On: DOS/4GW and Protected Mode (2021)

TSRs were unreliable when they interacted with games and other graphical applications.

Eg, things like a calendar tool trying to pop up a reminder mid-game would often not end well.

My 486 had boot sector protection in the BIOS. It would pop up a Y/N confirmation in text mode during boot sector overwrite.

This froze the windows 95 setup in graphical mode. Although the text prompt appeared for whatever reason the Y/N didn’t work and we could never continue.

So was never able to upgrade that machine.

Yes, I remember that! But at least on my board it could be disabled.
