Backing up Tiger for Install of Leopard

Ok, I've got Leopard and it should be arriving monday. My plan is this:
I have a new Seagate Freeagent 500gig external USB hard drive. I want to save a backup of Tiger (Bootable if possible) so that if anything goes wrong with the install I don't have to worry too much. However I also want to backup my Windows XP partition as well.
Once both drives are backed up and Leopard's installed fine, is it possible to erase the external drive safely?
After installation I plan on partitioning the external drive, the majority of the space as backup for Time Machine and the rest for storage of films I've edited and don't need clogging up my MBP hard drive.
Does this sound like a viable plan?
Any suggestions welcome.
Thanks
Chris

This sounds very similar to what I intend doing--just waiting until I get the various bits in place first, so I'd say its a good plan But then I'm biased since its similar to my own...! (I've done quite a bit of reading first and have been 'round the loop on updates, etc.)
Personally, I have one extra wrinkle to how I do this. I separate my hard drive space into "System", "Work" and "Archived" partitions to make backups and installs, etc., easier. No "user" data in "System", so overwriting the system doesn't affect my data. There's no need to backup "Achived" (its already archived...). Soft links or aliases point from Work to the Archived stuff where needed. It means a bit of work initially, but helps with the on-going maintenance once its in place.
I've read elsewhere that you don't have to start Time Machine immediately.

Procedure for installing OS (Leopard) in a new hard drive unit.

I am running a Powerbook about two years old under the latest version of Tiger, and I want to do some renovation and increase the performance of it before installing Leopard, such as buying an additional 1gb of ram (resulting in the max of 2gb of ram), and also change my hard drive from a 100gb 5400 rpm, to a new seagate 100gb 7200 rpm.
My question come to this: if I have my Leopard DVD, and I have finished installing the hardware on my Powerbook. What comes next to install the DVD: (just as a note, I wish to have a clean install of my OS)
- I will probably install the ram under Tiger, and make sure that it is recognized, etc.., and then move forward to the hard drive change.
- should I insert the DVD (under Tiger), shut down my laptop, perform the change of hard drive and then press the "Power button" followed by the boot command key, and it must be immediately recognized?
- or, should I proceed to change the hard drive and after it has been physically installed, when I turn "ON" my laptop, I should be able to insert the DVD and press the boot command key?
- Which is the best procedure for what I am trying to achieve? are both of these possible? is there any difference or preference whatsoever? I will appreciate any feedback or warning on any preparation that should be made to the hard drive when it is new. Should it be pre-formatted? or will it work straight out of the box in order to initiate the installation process.
first time doing this type of hardware changes, and I'll appreciate any recommendations or thoughts on this.
for reference, I am planing on buying these products:
*1.0GB PC2700 DDR SODIMM 200 Pin Memory Module 128x64 CL 2.5
*100GB 2.5" Seagate Momentus 7200.1 7200RPM ATA Notebook drive
Initially I am thinking on buying these over at OWC.
thanks,

orlandold:
Your plan to install the RAM and test it with Tiger is fine, although not necessary. You can install it at the same time you install your HDD. Either way will be fine.
Once your new HDD is installed, follow these directions:
(Note: they are written for Tiger and earlier, but should work fine)
Formatting, Partitioning Zeroing a Hard Disk Drive
Warning! This procedure will destroy all data on your Hard Disk Drive. Be sure you have an up-to-date, tested backup of at least your Users folder and any third party applications you do not want to re-install before attempting this procedure.
Boot from the install CD holding down the "C" key.
Select language
Go to the Utilities menu (Tiger & later) Installer menu (Panther & earlier) and launch Disk Utility.
Select your HDD (manufacturer ID) in left side bar.
Select Partition tab in main panel. (You are about to create a single partition volume.)
Select number of partition in pull-down menu above Volume diagram.
(Note 1: One partition is normally preferable for an internal HDD.)
Type in name in Name field (usually Macintosh HD)
Select Volume Format as Mac OS Extended (Journaled)
Click Partition button at bottom of panel.
Select Erase tab
Select the sub-volume (indented) under Manufacturer ID (usually Macintosh HD).
Check to be sure your Volume Name and Volume Format are correct.
Optional: Select on Security Options button (Tiger & later) Options button (Panther & earlier).
Select Zero all data. (This process will map out bad blocks on your HDD. However, it could take several hours. If you want a quicker method, don't go to Security Options and just click the Erase button.)
Click OK.
Click Erase button
Quit Disk Utility.
Installation Process
Open Installer and begin installation.
Choose to Customize and deselect Foreign Language Translations and Additional Printer drivers.
Check box to install X11 (Tiger) BSD Subsystems (Panther & earlier).
Proceed with installation.
After installation computer will restart for setup.
After setup, reboot computer.
Go to Applications > Utilities > Disk Utility.
Select your HDD (manufacturer ID) in left side bar.
Select First Aid in main panel.
Click Repair Disk Permissions.
Connect to Internet.
Download and install Mac OS X 10.4.11 Combo update (PPC).
Computer will restart after updates.

IPhoto Do Not Load after Downgrading Back to Tiger

Hi. I bought and installed Leopard on my computer, but mainly because of some stability and compatibility issues, I decided to downgrade back to Tiger for now. I used my MacBook Pro installation disk to reinstall Tiger, leaving all the system files intact, and so far, Tiger has been running with no problems. I did notice though that some applications, such as iPhoto and some other iLife '08 applications, do not load, but most of the third party applications so far, such as Parallels, were fixed by reinstalling it onto my HD.
On the other hand, I have tried to reinstall the iLife programs a couple of times, but my iPhoto application keeps on failing to open. Does anyone know anyway I can fix this program, or any suggestions/feedback on this matter at all?
Thanks

First step is to use Disk Utility to Repair Permissions before and after any update, install, or upgrade, reboot after each Permissions Repair.
Might Verify the HD before fixing permissions also.

Will Tiger be freeware once Leopard is launched?

I wonder if Apple will release Tiger for free, when Leopard is launched (next month??)?

Hi Tom Gewecke,
As I remember it, System 7 was the first System software that you had to buy. All the previous ones were free. Just a small bit of historical trivia

Install left problems HOW CAN I GET BACK TO TIGER FROM LEOPARD?

so i upgraded from tiger to leopard, then i had a few problems, i.e. itunes would quit everytime i tried to delete a podcast, or editing multiple song info would make it crash. My ms word continously crashes as well as ichat.
So since i really need this maching working for school, can anyone tell me how to get back to tiger?
i tried an archive install and that did not work, i also tried creating a user acount and i know the problem lies within my primary user account, not other newly created accounts, i also tried removing cache and some plists so it would rebuild but still same problem.
So, CAN ANYONE TELL ME HOW TO GET BACK TO TIGER WITHOUT LOSING ANY OF MY DATA? PLEASE?
THANKS

You can do an Archive & Install back to Tiger.

Best practice for preparation of install of Leopard from Tiger

Hi all, I am about to upgrade my iMac with an Archive and Install of Leopard 10.5 from Tiger 10.4.11.
I've done this dozens of times on other machines, but I never really thought about the best way to prepare for an install, I have already backed up this machine using Carbon Copy Cloner, is there anything else I should do before hitting the button?

Run the Disk Utility Repair function (or at least Verify), and also the Repair Permissions, which takes many minutes. This will help assure Integrity of your directory before you begin.
I am not sure why you are choosing to Archive and Install. An Upgrade install will be offered, and is thought to be just as effective, and can be a little more convenient in that your non-Apple Applications are not moved into the "Previous System" folder.
The absolute BEST practice would be (after you make TWO backups) to erase your Hard Drive with the Write Zeroes/Zero All Data Option. This will take many hours, but will force the drive to substitute spares blocks for any found to be defective after the Zeroing. But I must say that in the absence of error messages indicating disk trouble developing, this is incredible overkill. You asked, so I am answering the question as you asked it.
Message was composed over a long period of time due to multiple interruptions.

Im trying to instal snow leopard on my macbook. its running tiger 10.4.11 and it meets all the requirements but it ask me for a restart to begin instalation progres, i restar it and it doesn't happen anything

im trying to instal snow leopard on my macbook. its running tiger 10.4.11 and it meets all the requirements but it ask me for a restart to begin instalation progres, i restar it and it doesn't happen anything. anyone can help me?

I assume the restart was prompted during the installation process?
First of all, that restart will take several minutes while files are moved into place and should not be interrupted.
If it fails, or you have interrupted the process, you'll need to boot from the installer (hold down the C key on startup) and use Disk Utility to erase the drive prior to continuing the installation.
That will wipe all data on the drive, though, so if you didn't make a backup before beginning the upgrade, you'll need to get your data off safely before proceeding. That may likely require the use of another Mac to access yours in Target Disc Mode.

Uninstall snow leopard and go back to tiger 10.4.11

On apparently bad advice I installed snow leopard. Now my Nikon software does not work. I want to go back to 10.4.11. Do I have to erase the disk? I put the original 10.4.3 disk in, but the computer wanted to start it using rosetta.

Yes, you will need to erase the drive and install Tiger from scratch. You may want to make a backup of your current drive just in case. I suggest cloning it to an external drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external drive.
Source means the internal startup drive.
Since I assume your iMac is an Intel model you will have to use the original installer discs that came with the computer. You cannot use a retail copy of Tiger. To start:
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Extended Hard Drive Preparation
1. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
After formatting has completed quit DU and return to the installer. Complete your installation.

I GIVE UP! Is it possible to uninstall Leopard and go back to Tiger?

I am ready to give up for now. Is it possible to uninstall and go back to Tiger?

If you were wise you would consider other options just besides getting rid of Leopard and throwing it away. First, you could wait until Apple releases OS 10.5.1, then install and update to it. This might help take care of some problems. You could dual boot OS 10.4.10 and 10.5 as long as you have the OS 10.4 full install Disk and the OS 10.5 full install disk. I personally will wait until at least Christmas time before I install Leopard. New OS's are always full of bugs. On the Microsoft side, I've read where Windows Vista is still having major problems and is taking a long time to become widely used. These problems take time to fix. When Windows XP came out nobody would upgrade to it because of all it's bugs, now Windows XP is considered the standard on PCs. Mac OS 10.4 was also full of bugs at first, but now we talk about how rock solid it is. Simply give Apple time to fix these problems.

From Tiger to Leopard. And back to Tiger...

hi =)
i was running tiger 10.4.10.
i upgraded to leopard quite smoothly.
then i installed the 10.5.1 update.
all went downhill from there on. i always verify/repair permissions + check HD before and after each installation, in addition to running the extended hardware test.
this evening, i finally gave up on leopard, erased my HD and reinstalled everything from the DVDs that came with my macbook (bringing me back to 10.4.8), as leopard could not install due to the macbook crashing all the time during installation (thank you 10.5.1).
i then ran my bootable clone external harddrive using superduper (thank you for backups!) to erase the HD and clone itself on the HD.
so basically, i am back to where i was before the leopard upgrade, i.e. in 10.40.
no data loss of any kind and all applications have updated smoothly, etc.
question:
considering the hassle experienced with 10.5.1 under leopard, and now that everything is running fine, should i tempt faith with the 10.4.11 update? or wait for the next one?
i might reinstall leopard eventually, as that upgrade went smoothly. it was only the 10.5.1 that created havoc.
thank you for your thoughts =)
dominique

hi barry
and thank you for the message.
i am using a USB modem to connect to the net when in the office, as access to some websites (myspace notably) is blocked on our company network.
these USB modems and their related software proposed here in swizerland are still only compatible up to 10.4.10.
so i might hold off on the 10.4.11 upgrade or going back to leopard until all non-apple applications i use (USB modem + superduper mainly) are compatible.
for superduper, i was manually updating all important files and folders on the lacie eyternal disk, so as not to lose its bootable capacity, which would have been lost by running superduer with leopard.
worked well, but a little time consuming =)
patience is the game sometimes.

Power Mac G5 Dual 2.3 freezing from Archive Install of Leopard from Tiger

Just archived and installed Leopard from Tiger 10.4.10 and on all our Macs, but our only PPC system is having serious issues. The system boots up fine, faster than before, however the Finder and desktop freeze when booting into any of the two user accounts. Applications run from the dock, but the Menu Bar isn't loading fully (airport, bluetooth, clock, etc don't load). I have run Activity Monitor from the Dock and systemuiserver and finder both freeze. I have reset the PRAM and NVRAM, and in the one instance I was able to get into the files I deleted the systemuiserver and powermanagement plist's.
Upon many hours of research with Apple and at home, nothing seems to be the solution. If I can't resolve this I may have to install a copy of Tiger (or Leopard) on an external HDD, boot and attempt data recovery from the main HDD (if nothing is locked) as a lot of Quicken 2007 files are needed and perform a clean install. If any one is able to give any help I'd greatly appreciate it. Thanks!
Also, the Power Mac G5 is Dual 2.3 late 2005 model (specs: http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html ), with 1 GB RAM, ViewSonic VGA monitor, NVIDIA GeForce 7800 GT with 256MB of GDDR3 SDRAM, Airport + Bluetooth, and wired keyboard and mouse. Thanks again!

So, would you recommend to people having this same system (as I do) to wait for installing Leopard or maybe to take some precautions?
I would either:
A) Wait until 10.5.1 has been released (which may address such issues)
B) Take serious precautions. Back everything you need onto a separate HD and perform a clean install (which formats your HD), then move everything copied back into the system to ensure no data is lost and nothing corruptible is carried over into Leopard.
Performing the clean install seemed to take care of any conflicts and issues, but means more time will be spent manually backing up and reloading all personal data.
Hope this helps and good luck.

====================================
I have read about the new features in Leopard and would like to have them. At the same time I have read about dissatisfied user reviews about Leopard, mainly from non-Intel based Mac users. So I started this topic hoping to get an answer whether it is worthwhile for me to upgrade to Leopard as soon as possible, or wait til Apple releases more patches for Leopard to iron out the problems?

Sorry about the complexity, but my purpose for the work I did, and the way I did it was to safely upgrade a nicely running Tiger installation to Leopard, with minimum downtime incase things went badly.
The MBP internal drive that Apple uses is only 5400RPM and can't transfer data to boot the operating system or applications as fast as almost any drive in a PowerMac. Even with the ram maxed out, I was not getting all the performance from Tiger that a comparable PowerMac with the same CPU and video could get. Almost all modern PC's and Macs use 7200RPM (or faster) drives which can access and transfer data about 25% faster.
I decided to install Leopard to an external FW800 drive. I used an external drive because I didn't want damage my perfectly good running Tiger installation on the Laptop. I used FW800 because it is presently the fasted port on the Mac that supports booting. eSATA cards are available, but none of them guarantee booting.
I had already tested running applications from both drives by copying the WinXP hard drive file for Parallels and timing the launch from both drives. The external drive was at least 25% faster to boot Windows, and launch other large programs like Photoshop and GoLive.
So, I bought a 500GB newerTechnology miniStack V3 FW800/USB2/eSATA drive. This covers all the bases, Mac and PC, and will be useful for many purposes over the coming years. Who knows, Apple may support booting from eSATA on my next Mac and this drive can run even faster.
I installed Leopard to the new drive a couple of times. First, a clean install with none of my files transferred. This worked perfectly as far as all the hardware compatibility, and applications including TM worked perfectly.
Then I installed Leopard again and imported my applications and settings. This led to a couple of problems that were fixed with a couple of software updates and I fine tuned TM to a degree.
During the next 2 or 3 weeks, I only had to boot back to Tiger on the internal drive 3 times (out of the office).
Once I had a seemingly nice running installation of Leopard with all the updates and Time Machine tested as working well, I decided to clone my old Tiger installation onto an older slower USB 2 drive by using SuperDuper. I booted off of the clone to make sure it was good to go and then set that drive off to the side. It will get used for other projects in a few months, so no money wasted.
I installed Leopard onto the internal drive and imported my settings and files from the external drive. I made sure the system runs and the applications and files I need are available while out of the office.
What I ended up with, is a significantly faster Mac when working in the office with a second monitor helping the workflow, and a fresh, tested Leopard installation running Parallels and WinXP while on the road. When I bring the laptop back in from a field visit I boot from the internal drive and run TM if there has been many changes, then reboot back onto the external drive to do my normal work. I only leave the office with this MBP a day or so a week, and do almost all of my production work at the office on the faster drive.
Win/Win - if you need to spend money for an external drive, get the most out of it you can. In this case, I was also able to ensure that if my MBP is stolen, or hacked while in the field, my personal and financial records would not be on the Laptop.
OK, fingers tired...

Installing Snow Leopard on a MacBook that is currently running Tiger

Is it possible to install Snow Leopard on my MacBook that is currently running Tiger? I have heard rumors that Leopard must be installed before Snow Leopard will work. I bought a white MacBook about three and a half years ago with Tiger installed.

1. The Snow Leopard installer itself runs the equivalent of Disk Utility's verify disk step on the volume selected for the install, so while this remains a good idea when upgrading to Leopard or other previous OS versions, doing it as a separate pre-install step is not necessary or likely to improve anything when upgrading to Snow Leopard.
In this respect the installer is quite finicky: if the volume doesn't pass verification, it will refuse to begin the install.
2. Aside from that, the installer is only finicky about two other things regarding format: (a) the drive must be formatted with the GPT (GUID Partition Table) partition scheme (the scheme the drives of all Intel Macs ship with) & (b) the table must conform to the standard GPT format. If the drive doesn't meet these criteria, the installer marks any volumes on it as not suitable for the install & users can't select them.
3. Some users seem unaware of just how different the Snow Leopard installer is from the earlier ones. When Apple talks about streamlining it in the product's blurb, it refers to much more than just eliminating the old Archive & Install and Erase & Install options, notably:
• Unlike the old Upgrade option, SL's version completely replaces the existing OS component files with the ones from the installer's 'payload.' (The old Upgrade option just replaced or patched components that had been changed for that OS version.) This is why the single provided option is equally suitable for a volume that contains an existing OS or an empty one. (It's also why upgrading from Leopard or Tiger works essentially the same way.)
• The new installer doesn't create a "Previous Systems" folder like the old Archive & Install did. There is no reason for this largely redundant folder anymore, since the new installer selectively leaves in place user-added items from the old system folders that they previously had to move back into those folders manually if they wanted to restore their functionality. However, if the "Previous Systems" folder exists because a user did an A&I with an older OS installer, the new one leaves it in place. But since the new OS ignores it, just as previous ones did, this has no effect on OS operation.
• If -- but only if -- users start the install process by launching the "Install Mac OS X" pre-install application while running from an installed OS, that app will use the installed OS's network settings to 'phone home' to Apple's database of software known to be incompatible with Snow Leopard & use that info to decide what if anything to move to a root level "Incompatible Software" folder during the install. The DVD has its own short list, but since that list was created before the DVD was made, it is now out-of-date & incomplete. Thus, it is always a good idea to start the install this way when possible, just as Apple recommends.
• Other minor refinements that only work if there is an existing OS include automatically deciding if Rosetta or Quicktime Player 7 should be installed, automatic language selection for the install process, & enabling the 'install drivers only for local & nearby printers' option. Each of these depends in some way on what's already installed.
4. All these refinements do not make the new installer 100% reliable but they eliminate the most common problems users had with the older ones, especially if they follow Apple's instructions & *do not* erase the drive beforehand. Just as the Installation Guide included on the disc (also available online here) says in the "Advice about installing" section, erasing the drive should be reserved for the rare times when the normal method fails.

From Leopard back to Tiger

Odd question to ask I know but have experienced some problems since upgrading to Leopard, one being that my Superdrive no longer burns DVD's!! This appears to be an ongoing thing judging by some threads I've seen and I can't really afford to be going out and buying an external DVD burner! How easy should it be to go back to Tiger?
Thanks for any help

Yes, you can do the same as you did previously, with one exception. When you were installing Leopard you were going forward with a newer OS X version.
However, your Mac will block you from installing backwards unless you click the "Options" button at the bottom of the Destination selection screen early in the install process. You will then need to choose the type of install you will be doing, or you will need to choose to erase everything on the hard drive - Leopard and all else. Otherwise, your Mac will block you from accidentally going backwards with OS X by mistakenly using an older install disc, the result of which would be to destroy a more current OS X system.
If you have files you want/need to save from the Leopard hard drive, you should burn them to disc, copy them onto another Mac or onto an external hard drive, or copy to some other backup. If none of those are possible and you have enough empty space on your internal hard drive to keep everything on it now AND also install Tiger, you can use your Tiger install disc to "archive and install" a new OS X Tiger along side your current OS X Leopard folder. Afterwards, you would be able to move your files from the archived Leopard folder to the new Tiger folder.
If you proceed without noticing the "Options" button, and see the "Customize" button at the bottom of the "Easy Install" screen, you have passed the screen where the "Options" button was, and you need to back up to the previous page to access it. Once you have made an "Options" selection, you will have removed the OS X block and you will be able to proceed with the install of Tiger.
If you choose to Archive and Install - once you have Tiger installed and setup the way you need and have moved all your files over to the fresh Tiger system, you can then throw into the trash the archived folder containing your unwanted Leopard system. Once you then empty your trash, Leopard will be gone, and you will have back the hard drive space.

First, install OS X, then install your third-party software.
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal
startup drive.
C. Important: Please read before installing:
1. If you have a FireWire hard drive connected, disconnect it before installing the
      update unless you will boot from this drive and install the update on it.
      Reconnect it and turn it back on after installation is complete and you've
      restarted.
2. You may experience unexpected results if you have installed third-party system
       software modifications, or if you have modified the operating system through
       other means. (This does not apply to normal application software installation.)
3. The installation process should not be interrupted. If a power outage or other
      interruption occurs during installation, use the standalone installer (see below)
      from Apple Downloads to update. While the installation is in progress do not use
      the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
      1. Insert OS X Installer Disc into the optical drive.
      2. Restart the computer.
      3. Immediately after the chime press and hold down the "C" key.
      4. Release the key when the spinning gear below the dark gray Apple
          logo appears.
      5. Wait for installer to finish loading.
      6. Follow instructions.
After installing Snow Leopard you should update it by downloading and installing Mac OS X 10.6.8 Update Combo v1.1.
