I heartily recommend that everyone who programs on a PC look at helppc21.
It's an online reference work for everything associated with a PC -- opcodes
(through the '486), interrupts (dos, bios, mouse), ASCII charts, keycode
charts, hardware descriptions (connectors, chips, bus lines), C functions,
etc.

It works from the command line, or as a TSR.  Written by David Jurgens, it's
a $25 piece of shareware.  You'd spend at *least* that on just one book that
wouldn't have one tenth the information.  This is the first piece of shareware
that I've ever registered -- the first one that I've felt was worth it.

I found it on simtel20:

pd1:<msdos.info>
HELPPC21.ZIP    Extensive PC Programmer's information database

I've also uploaded it to grape.ecs.clarkson.edu, where you can get it
by modem.  Grape is (315)268-6667, 12/2400 baud, 8N1, 24 hours.  You
may need to generate a break to switch to the right baud rate.  It's
stored on grape in:

grape.ecs.clarkson.edu:pub/msdos/prog/helppc21.zip

Same pathname for FTP and modem.
