Tried to install OS/2 Warp 4 in at486 on a lark - the installation claimed to complete but after the "thanks for installing!" screen I got a big red error screen that said the installer couldn't get the installed hard drive letter. I'll see if I can figure out what's going on with it.
If you really want some funky PC hardware, I've got a Commodore A2286AT bridgeboard installed in my Amiga. It's a whole 286 PC on an Amiga Zorro card. I'm not sure how it would fit into everything (it's totally independent from the Amiga, communicating through dual-port RAM and some special BIOS functions, I have the developer manual) but I was able to locate dumps of all the onboard ROMs online. It doesn't boot just putting the BIOS into at.cpp but I didn't expect it to.
