Hi,
   I really don't know where to post this message, so if there is a better
place please let me know.

  I want to write a driver for my video card, not for X, for my own home
grown app :-)

  I've just read Chap 5 of the Magic Garden Explained (SysVR4 Internals) so
I have some idea whats expected when writing a device driver.  I've also
read the technical programming doco for my video card.  The big hole in my
plan is PCI.  I don't know how to talk to my video card on the PCI bus :-(

  So I guess my questions are:
	Should I try and find out more about basic driver programming,
specifically freeBSD, and if so where?
	Where can I find out about programming PCI devices?

Thanks for any help,
Anthony
