I am having trouble installing DOS 6.22 under Merge. I get an error VM86 failure.
Further it tells me “ no mono dos image created”
Can anyone shed some light on this? I’m using SCO 5.0.7 and Merge 4.1.1.
Thank you!
I appreciate that you posted this question in the "beginners" category but although it pertains to an ancient system it's not really a beginners question. So I've moved your topic to the SCO category proper where it is much more likely to be seen by SCO experts.
I understand but am having difficulty finding the SCO section. Is there a tutorial on your menu system?
If you pull down the main menu (hamburger icon) you can click on "categories" and it will tell you all the different forums and specialist subject matter available. Hope that helps.
Thank you sir.
Enable the Intel Virtualization Technology, VT-x in the CMOS.
There is no virtualization setting in my cmos unless it’s called something else. Thank you.
What make and model is the motherboard?
There are no labels or identification on this Pentium II motherboard. The label on the bios:
686 AMI Bios 1985
American Megatrends
BU26620
Would a motherboard upgrade fix this? I still need at least one Isa slot. Pentium III?
Hello,
I don't think you need to worry about looking for VT-x settings in your BIOS - this operating system and the application in question pre-date the existence of those features by at least a decade. What might be helpful here is to get the exact full text of the error you are receiving. Does it really just say "VM86 failure", or is there something more descriptive ?
I've not dealt with Merge in a long, long time, but I have at least encountered it in the distant past. From what I recall, it can struggle when trying to do things such as supporting protected mode, or when using applications that use extenders like DOS4GW. So it would also be useful to know at exactly what point in the installation process of MS-DOS this error appears.
Anyway, hope this helps - if you can give us the full text of the error, and a description of precisely where and when it occurs (and also if it always happens at the exact same point, that would be potentially useful to know), we can then try to take things from there.
Unfortunately no other codes or error description was given. Just the two in my initial post. The errors occur after beginning loading Dos 6.22. A file or two get loaded then it pops up.
Hello,
Hmm, OK. I'm not sure what precisely to suggest at the moment, in terms of a fix for the actual problem itself. Out of interest, if you attempt to install a different version of MS-DOS (5.0, or good old-fashioned 3.3, for example), do you get the same error, or does the installer proceed further with those ?
From a quick read through what remains of the documentation for Merge, it looks like 4.1.1 should support up to and including Windows 95, which would certainly allow for installing and running MS-DOS 6.22. So whilst I wouldn't expect this to be an issue, it would still be interesting to see what older versions of MS-DOS do when you try to install them, in case that at least points us in the direction of an issue specific to 6.22 itself.
If it can't install 5.0, or even the lowest-common-denominator version of 3.3, then that more points to an issue with the setup of Merge in some way, since simpler versions of MS-DOS should (in theory at least) be easier for it to support.
Great thought. I actually tried installing dos from Windows 95 which is an option and that totally crashed Merge. At that point I could do nothing.
I too remember SCO Merge from the dim and distant past.
I would be checking..........
Is there enough RAM to run this?
I too would be checking CMOS settings. I seem to remember a setting that shadowed graphics adapter memory into main memory being a problem but whether it was related to Merge I'm not sure.
I too remember issues surrounding the DOS 6.22 version so I would try a different DOS version.
Above is not very helpful I know but this guy made a pile of notes which might be useful:

Thank you, worth a try. I’m trying an older version of Merge as well.
