Actually, it's not that hard to run dos in a v86 box. Find a copy of Al Williams' (useful) book "Dos5: A Developer's Guide." The book isn't much about dos5, and instead focuses on how to write useful stuff that dos fumbles. In particular, it contains code for "PROT," which is a dos extender that runs in protect mode and provides access to the real-mode world through a v86 box. It also contains code to reprogram the PICs to seperate processor traps/execptions/faults from hardware vectored interrupts. A wonderful book, although the code is perhaps a bit hard to read, and PROT is not explained in detail. regards, Mark.
