Hmm... That seems strange. An 80188 is an 8/16 bit hybrid of the 80186. The hardware of this chip makes it non-MSDOS compatible. If you are talking about a MSDOS type laptop, I suggest that you satisfy your curiousity (and mine, for that matter) and open that case and look. This is not to take away from the 80186. It is a good chip with many of the support chips that are external to the 8086 (on the IBM PC and clones) supported on-board the 80186 itself. It has its own interrupt controller, its own DMA, and its own timer. Alot of good stuff on this chip, eh? The reason that it is not IBM (messdos) compatible is because some of the software interrupts that messdos uses are used by the on-board hardware of the 80186. This would make a darn good microcontroller, however. It DOES execute 8086 instructions. Can we say high-level language?? About all I have to say 'bout the matter ...
