I took the PCI Device example from the "FreeBSD Architecture Handbook" as the base, and I added the necessary functionality for BAR and other memory mapping. I created also a user-sapce tool, which connects to the PCI device driver by ioctl() and mmap(), and prints some results. I prepared a .zip-Archive containing these files, and a Makefile for the device driver. Enhanced sources for mypci device driver: <http://www.SimpleCalcX.com/mypci.zip>; Original sources for mypci device dirver: <http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/pci.html>; If you have questions, then please don't hesitate to send a note to this thread on this list. Best regards Rolf
