Hi everyone. I too am encountering failure, despite several attempts.
My D630 setup is:
Intel C2D T7500 2.2GHz FSB800
2Go DDR2-667 RAM
160Go SATA HDD 5400rpm
Intel Graphics (965GM) -> X3100?
WXGA+ LCD 1440x900
Audio Sigmatel 9205
Broadcom 10/100/1000BT
Broadcom Wireless
Dell Bluetooth adapter
Unmodded A17 BIOS (i.e. I tried the modded version, but results are worse with it)
Installation attempted with Retail Snow Leopard 10.6.3 DVD.
Initial attempts were with a HDD already set with Win7. From Windows, I reduced the Win7 partition to recover disk space and created a new main partition formatted NTFS.
I made a USB boot key with Nawcom ModUSB + SL 10.6.3. Installation goes through Ok (I believe using legacy_kernel) and everything works at straight reboot of HDD (full video resolution, sound, keyboard, trackpad, wifi + 10/100/1000BT + Bluetooth + dual boot) except two main defects:
1) SL has to be booted with external screen plugged in and video output directed to it (FN F8) otherwise screen goes blank after Apple grey screen with spinning wheel. With external screen plugged in, screen reverts back to built-in LCD to provide initial Welcome Video/Normal boot completion (this is not reached with modded BIOS).
2) can only update to SL 10.6.7 (without single issue), but SL 10.6.8 causes unrecoverable boot failure.
This is the closest I can get to successful installation! If EDP 1.9.2 kexts are then installed, I will just get blank screen on built-in LCD at end of boot, no matter what.
I then decided to copy the bootpack to the USB boot key, thereby replacing ModUSB's Extra folder. The result was a system only partially installed:
1) built-in keyboard was not recognised, I had to use external USB keyboard.
2) after installation of EDP 1.9.2 and appropriate kexts + Chameleon installation, I only obtain blank screen at reboot! If I boot with external screen plugged in, built-in LCD remains black but external screen is usable (albeit empty because acting as 2nd screen).
3) only if I reboot off USB key and then select newly installed SL partition do I obtain full reboot on built-in LCD, but I cannot get full screen resolution and other stuff.
4) no installation possible on MBR partitions, I had to delete everything and opt for GUID partitions.
I then decided to follow the Wiki's recommendation and, using previous partial installation, went the MyHack way. I deleted my USB boot key and restarted everything with MyHack 3.1 + Retail SL 10.6.3 DVD. It took a while, but new USB boot key was created and I replaced the /Extra folder by that of the Bootpack.
Installation is then a complete failure. On pressing F12 to select USB key to boot from, I do get the Chameleon screen showing "My hack OS Install disk" from which system appears to boot. After some lenghty period of time, screen for to grey Apple logo with spinning wheel, but after some additional period of time, screen just goes blank!
I've tried to use various options/flags to fix the issue (-x/-v/-f/PCIRoot=1/GraphicsEnabler=No), but no success.
Could anyone provide a detailed step-by-step installation method for that lappy? How did those who succeeded manage to get SL 10.6.8 installed?
Thanks in advance for your advises.
