- 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.
