You almost have it right. There is one more patch to Windows XP you must install before the Conexant High Definition Audio driver and possibly the onboard modem driver will work.

Read about kb888111.exe file from
http://support.microsoft.com/kb/888111/en-us

But kb888111.exe is not available at that link. It is here:
http://geekswithblogs.net/lorint/archive/2006/06/11/81540.aspx

Then re-install Conexant High Definition Audio Driver, and probably the modem driver as well since this usually uses the audio driver.

I don't want to get your hopes up but I've got audio working on a C700T I put XP on for my sister. (No way this thing could run Vista...its absolute bare-spec, with the exception of a bump to 1gig RAM) It was a pain, no doubt. I don't have links to the SoftPaq files but here's the ones you want:
MS-UAA: 33867
Audio: SP34200
Modem: SP33839

Install the Windows UAA pack (~50meg) to enable support for the "HighDef Audio"...gotta do this first...I believe I restarted after installing this. You'll notice it changes the names of the unknown-devices in device manager.

Using devicemanager, update driver on the HighDefAudio unknown item. Use drivers from SP34200. You want to avoid having it auto search etc...all of this fails. Just get to the dialog where you can say "have disk". I ignored any of the "compatibility" messages that popped up and proceeded with driver-update.

Rinse/Repeat to install the modem using SP33839

My laptop also had a remaining "unknown device"...this, I believe, is related to the HP Soft Keys not being installed. They've pulled this driver for now, as it has a security issue. I saw on their website that they expect to have version 6.4 released later in January2008.

Just a side note; I had the audio working with SP35682 (following directions on an HP forum) but had terrible issues when trying to plug in headphones. I "fell-back" to the SP34200 listed above and have no issues with headphones. You'll quickly notice that the laptop speakers are junk...however, my sennheisers actually sounded pretty good through the headphone output.

There's more discussion at this link: (check towards the very bottom of comments)
http://www.notebooks.com/2007/11/11/...ebook-for-349/
not sure if the black-friday model might be similar to your model...he claims to use different drivers. But the SP driver-numbers I gave above were the ones that worked for me. ("CustomBuilt" by hp...a C700T designation...Celeron530Proc, 1gigRam,80gigHD, 965 mobile chipset, x3100 graphics)

Downgraded Vista to XP from Presario c700


A lot of times, when downgrading from factory installed operating systems, you run into driver issues because they arent written for any other operating system than what they offer. My best recommendation is to google the component name and desired operating system into google (like AC97 xp driver or ATI Radeon 1300m xp driver). This will take you to a lot of 3rd party sites that have drivers to work for those specific devices. Same thing happened to me with my dell xps 1530. Came with vista, but i wanted xp. Had to scour the dell site to find drivers, but eventually found them. Once you find them, burn them to a disk for later reference.
