- Although I have not tried this program (at least not that I can recall), if I
- were to make an educated guess, I would bet that you are using a memory
- manager of some sort (e.g., 386 MAX, QEMM386, DOS's EMM386, etc.) These
- programs allow access to extended memory (which required that the machine be
- in protected mode) by running the machine in virtual 8086 mode, in which the
- machine simulates real mode while actually running in protected mode.
- Apparently, PBMPLUS also wants to run in some extended DOS mode to get to your
- extended memory. The two (main) methods of accessing extended memory, DMPI
- and VCPI, are incompatible with one another.
