Oh and another #Book8088 hint from the #RetroHackShack guy:
windows 3 doesn't autodetect mice, you have to go into "control panel" and select the proper mouse...
(and then the book8088 will ask for Windows disk 3, but fortunately will accept D: as a source) 🤗
So the retro hack shack guy says the #book8088 bios blocks floppy drives even if a floppy controller is hooked up.
Can anyone confirm?
