Right, where is Bus controller shown, is it under the USB (universal serial bus) heading, if so it is prob looking for the driver SP1 will load.
The Via F6 drivers are for the SATA HDD, so that XP can recgnise them.
The Via Hyperion drivers 4 in 1, are the latest ones for the Via chipset on the MOBO, controls most things.
The latest drivers for all your needs are available for download from the planetAMD64.com, the page needed ishttp://www.planetamd64.com/modules/mx_pafiledb/dload.php?sid=
Use windows drivers,- chipset driver- the Via hyperion is there. All the other stuff, sound Lan , video etc. are downloadable from there
You need to load SP1 and updates, for security alone!
Now a little exercise of you skills, there is a free prog to slipstream SP1 onto a new XP CD, which is bootable, Its really top class, saves eons ot time. and loads drivers and updates as it goes. It also installs the links to internet, my machines are on line half way through the installation, updating themselves. It looks a lot more complicated than it is, if you follow it step by step, you will find it quite easy and well explained. the link is http://www.duspinnst.com/bootcd.htm
your doing OK, nearly there, once SP1 is loaded use live update 3 to complete updates
