Disable onboard sound in BIOS, OS Win XP

I would like to disable the onboard sound device on my Compaq 5660. I purchased a Philips 5.1 sound card and would like to use it on my system. When I contacted Philips Tech service they said I needed to disable the onboard sound through the BIOS setup. I have the home Win XP installed on the pc. Disabling the device through XP doesn't work. I need to disable the hardware setting.

Thanks in advance,

You'll have to enter the CMOS (System) setup and find the setting to disable the onboard sound in there.

I can't remember right now which key Compaqs use to access the CMOS setup - it' either F1, F2 or F10 - press the key as the system is first starting up and the blinking cursor jumps from the upper left corner to the upper right corner of the screen.

 

What ComPaq told me

They gave instructions to me for eliminating the on board installed video then reinstalling a PCI video in Windows XP give me a shout, I am fairly certain it would be the same technique, I can e-mail it, or post, either way.

But it is also far more involved than what Cliffh says.
In addition to Bios changes, you have to change within the Registry, ANd the Device manager. This is prior to booting with the actuall new item plugged in.

 

i just installed a new video card in my compaq 5204. to get back into windows, i had to boot in safe mode, remove the on-board video from device manager, and reboot. it finds new hardware( the on-board video), but i cancel it. i could use the info you got from compaq. i found nothing in my manual about disabling on-board video. i don't care if you e-mail it to me, or post it. whatever you would like to do.
