SZ110 Bought Without Software

I recently purchased a Sony Vaio SZ110 demo system off of ebay. Since it had a password, the seller reformated the hard drive and, with the help of CompUSA, tried to back up some stuff (I'm not sure whether it was from another Sony). Anyway, I received 2 DVDs and a laptop with XP Pro installed. I'm wondering what I should do to recover all the applications and programs.

I've put the disks in the laptop and restarted it, but the system goes through a wizard and tells my that the disks aren't for this model. From one of the disks I've found most of the drivers I need (I still haven't gotten the power utility to show up or the fingerprinting to work). I've also downloaded the stuff from Sony's website, but I still can't get these things to work and I can't get the applications. I've also ordered the recovery disks from Sony, but they'll arrive in a couple of weeks. I'm wondering what I can do to get the computer to a fully functional state with the stuff I have.

Here are some of the questions I have:
1. Does the version of XP that was installed have to be the same as the version used by the factory? (I'm using XP Pro, while they have XP Home, I think.)
2. How can I tell whether the recovery disks the guy sent me are from the correct model. I'm wondering whether they were made using the recovery wizard of this model computer or another one. I get a model error when I use the disks, but this could either be a problem with the motherboard chip or the cd. Are there some files I should look for on the CD to determine the model the disks were made from?
3. What should I do to get the system running with all the applications?

 

there's an extra partition with all the installation tools, check if it's still there.

otherwise search this forum, there's a link to a wek site with all the drivers and application.

 

There's a D drive, but it has a size of 0 bytes. I'd assume it was deleted.

 

where are you living? If not too far I can give you a set recover DVD created from my new SZ-110B
