The video cards usually have nothing to do with the kernel itself. Their drivers are in the X Window system. Probably the easiest fix is to just install an older version (3.x probably) of XFree86 on your machine. >So I guess that makes my question fairly simple then; I know that driver >code is written in C (which I am learning currently) but thats about all Well, you usually need a bit more expertise than "learning currently" to write drivers. >I know.

Searching for "device driver" turns up a lot of books on Amazon. For the system-specific details look in the online FreeBSD Device Driver Writer's guide (part of the Handbook if I remember correctly). Anyway, for the graphical cards it's not what you need. The graphical drivers are running in user space as a part of X server. Writing them is a completely different story and I don't think there are any manuals. Just look at the code of the other drivers and do the same. -SB _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
