Re: DRI on FreeBSD with a PCIe X800

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

So something occurred to me last night...  I've seen these same symptoms
before when trying to get DRI working on FreeBSD a long time ago... On
another machine, if I accidentally had the AGPSize set to a value higher
than was set in the BIOS, I saw the exact same problem in FreeBSD (but
not in Linux, which didn't have any problem with that particular
situation).  I don't have any config options set for GARTSize, but could
something similar be happening now?
