Have you guys had any issues getting the 48x0 drivers running properly on the Vanilla install? Last week I ordered the Sapphire Radeon HD 4870 1GB
and popped it in the computer this weekend. I booted into my vanilla install and to no surprise I got a flash of blue then a blank screen. I booted into safe mode and installed the drivers and removed the EFI strings and rebooted with -f (dvi2vga adapter in second port, monitor in first port) with the same results.
I figured heck, what do I have to lose, let me try installing it on my iAtkos (rescue) partition. Installed in iAtkos, rebooted, works perfectly without dvi2vga adapter, QE/CI enabled and everything. I think I will wait until 10.5.7 is released before trying to get the drivers working again in the Vanilla install. Call me naieve, but since the new Vanilla kernel will support i7 natively as well as the 4800 series of ATI cards, we shouldn't have to install special drivers.
One thing to note is that the iAtkos kernel at boot time is "custom", whereas I am using Voodoo 9.6.0 "mach_kernel.voodoo" for my Vanilla install... methinks there is a slight difference in how the kext is addressed.
Making some progress getting sound working. The Vanilla AppleHDA.kext was patched using Taruga's AppleHDA Patcher 1.20 with a codec dump produced from Mandriva Linux. I just need to get the HDAEnabler.kext patched with the right pinconfig. Once I have that working I will see what I can do to integrate it with DSDT.amlPower Supply
One thing I noticed this weekend is that the power supply is adequate only for stock stuff and is only good for running apps that don't draw too much power. I booted into Vista and fired up Crysis with the new card. A few seconds after it started rendering the scene in 1280x1024 at high detail, 4xAA, the computer just powered off, no warning whatsoever. I tried it a few more times and it did the same thing. I had a spare 500W PS lying around and figured I'd give that a try. Worked like a charm!
If you plan on doing anything graphic intensive and plan on having more than one HDD in the computer, please upgrade your power supply!
