This was a good book for learning some interesting aspects of conventional memory structure. I used it to build an EMS library for allocating and managing large chunks of memory. Although I was able to figure out how to do what i needed, it still seemed to zip through many of the other aspects of EMS and XMS. I was left wondering why they were doing that, and what this or that really did and why. If you want a good reference for EMS and XMS i think this would do the trick. If you want a good book to learn how it all works, i'd look somewhere else. It covers XMS and EMS 3.0, 3.2, and 4.0. It also has a lot of code included that shows the uses of most of the memory functions including a virtual memory manager that uses XMS, EMS and HD space. This is now just a dust collector since i've switched to using Virtual Memory in Protected Mode, but thats a different story :).
