jkOnTheRun posted an article on how to downgrade the Windows Vista version of the HP 2133 Mini-Note to Windows XP, I’ve linked the instructions below from bsumpter over at notebookreview.com’s forum since Heyman just asked for it, hope it helps. Full thread on the post is linked here.
1) Plug in USB DVD / CD drive, insert WinXP disk.
2) Boot computer, hitting F9 at bootup to choose boot volume.
3) Choose your DVD / CD drive to boot from, then hit any key to boot from CD.
4) During XP setup, blow away all existing paritions (leave the small 400mb if you ever plan on reinstalling Suse Linux – I did not).
5) Format as NTFS – I used the “Quick” option as it takes forever the other way.
6) Install XP as normal from here forward.
7) Once installed, grab the Broadcom Ethernet driver and install it via CD or SD card:
8) Once you have a working NIC, connect to the internet, activate your copy of XP, and go to the “Windows Update”.
9) From Windows Update, choose “Custom” and install all of the hardware drivers it offers.
11) At this point, everything should be working except sound and HP Quicklaunch button support.
12) Download the KB888111 patch and install for the first part of the sound fix:
13) Download the Vista sound drivers for the Mini-Note from the HP website:
14) Run the install for the file above. It will unzip to a folder of your choosing, try to run, and then bomb because you don’t have Vista.
15) Go to Device Manager, double click on the “?” for sound device, choose Update Driver, and point it at the Vista driver folder unzipped by the above application.
16) At this point, you should have sound when finished.
17) Install the HP QuickLaunch button drivers (it’s under “Official Site 1″):
18) Ignore the popups for new hardware during this install – they will go away on their own.
19) Hit the “Start” button, click “Run”, then type “msconfig”.
20) Once inside msconfig, click the “Startup” tab on the right, and turn OFF “smax4pnp”.
