I managed to get Windows Vista build 5472 installed on a Sony Vaio VGN-SZ140P laptop. The first run was abysmal, Vista installed a default VGA driver and almost nothing worked, I couldn't click on the Start menu, couldn't install new drivers, it was bad. Eventually I managed to reboot Windows Vista and things were much better the second time around.
I managed to switch my video to the nvidia GeForce Go 7400 card (instead of the motherboard Intel 945GM chipset) but I had to manually download the drivers from the Sony web-site.
The built-in video camera is not working as Vista does not support the camera natively and Sony's Windows XP do not work on Vista. As a result, I do not have video nor a working microphone. Major bummer for any hopes to use a VOIP and IM application.
Without a microphone, I won't be able to try out Vista's speech recognition interface - major bummer.
I managed to install the Bluetooth drivers from the Sony website, but none of the included Sony Bluetooth applets work (Bluetooth Settings, Bluetooth Information Exchange, etc). In effect, this renders bluetooth worthless on the laptop.
I have not been able to install the Intel 945GM video drivers. I can only use the faster, but more power hungry, nvidea video card - this is going to hurt battery performance.
The sony drivers for the memory card reader seem to work fine, but they must be manually installed - no supported drivers are included with this build of Windows Vista.
Windows Vista recognized the fingerprint scanner, but there are no applications that makes use of it. Sony's Protector Suite QL does not work on Vista (as expected). As a result, you loose the ability to login to Windows and other sites using the fingerprint reader.
Windows Device Manager still shows 4 devices as un-recognized (maybe the 1394 interface, a "UGX" device - whatever that means, and 2 others).
That's as far as I am going to explore tonight. While Windows Vista is working, and in fact I am writing this blog entry on my Vista machine using Microsoft's own new Windows Live Writer, I would not say that Vista can be used as a primary system on this Sony laptop.
Windows Vista, so far, lacks too many drivers to make this laptop truly operational.
