Well, this book was recommended to me by a person who I inherited a design
from, that I had to convert to use FibreChannel using ISP2100 chips from
QLogic; these chips had PCI interface to connect them to memory etc. He
praised that book over others (and I did order another book too) and I found
he was right. Unlike other this one was very practical.

I designed (first time in my life) PCI bus, that worked from the start.
Despite all the crap I put into my first CPLD edition of the PCI arbiter
:-))))
