Also worth noting is Abrash's Black Book is pretty specialized for the x86 PCs of the 90s. It's not really all that applicable to game programming today, unless you're deliberately doing retro development for 486/pentium class machines w/VGA.
It's kind of mind boggling how things have changed from doing your own bit blitting to having Unreal Engine doing all the hard work and you just coding up the game logic.
