Hello netters,

I'm working on understanding device drivers.

First a little background: This company makes a graphic engine that plugs
into the Q-bus or the VME bus. the device driver is written to support
both BSD (Ultrix, uMIPS), and sysV (m68k). Needless to say, the current
driver is a mass of #ifdef's.

I'm looking for a book, or books, that explain just how one writes a driver.
This will aid me in understanding what I already have.

Thanks in advance.
