Not so fast. I now have 10.5.7 up and running on my UD3P, installed the 7200 GS, but things still are not right. For one thing I am unable to boot at all via Chameleon, either old or new version (using boot 132 CD to boot now). And now I am limited to using 60 Hz for my refresh rate as all of the other choices are grayed out. One time when I booted nothing worked, there was no background, just blue screen and the dock was gone. Rebooting fixed that, but I'm still not happy with this at all.
Edit: Okay, everyone hold the phone, I'm having a senior moment here. All this time I thought my bios was up-to-date, but it turns out I'm still using the F6 bios! DOH! I always have my logo screen enabled and so the bios version doesn't appear, but when running through the bios settings too many differences showed up in the choices so I decided I'd better check. So let me update the bios and try the update again to 10.5.7, maybe it will go better this time? :roll:
Okay, updated the bios (F9), checked bios settings and did a complete reinstall. Same thing. Even though I specify my resolution in the Uinstaller as 1680x1050, it always comes up as 1440x900. This may have something to do with my refresh rate being at 75 Hz because I think I have to change it to 60 Hz before I can use that resolution. Anyway, changed the refresh rate to 60 Hz and the resolution to 1680x1050 and all it fine, at least until I reboot. Rebooting using Chameleon as the bootloader brings the dreaded YOU NEED TO RESTART message and I have to use the Boot 132 CD to get back in. Using the Boot 132 CD all is fine once I get back into my install. Resolution is where it should be and things seem to work just fine. I may do one more install changing the refresh rate to 60 Hz before I ever install anything and see how that works.
