Actually, its most safe to default to AGP mode 1x. If we aren't switching modes correctly there is a bug in that agp driver, and I'd like to know about it. Try to enable 4X in BIOS of SiS Athlon chipset, startup X in default mode, SPLAT. This is a widely known problem and you aren't going to get all of the chipsets right in particular the AMD76x ones. I'd suggest rethinking the "use 1X by default" logic, it's wrong in half of the cases. Unforunately there is no real way to test if anything above AGP mode 1X works correctly. Defaulting to AGP mode 1X is the best option, since AGP mode 2X might cause the machine to lockup upon initiating a DMA request. Certain card/motherboard combinations just don't work above 1X. I totally disagree, you're locking up now on half the chipsets if the user enables anything other than 1X mode in his BIOS. The reason the machine locks up on >1X mode is for the same damn reasons, the driver isn't programming the chip correctly or we lack the workaround which in a manner of speaking is the same problem. _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
