Virtualization / Re: Win-OS/2 - Open vbesvga.drv video driver
« on: February 08, 2025, 09:47:27 pm »Hello
Currently my Win-OS2 full screen session (1920x1080) has a "slow-choppy" mouse and you can not move the mouse pointer down from the middle of the screen. (ArcaOS 5.1 BIOS running on a VirtualBox host. )
On the "OS/2, EComStation & ArcaOS Discussion group" facebook page, it was posted something about this new video driver for Windows 3.1:
- https://github.com/PluMGMK/vbesvga.drv?tab=readme-ov-file
It has some instructions on how to install it, but if I follow the procedure and it gives me an error when I load Windows 3.1.QuoteUnsuitable settings for current driver / hardware
Press any key to about booting Windows...
If I only remove from the modified system.ini all the [VBESVGA.DRV] part...Quote[VBESVGA.DRV]...Win-OS2 full screen runs with the newer vbesvga.drv and vddvbe.386. But the screen resolution is smaller (1024 × 768), mouse now works fine and I can go to the bottom part of the screen with the pointer.

Do you think this drivers can be useful for our Win-OS2? Can we benefit in some way from this driver? Any other suggestion on how to make this drivers work at 1920x1080?

I am not certain but I think what is being overlooked is that the WIN/OS2 driver uses I think a special GRADD driver that deals with the WIN/OS2 screen resolution. I think this bypasses the normal DOS video support. This alternative Windows 3.1 video driver looks nice. However you might be out of luck with this driver as I think (based on the file name) this is a VESA driver. And this alternative Windows 3.1 driver then depends on the VESA bios in the DOS session.
But I could be wrng.
