Part 2 Install Snow Leopard

This section will show you how to get to the Snow Leopard installer and how to run it. Normally it should be as simple as running bootig your PC with the BootCD to load the Chameleon bootloader, but if that fails you have a couple of other options shown here for restoring the retail DVD elsewhere to run later.

Outline of Procedures 1. Booting from the GA-EP45-DS3L BootCD. Note: options 2 & 3 are only required if the BootCD doesn’t work for you: 2. Creating a 8GB bootable USB 10.6 installation memory stick. 3. Adding the Chameleon bootloader to USB memory stick. 4. How to use the Snow Leopard installer.

1 - Boot from the GA-EP45-DS3L BootCD Download the GA-EP45-DS3L BootCD iso from my thread and burn it to CD. http://www.insanelymac.com/forum/index.php?showtopic=180954

1 Turn on your PC and insert the BootCD, pressing F12 to get to

the Boot Menu from BIOS. Important: Wait for the CD-ROM drive light to stop flashing before you press return to select CD-ROM as the boot device. 2 Wait a short while until you see the Chameleon bootloader

device selection screen. 3 At this point eject the BootCD and insert the Snow Leopard

retail DVD. Important: Wait for the CD-ROM drive light to stop flashing before continuing. then press F5 to rescan the devices. 4 You will then see the Mac OS X Install DVD appear at the end of

the device list, press the right arrow key until the tick is above the Mac OS X Install DVD. 5 Press Enter and shortly you will see the Chameleon theme’s boot

logo and the timer spinning..

6 Now this might take a good minute before anything happens,

but soon you’ll be presented with the Snow Leopard installer. Now you can advance to section 4 on page 4.

2 - Restore the Snow Leopard retail DVD As we can’t directly boot our PC’s from the Apple Snow Leopard retail DVD, we have to restore the contents of it elsewhere and then choose to load it from the Chameleon bootloader. Here you have two choices of where you want to put the restored image: • on an 8GB or greater USB memory stick to build a self-contained bootable USB. • on a spare HDD partition (with 8GB of space) to hold the restored image. Once you’ve made your choice, Load up Disk Utility from /Applications/Utilities/ and do either:

Restore to an 8GB or larger USB memory stick • Insert the retail install DVD in to the DVD drive. • Wait for ‘Mac OS X Install DVD’ to appear in the left pane. • Insert your 8GB (min size) USB stick (this can be any format as it will be formatted automatically). • Click the Restore tab in the main window on the right. • Drag ‘Mac OS X Install DVD’ to the Source field. • Drag your USB drive to the Destination field. • Leave ‘Erase destination’ checkbox ticked. • Click the ‘Restore’ button • You’ll be asked to confirm erasure of the partition, click ‘Erase’ • Go and make a cup of coffee • Finished! Note: Because we left the ‘Erase Destination’ checkbox ticked, your USB has now inherited the volume name from the disc image.

Restore to a HDD partition • • • • • • • •

Insert the retail install DVD in to the DVD drive. Wait for ‘Mac OS X Install DVD’ to appear in the left pane. Click the Restore tab in the main window on the right. Drag ‘Mac OS X Install DVD’ to the Source field. Drag a HDD partition to the Destination field. Leave the ‘Erase Destination’ checkbox ticked. Click the ‘Restore’ button You’ll be asked to confirm erasure of the partition, click ‘Erase’ • Go and make a cup of coffee • Finished! Note: Because we left the ‘Erase Destination’ checkbox ticked, your HDD partition has now inherited the volume name from the disc image.

Result Regardless of which method you chose, when the Mac OS X disc image has been restored, your Install USB drive or HDD partition, viewed ‘as list’ in the Finder, will look like this...

3 - Adding the Chameleon bootloader to USB memory stick If you restored the retail DVD to USB then you should still have the USB memory stick plugged in, if you restored to an HDD partition then you now need to insert a USB memory stick and it needs to be formatted to Mac OS Extended file system using a GUID Partition Table (See Part 1 for more info). Also to make the next steps match, it’s wise to rename the USB to ‘Mac OS X Install DVD’. Populate the USB drive Chameleon uses an Extra folder to hold all files required to run OS X. To make it easy, navigate to Support Files/Part2/EXTRA for USB open it and drag the containing folder named Extra to the USB memory stick. Shows Extra folder in Support Files in Part 2

Shows the USB with restored retail DVD

You will also find in Support Files/Part2/Chameleon/ all the files you need to install Chameleon. • • • • •

boot (stage 2 bootfile). boot0 (stage 0 bootfile - boots Chameleon from an active partition). boot0hfs (stage 0 bootfile - boots Chameleon from a non-active partition). boot1h (stage 1 bootfile). fdisk440 (Used to update only the first 440 bytes of the MBR).

Installing these files requires using the Terminal which might seem a bit daunting to start with but it’s straightforward and I recommend you get used to doing this as you might find yourself maybe wanting to upgrade your Chameleon install in the future. • • • • •

• •

Load up Terminal from /Applications/Utilities/ Type diskutil list to identify your drive numbers. Type sudo -s to gain correct privileges. Type cd (then drag the Chameleon folder from the Support Files to the Terminal). Drag file fdisk440 from the Support Files to the Terminal and without pressing return, type -f boot0 -u -y /dev/rdiskX (replacing X with the disk number of your USB drive which you get from the IDENTIFIER column result from using the diskutil list command). Type dd if=boot1h of=/dev/rdiskXsn (replacing X with the disk number of your USB drive and n with the partition number of USB drive we are building, again from the IDENTIFIER column result from using the diskutil list command). Type cp boot (followed by a space) then drag the USB drive from the Finder to the Terminal. Type exit

USB

Congratulations you’re done. At this point you can reboot your PC with the USB drive plugged in press F12 in the BIOS to view the Boot Menu. From that select Hard Disk then from the next menu, select the USB drive to boot from and press Enter and wait a few seconds before being presented with the Chameleon bootloader. All you need to do now is tell Chameleon (with the left/right/enter keys on keyboard) to boot your recently prepared ‘Mac OS X Install DVD’ which will be dependent on which method you chose previously (either the USB you’re booting from, or the HDD partition). Now go to section 4 on page 4.

4 - How to use to the Snow Leopard Installer Click on your preferred language,

If you haven’t already partitioned your target HDD then load up Disk Utility from the Tools Menu at the top of the screen and erase the intended partition as explained in ‘Part 1 - Preparation’.

Select the target drive to install on to. You will want to use the SnowLeopard partition.

Customise your install options. I always deselect everything as I don’t them installed, but it’s up to you what you choose here. Satifsy the Customise window, then click install. This says it will take around 19 minutes on my system.

Note: doradekell posted on my thread that selecting the Printer Drivers caused the installer to fail. Though I have never tested this. http://www.insanelymac.com/forum/index.php?s=&showtopic=180954&view=findpost&p=1251191

Once completed, your system will reboot. If you’re using another OS X system to prepare your 10.6 drive then you can now reboot back in to that. But if you’re building a 10.6 system from scratch with only the BootCD or bootable USB then you will now want to boot with that again in to Chameleon but this time from Chameleon’s boot menu, select your new ‘SnowLeopard’ installation. You will then see Apple’s introduction video and enter the setup procedure.
