Updating from OS X 10.4.11 to 10.5/Leopard or Snow Leopard/10.6

I have a Macbook 1,1 with an Intel Core Duo (1.83 GHz),

2 MB of memory,

SMC Version 1.4f12.

It's currently on Mac OS X 10.4.11 (Tiger), and can supposedly be updated to Leopard or Snow Leopard. I have two Installer disks that came from other computers- an OS X 10.5.7 install DVD for a Macbook Pro (Disc Version 1.0, 2Z691-6435-A), and a Snow Leopard 10.6.8 CPU Drop-In DVD (Version 10.6, 2Z691-6431-A) that came in the hardware bundle.

I have at least 5 free Gigs of free memory, and I ran Disc Utility and did a Repair on my hard drive.

But for no reason I can discern, when I start the computer with either of the DVD's, it gives me an error message; "Cannot Install" or "Requires 10.5", respectively for the 10.5.7 and the 10.6.8 discs.

I also have downloaded Updaters from Softpedia: MacOSX 10.5.6 Combo and a 10.6.8 Updater. Both give me the message: "Couldn't open "MacOSXUpd-------.pkg". This package type requires Mac OS X 10.5."

I don't understand why none of these work. Do I need to get ahold of the first version of Leopard (OSX 10.5) before installing the rest? Can my computer simply not be upgraded, despite what I've read?

HELP. PLEASE. I want to keep this computer, hopefully with all my data intact.

iPod touch, iOS 3.1.3

You can't use either a downloadable updater or a disk which originally shipped with a Mac to upgrade. Click here for the disk you need.

You can not use the DVDs that shipped with a different model. You will need to purchase the retail Snow Leopard DVD. Check the link below for info.

Skip Leopard ($200 on Amazon).

Start by checking if you can run Snow Leopard:

Requirements for OS X 10.6 'Snow Leopard'

http://support.apple.com/kb/SP575

The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:

http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard

and in the UK:

but nobody knows for how long it will be available.

When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:

http://support.apple.com/kb/DL1399

Check via Software Update whether further updates are required.

You should now see the App Store icon in iTunes, and you now need to set up your account:

To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:

You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

Did you read the specifications in the original message? The computer in question meets the CPU and RAM requirements for 10.6.8 but is incapable of running Lion or Mountain Lion.
