I upgraded my presario f750 from vista to xp. Most of the drivers I've found except coprocessor, ethernet, and base system device. Searching for the above drivers.

Sometimes , when a Computer's OS is upgraded, form the original OS, you will find "Unknown Devices" in Device Manager. "Coprocessor" is common. Usually it's the Card Reader, try installing the driver for the Card Reader, Windows 7 32 or 64bit what ever OS Windows 8 is. You can find the drivers here, choose your OS 32 or 64bit, try Driver-Storage, Realtek USB 2.0 Card Reader, you must change compatibility of the Win 7 driver: Card Reader driver: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&lc=en&dlc=en&product=3927357 Change driver compatibility: http://www.eightforums.com/tutorials/6832-compatibility-mode-use-windows-8-a.html

See my post on your previous question.

This is the 3rd post, see my post

The ‘Base System Device’ relates to the cardbus of the laptop. To resolve this issue download and install the driver from HP website.

i don't have driver for biometric coprocessor, base system device

Hi,

Try letting Windows update detect and install the coprocessor driver for you.
You may have to perform the Windows update a couple of times before the device is detected.

When you start windows update it will give you a list of software and drivers that are available, you will in the list that there are optional updates available. Check there to see if the coprocessor driver is there and install everything except for the language packs.

Hopefully this will resolve the problem for you.


Good luck.

You need to download the drivers from the Compaq/HP WEB support/download page. Make sure you select your model laptop and the Vista Windows version of the drivers you require and install them. Use this link to download the drivers

there is a chance that your onboard audio was made after xp days, and there has never been an xp driver released, but you'd figgure the audio output would be disabled as well. You may want to purchase a usb audio device which has a microphone input, musical instrument stores usually carry a wide selection of usb audio input devices, if you cannot find a suitable device at a retail electronics store.
