PCI „PRO LIGHTNING V+ “ dual graphic card about dosbox-x HOT 7 OPEN

The second display option, as mentioned on the Wiki is only for adding a monochrome MDA display, not a second VGA display. And even that support is rather limited. A second VGA display is not supported, and would take quite a bit of work to add such support for limited use (I think Win98/ME supports a second VGA display?)

Thanks for the feedback!
I wrote my remaks/questions below.

I think that this has been confirmed, no chance.

A second VGA display is not supported, and would take quite a bit of work to add such support for limited use.
How can this be done? Can I do this? What is the „limited use“?

(I think Win98/ME supports a second VGA display?)
I try a lot of thinks to run the old dos program (dosbox: problems with directories, VirtualBox: I used this very sucessful with an application XP under win7/win10 but I have problems with the RS232 Hardware Interface (also with VMware).
I do not have any driver for WIN98. Will WIN98 be installed under DOSBOX-X?

such "DOS-Program with two Screens" is not a common thing, so would be good if you upload it or share link to archive.org or elsewhere or at least share the name.

"Limited use" was a reference to there being almost no DOS applications that support multi-display, and especially dual-VGA.

My reference to Win98/ME was because DOSBox-X supports running those Windows versions, and if dual VGA support were added, it may be beneficial for it. But apart from that I don't know what else would.

I don't know if you are able to write the support, but I can assure you that it requires a decent amount of knowledge of old PC's, in particular VGA adapters, and to understand the DOSBox-X source code. The fact that your asking the question, makes me suspect you doubt yourself.

I didn't know, I was using such a rarely used configuration (DOS622-VGA-Dual-Screen)!
But unfortunately this application is subject to certain conditions and cannot be published.

About me:
I grew up in the DOS/NC world, have written a few small programs, but wouldn't call myself a programming expert. The DOSBOX-X source code is open? In which language?

from dosbox-x.

OK, but at least share the name of the program (and maybe a screenshot/photo)

DOSbox-X source code is right here, I think mostly C++.

from dosbox-x.

As I wrote before, the program is subject to certain conditions and cannot be published. I read in the introtuction of DOSBox-x: "Our goal is to eventually make DOSBox-X a complete emulation package that covers all pre-2000 DOS and Windows 9x based system scenarios, including peripherals, motherboards, CPUs, and all manner of hardware that was made for PC hardware of that time." So I hope that someone in this community had the same problem and solve it. Unfortunately this is not so. So I have to look in the sources...
