First unless you have some compelling reason just go to the BIOS and disable SATA.
1. F10 | System Config | SATA Native Support | [Disable] | [Save]
2. Load XP
3. Load XP SP 2
4. Go to the link below and download the drivers for the dv6205
5. First you are going to need the Network Card (ntelPro100) drivers or you aren't going to be able to do jack. Oh, and you are going to have to put it on a CD from another computer because your network card isn't working and neither is your USB, so forget the thumb drive.
6. Most of the drivers that I loaded were from the dv9000 site (I am assuming they have the same board).
7. (dv9000) Network, Video, Chipset, Card Reader, Wireless (dv6000)FaxModem, Audio
8. With the Audio load the 'Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio' before the 'Conexant High Definition Audio Driver'
9. Don't bother with the Bluetooth or TV Card drivers the dv6205 has none.
10. You'll notice between the dv6000-dv9000 site that most of these are the same downloads.
11. Any error corrections or additions please post.
I think I have located the drivers for the HP dv6205
dv9000 drivers:

XP is fully loaded and works great.
Oh, and a special thanks to HP and MS for making life difficult for ALL OF US!
