I am looking into using a real-time kernel on an embedded 286 system. So far I have discovered the following packages: ZIP C-Executive AMX VRTX QNX <- this provides more than I need I would be interested in hearing from anyone who has had experience with anyone of these packages. A second somewhat related question. I know that MS-DOS and the PC's ROM BIOS are not re-entrant. The packages I have looked at provide drivers to replace the BIOS and make troublesome calls to DOS serial resources. But on the subject of the compiler run-time library I get somewhat conflicting information. Some companies restrict the compilers they support, C-Executive requires Lattice or Whitesmith, because they say the others, specifically Microsoft, can not be used. Others, solve the problem by having each task link in a private copy of the run-time library. Rather wasteful on memory and it may pose problems when I go to ROM or if a task is multi-threaded. What is other people's experience? I'll summarize the information which I receive.

Since they make the chips there should be few problems B-}. We have used it on telephone exchanges with good results.
