If you can tell me how to get the useful information directly from OFW, I'll be happy to type them in manually, though. If possible, I can query necessary information from ddb as well. > - - dmesg output The info from dmesg you need I can tell you as well (see also below). Do you really need all of dmesg? It would require me to copy it manually too.. I enabled GENFB_DEBUG and got the following output just before the top part of the screen went black: genfb0 at pci0 dev 2 function 0membase: 1ff80000000 fbpa: 1ff80800000 : Texas Instruments TVP4020 Permedia 2 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>OFpnode</key> <integer>-267800264</integer> <key>address</key> <integer>0x800000</integer> <key>cmap_callback</key> <integer>0x18a9850</integer> <key>depth</key> <integer>0x8</integer> <key>height</key> <integer>0x400</integer> <key>instance_handle</key> <integer>0xfff69ce8</integer> <key>is_console</key> <true/> <key>linebytes</key> <integer>0x500</integer> <key>width</key> <integer>0x500</integer> </dict> </plist> It has become dark outside now and there's less light falling into my screen. This made me notice that the black section at the top of my screen with the "white dots" isn't completely black. It's a very very dark grey and when I look closely I can see in black what looks like dmesg lines. It's too small to read, but it's repeated four times across the top of the screen. I also see four completely white rectangles which seem to be copies of the cursor. > Then, TechSource sold many different cards as 'Raptor' - are you sure > yours is a Raptor GFX 8P or Sun PGX32? Nope, I'm not sure. Can you get anything useful out of the genfb line above?
