Of course there is an alternative to the OS/2 DOS session: DOSBox

Just for fun I did not install DOS/Win16 support when Installing
eC2.0RC6a recently and use DOSBox instead.

My DOS use is really limited to playing a few old games and DOSBox can
play those with sound - unlike OS/2 DOS sessions if using the Uniaud
driver.

Just for fun I have also installed Windows3.1 and 3.11 into DOSBox
sessions and they seem to work reasonably well.

I'm curious .. I downloaded a copy of this and it does open using a virtual
drive letter z:\ operation. That apparently has 640K of basic 'memory' for
this virtual DOS application.

Is there any way to get it to give me more than 640K like in a DOS-VDM OS/2
operation with either CGA or MONO memory for video?


You are going to have to dig through the docs or email the developers to get an answer to the above I think.


Also, is it possible to set it up so that the complete operation for all
of the
'normal' hard disk partitions are available to it that might be there in a
'normal' DOS-VDM? Such as C:\ D:\ E:\ F:\ G:\ H:\ here? That plus set up
the
complete complex path configuration and so on which is in the 'standard'
AUTOEXEC.BAT that I use here?



You need to look at adding mounting of whatever drives to the end of a *.conf file ie modify dosbox.conf by adding a few mounting lines to the end of the file and saving it as... mike.conf

Here is the end of dosbox.conf modified and saved as redbaron.conf

[autoexec]
# Lines in this section will be run at startup.

mount e e:
e:
cd \redbaron\redbaron
baron
exit


I'm fairly sure that I do not have to explain the above "autoexec.bat" lines except to add that the above could include more drives

mount f f:
mount g g:


The [autoexec] section is also where you would insert your "complete complex path configuration and so on which is in the 'standard' AUTOEXEC.BAT that I use". Note that it may need some modification but you will have to read docs and experiment.

That also applies to the section in the dosbox.conf called [dos] which has these settings

[dos]
# xms -- Enable XMS support.
# ems -- Enable EMS support.
# umb -- Enable UMB support (false,true,max).
# keyboardlayout -- Language code of the keyboard layout (or none).

xms=true
ems=true
umb=true
keyboardlayout=none


It looks to me like this tool is restricted to only one drive and 'path'


Well, that is definitely incorrect :-)

for.
as intended, primarily game playing.

Thanks!



I think it was intended to allow windows users to play their old dos games but developed from there.

I suspect you will need to do a bit of reading and experimenting to see if dosbox can do what you require.
