vista to xp downgrade

Hello. I have a hp media center m8124n with Vista Ultimate on it. I have made the proper backup of Vista and now I have installed Windows XP Media Edition, I have been able to install every driver except 3 (USB Wireless 802.11 b/g Adapter, USB Device, and the most inportant Ethernet Network Controller) can any one tell me if these even exist, and if so where I can get them. I have looked for the drivers for 2 days now, worst comes to worst I have my Vista backups.

Thankyou for any and all help.

This is your motherboard: http://h10025.www1.hp.com/ewfrf/wc/...82&lc=en&cc=us&dlc=en&product=3445425&lang=en
It has an NVidia chipset with RealTek HD ALC888 audio.
Here's your drivers:

You can also try this for the chipset if the above doesn't work: http://www.majorgeeks.com/Nvidia_nForce4_Driver_32-Bit_d4489.html
I can't help you with the wireless without knowing the maker and the model or chipset. Download and run Unknown Devices and use that info to track down the driver. if you need help, post the info from Unknown Devices and we'll try to help...
