I'm currently having problems getting OS X Snow Leopard installed on my D630.
I have created the USB installation media based upon my Snow Leopard 10.6.0 retail disc. I have to use a USB flash drive instead of the factory install DVD because I do not have a slimline laptop drive that is capable of reading a DL DVD.
I used Transmac to copy from the factory media, format the USB flash drive, and restore the SL image to the USB flash drive, and then copied over the Extra folder provided on the "Creating a USB Pen Drive" wiki entry at http://www.osxlatitude.com/creating-a-usb-pen-with-osx-installation/
I had to use iboot (chameleon, stolen and rebranded) since I do not currently have a working hackintosh or real Mac computer and subsequently the ability to install chameleon to the USB flash drive.
I used iboot (chameleon, stolen and rebranded) to boot the laptop, select the USB installation drive, and successfully boot into the the OS X installation screen, format the laptop harddrive using the Apple disc utility, and then click continue to proceed with the Snow Leopard installation. I get about 2 minutes into the installation and it appears to just lock up. The touchpad no longer responds and is frozen and there is no disc activity. I have let the laptop set for the better of two hours and still no disc activity and visual progression that the installation has succeeded.
I have tried different USB flash drives (8 and 16 GB) with no apparent impact. The installation always hangs about 1 to 2 minutes into it.
Is there a step I missing here? Any pointers or tips that can be provided?
I have also flashed the BIOS to the latest one listed here: http://www.osxlatitude.com/custom-bios-update-with-slic-apple-logo-and-edps-dsdt/
