Why HN recommends it
Covers low-level PC internals like I/O ports, CPUs, and fixed memory areas; a go-to reference for DOS-era hardware and interrupt tricks, suited to programmers who want to understand the machine beneath the OS.

Probably Peter Norton's Assembly Language Book for the IBMPC. Ray Duncan's Advanced MSDOS was another essential. If you want a bit more esoteric, The Undocumented PC by Frank Van Gilluwe. I could name a few more but I probably shouldn't be admitting that I'm pulling these off my shelves :-)
