Successful Install Notes P8P67/Radeon 5850/Displayport

[drvelocity]

Hello,
Have you tried running R5850 in 64-bit mode? I have the same MSI card as you but could not get 64-bit to boot. 32-bit with ATY_init Uakari and ATI experimental bootloader works fine but no go for 64-bit

See here for more info on 64-bit ATI support:

I can get into 64-bit mode, and everything works, but the graphics are extremely sluggish, even just clicking a menu item gets about 1 FPS on the fadeout. So probably something to do with the correct drivers not kicking in under 64-bit mode?

How did you get it to boot?

creating 1002_6899.rom into /Extra? Modify com.apple.Boot.plist?

Which AtiConfig did you try? Perhaps using different framebuffer helps?

I didn't have to do anything other than select ATI Experimental Boot, and 64-bit Apple Boot Screen in the Multibeast options. No special AtiConfig either.

I have almost the same configuration (i5 2500k p8p67-m and HD 4890).

SL retail dvd will arrive tomorrow.

The BIOS is updated.

I will follow your sames steps.

Could you tell me how you've set the bios?

Thanks in advance

Thanks so much!

Followed you instructions for this board and it worked!

If you disable the SpeedStepping in bios the installer will take, otherwise it won't allow it.

Will post again if anything notable comes up!
