    Anyone know how to get lion working? XPC just sits there with a cursor in the upper-left corner on my GT680R (after it says welcome to EFI world). Same thing happens in VMware Workstation, but it actually goes to the “duet” screen, but doesn’t detect the virtual HDD or even the USB drive XPC was booted from.

    XPC doesn’t say WELCOME TO EFI WORLD! Pure DUET says it.
    Try disabling serial port or switching it to 0x3e8 port in BIOS.

    I installed your ati drivers for a second time on my iBoot SL 10.6.6 and now it just hangs on the grey screen with the loading circle going around and around… any tips?

    Using the ati radeon 5850 and your kexts
