Title: DOS/WIN Issues
Post by: christech on August 18, 2022, 06:14:47 pm
I can't run DOS Windowed, the window opens and the prompt is this: >: and that's all I get. DOS full screen I get the prompt but I can't type anything. Neither windowed or full screen OS2/WIN sessions do anything but lock up the computer. Any suggestions? I already added /int10textgrfxsafe to my config.sys as I found in the ArcaOS website.

This is normal for OS/2 on modern machines. BIOS is not correctly emulated.

viop.sys might help for DOS/Windows full screen. Not sure where to get it.

Waiting for ArcaOS 5.1 UEFI, where both DOS and Windows will be working full screen and in a window.

Depending on how old ArcaOS version, it might be worth installing the updates. Fixes to drivers seemed to help on some systems.

Hi yes it's a new install. I figured it was a BIOS setting and I went back and looked but didn't see any settings. It's a ThinkPad Yoga 20CD.

Hi

You can try the experimental vio-1.0.wpi from this ArcaNoae Ticket. (https://mantis.arcanoae.com/login_page.php?return=view.php%3Fid%3D1193)

Here I wrote something about it.

I finally got the chance to install the patch. It seems now my full-screen DOS works now, before it would open and I couldn’t type anything and also Win-OS2 works for me now Windowed DOS mode still does the same thing with the weird characters. I’d say I made some progress. If it helps I am using an IBM Thinkpad 20CD.

You're lucky it is working in full screen. Lenovo seems to be producing buggier and buggier video BIOSes the newer the machine is.
Once AOS 5.1 is released (almost done), a UEFI install should give you working DOS/WinOS2 sessions.
