I recently switched from vista to xp pro and am having a problem with a number of drivers. I have three "Base System Drivers" that are needed and i have no clue what they are. Secondly i can not get the NVIDIA geforce graphics card to work. The computer's p/n=KN854UA#ABA. Any assistance would be greatly appreciated.

The 3 missing base system devices are part of your Ricoh 5-1 card reader.
Here are the XP drivers for those:
I recommend you install the nForce chipset driver first and reboot:
Then try reinstalling the video driver:

That is definitely the missing chipset driver:
Not sure if it works for notebooks, but I suggest you go to the nVidia site and let it do the automatic scan and see if it gives you a driver: (option 2)
Select the motherboard driver search first. Then the graphics.

I finally was able to get the graphics card to work, thanks for the help. I am still having problems finding the drivers for "unknown device", "coprocessor", and "ethernet controller". any suggestions?

Like I posted above, it is this driver you need that will take care of the coprocessor and network controller. If it doesn't work, I don't know what to tell you.
The only other thing you can try is to manually update the driver by clicking on the missing device in the device manager, click on the driver tab. Click on update driver, choose the manual method and browse to the Folder C:\SWSETUP\sp33411 and see if it loads the drivers that way.
For the unknown device...click on that in the device manager. Click on the details tab. Post the top string of characters you see. Those identify the manufacturer of the missing device and the device type and model. With that info, I can try and find the driver for you.
I am 99.99% sure the other missing devices need that nForce chipset driver.

You still need the chipset driver. Nothing will work right until you get it. You have the dv6809wm which needs the nForce 730a chipset drivers for Windows XP here:
The driver linked above in the prior post is for the dv6499 and below models only.

Huffer has you fixed up with Chipset. For the 'unknown' it is probably HP Quick Launch. Your DV6809wm is covered in Part 2 of the XP Downgrade Guide
******Clicking the Thumbs-Up button is a way to say -Thanks!.******
