Great snapshot for the turn of millenium. Thanks for posting and triggering the trip down memory lane.
Especially nostalgic for me personally as I was in the midst of coding early Windows and OS/2 kernel mode device drivers for scientific instruments, not to mention having written my own multi-tasking RTOS for the 186, at the peak of my career at that time. I remember most of these books, and had dog-eared copies of a few of them (particularly Baker's Device Driver book.) The only other book on Operating Systems that I see missing from this list, and probably would have included at the time, would be Donovan's.
