I'm about to begin teaching myself about 80286 and 80386 assembler with intent of eventually writing my own OS, though in the meantime making some 286 specfic changes to MINIX. What I need is an Assembler book which discusses such things as protected mode and addressing memory beyond 1MB in the case of the 80286 (I assume it's easy (easier?) with '386 ASM). Does anybody have any recommendations? How about good OS books? I have Tanenbaum's book which is excellent.

Does anybody have any recommendations? ... Intel publishes some fairly good stuff themselves: 210498 $22 286 Programming Reference Manual 121960 $16 286 Operating Systems Writer's Guide 231252 free? Introduction to the 386 230985 $25 386 Programming Reference Manual I have all but the last one of these. The second explains in pretty fair detail how Intel expects people to use the 286's rather complicated protection scheme. The third explains the 386 architecture in general, the last I expect explains it in detail. Order any of this from Intel at 800-548-4725. -- John R.
