I was able to install IBM OS/2 Warp 4.0 and 4.52 in 86box. The boot disks found online for 4.52 are corrupt. Also, you cannot install 4.52 on a blank hard disk. You have to install it on top of 4.0, even though it makes you format the drive during install. I think it was IBM’s version of licensing enforcement. You just install 4.0 with the boot floppies that come with 4.0. Then you insert the 4.52 CD and run cdinst.cmd on the CD and make your own virtual boot floppies for 4.52. Then you use those new boot floppies to install 4.52 over 4.0. The 86box configuration is below. You have to change the video card to install 4.52 and use the Selective Install program inside OS/2 to install the video and sound drivers after you install 4.52.
