, and DOS programs in DOSBox work OK also. You can even
have your old text-only BASIC, Turbo Pascal, Eureka, NODES, and so
on in DOSBox. (NODES even produces some simple graphics.)

If your Q&A is really a Windows program, you may have to tell
WINE which kind of Windows it is--WINE can be set to mimic Win 95,
for instance, if you need it to. Or so I'm told.

Thanks! I responded privately to you -- saw that reply first.

I'll check out DOSBox and other solutions.

Try adding the following two lines:

# Sets a value required by WINE in DOS emulation mode.
vm.mmap_min_addr = 0

to the end of /etc/sysctl.conf

Thanks. I'll give it a try.

Any update on this. I'd be interested. Further please tell us your Wine version

Wine 1.3.28. It's the version that installed with Lubuntu, the light version of Ubuntu.

No more progress at this point. I've been occupied with other problems. Thanks for inquiring. When time allows, I'll report back.

That version is old and no longer supported. The current development release is 1.5.6.
