What is this PC hardware book

[Michael David Crawford <mdc@prgmr.com>]

A while ago I read a post where someone recommended a book about PC 
hardware, and looked it up at Amazon.  It sounded quite good, so I 
thought I would buy it someday, but it's been a long time so I have 
forgotten both the title and author.

The best I can remember is that the author was European, possibly 
German, and that the book was originally written in his native tongue.

Unfortunately, all of my searches for PC hardware just turn up books 
that explain how to build your own box from standard components.

This book explained what all the standard chips in a PC are, and what 
their electrical and programmatic interfaces are.

I'd like to read the book to better understand how to hack on Xen.  From 
the description I read, it could help any Xen developer, quite likely 
even experienced ones.

Thanks,

Mike
