I beleive that you had downgraded and installed a retail version of XP by erasing the preinstalled version of Vista in your Notebook.
However, all the drivers required for your Notebook may not be available with HP if your Notebook is preinstalled with Windows Vista.
I recommend you to try downloading and installing the drivers for HP Quick Launch Buttons from the link below for the first Unknown device in the Device Manager :
Save the file on to the Desktop or My Documents folder and double click once the download is completed to install the drivers.
For the Ethernet Controller, I recommend you to download the LAN Card Drivers from the link below :
Coming to IEEE 1394 controller, you need to download and install the Chipset Drivers which are available through the link below :
Make sure that you download and save the files in the Notebook and double click them once the download is completed and restart the Notebook after installing each of the drivers provided above.
Hope this helps...

It has to be SFEP (Sony Firmware Extension Parser) device, usually reponsible for special buttons.
Normally you should be able to download it from Sony Website but it's not the first time they screw up - not listing all needed driver downloads.
Anyway, you can SFEP driver from http://www.vaio-link.com/os/vista/64bit/
Note: ZIP file contains both x86 and x64 drivers!
Extract file. Run "Device Manager", right click and install, point to extracted location, should install it within seconds.
For special buttons to actually do something you'll need additional Sony Software, usually called Sony Utilities or similar.
By the way, I use same driver (x64) on my different model.

you would need to get all the drivers for your laptop from the IBM website and install all of them. If you cant find them or need further help please post back and let me know.
