This could be very useful for those who made a backup of their disk and it was damaged and / or or had a problem with a the cd / dvd drive. This saved me a tone of headache as my Snow Leopard disk was damaged but I had an image backup on a hard drive. You dont have to download the drivers from anywhere, you can extract them and copy/paste them from OS X! Heres a step-by-step guide on making it easy. Part 1 Do not mount the Leopard DMG. If it is mounted, unmount it and then restart (you must restart or it will not work, theres no way to get around it, sorry guys.) Part 2 Open a new Terminal window. If you dont know where to find terminal its in Applications/Utilities. Type in: sudo hdid -nomount [Add a space to the end] and drag the Leopard DMG file from your hard drive to the terminal window. The path will appear, and you can hit enter on the command. This forces the HFS+ partition of the Leopard DMG to not load, allowing the ISO part of the DMG to be booted, which is what we need. If youre not using sudo already, itll ask you for your password, type it in, hit enter, and youll be rewarded with the following: /dev/disk? Apple_partition_scheme /dev/disk?s1 Apple_partition_map /dev/disk?s2 Apple_Driver_ATAPI /dev/disk?s3 Apple_HFS Take note of the ? because youll need to remember it in a little bit. Part 3 We need to make a way for the volume to mount on your Mac, so type in: mkdir /Volumes/drivers Youll recieve no response but this is normal. Part 4 Youre almost there! We now need to force the DMG to load with the ISO volume instead of the HFS+ volume. To do so, simply type: sudo mount -t cd9660 -o nodev,nosuid /dev/disk? /Volumes/drivers Where the "?" is insert the number we mentioned earlier. Without the s. Example from above: /dev/disk? Apple_partition_scheme /dev/disk?s1 Apple_partition_map /dev/disk?s2 Apple_Driver_ATAPI /dev/disk?s3 Apple_HFS You would type: sudo mount -t cd9660 -o nodev,nosuid /dev/disk2 /Volumes/drivers Now you simply have to restart Finder, which is easy to do from terminal: killall Finder Now you just have to copy the drivers onto a USB drive [or burn them to a disc], boot into Windows and install.
