Well, the "famous flavours" of Linux (let's say, Debian, Ubuntu, Fedora, CentOS, Arch) are reasonably likely to have broad enough support going on that they all have a decent chance of including suitable drivers for old-ish laptops. <br>
<br>It's worth taking a peek at a Linux Laptops site.<br>I see several entries for the DV9000T <<a href="http://www.linux-on-laptops.com/hp.html">http://www.linux-on-laptops.com/hp.html</a>><br><br>That suggests that Fedora and Mandriva are distributions that people have used, albeit with old-ish versions, back around 2006.<br>
<br>For laptops, it's well worth looking to resources like <a href="http://linux-on-laptops.com">linux-on-laptops.com</a>.<br>
