It appears that some visitors to my site are looking for some old info. I'm adding this post mainly so that it will be in the archive and searches for this information will work.
The PCI device driver tutorial (for Mac OS X/Darwin) lives here. Although there is probably an updated version of this information somewhere on Apple's developer site. The tutorial is a series of email messages from Apple employee Godfrey van der Linden posted to the darwin-development list.
WebObjects WWDC 2000 slides and sample code are here. It's still worth a read even though many of the examples are in Objective C.
