Please set your mailer to wrap long lines at 70 columns or so, so it is readable. Your text goes way off my screen, so I can only respond to what I can read, and make assumptions from the rest. It'd be nice if you'd trim excessive list headers/footers and other non-essentials in quoted replies also. ;o) >So ForcePCIMode yeilds the same results as the driver the mharris pointed to in the aforementioned link. And this is the case w/o ForcePCIMode and w/o mharris's tweaked driver. ForcePCIMode, and the AGP autodetection logic in 4.3.0, and also in current 4.4.0 are totally broken crap. I have written a Radeon driver specific quick hack to for once and for all *properly* autodetect AGP/PCI hardware by walking the PCI capabilities list in PCI config space. The patch is in my 4.3.0 src.rpm in fedora development. Anyone using stock 4.3.0 or XFree86 CVS, or any Red Hat builds prior to my patch (check the spec file changelog for what version/date it went in on), will have a possibility of misdetection. In some cases, PCI devices will be treated as AGP, in other cases AGP devices will be treated like PCI. While the latter should work, due to PCI support not being 100% stable, it can result in AGP Radeon hardware being totally unuseable. >Also, noticed the 'ForcePCIMode' bug in XFree's buggzilla and the BusType is the way to go - 'cept that must be a XFree 4.4 thing, because the log file just mentions that it is ignoring it as unknown.. That override might go away once I submit my patch to fix AGP autodetection. >I was hoping to tweak/tune/config this without having to recompile anything....that doesn't look promising... Use rawhide XFree86 and it should "just work". If not, submit a bug report and I'll investigate, but so far all known problem cases have went away on x86, AMD64, ppc, etc.. Hope this helps. -- Mike A.
