Disable onboard graphics of my PCChips M825LU motherboard?

Restart your computer.
Enter BIOS-setup mode.
Navigate through the menus to "enable" the onboard audio.

Have you tried entering BIOS? I beliveve that you have to press and hold F1 during boot to enter BIOS. Once in there you should be able to disable onboard video card.

Check your BIOS - there should be a setting in there to disable the onboard video. You shouldn't need to use a jumper to disable this.

It probably is *NOT* a "jumper" setting on the motherboard.

Instead, restart the computer, and press DELETE to enter BIOS SETUP MODE.

Navigate through the menus, and you should find some "enable/disable" setting for the "OnBoard AC97 Sound". Disable, and "save settings", and let the computer reboot.

there are no jumpers to disable the onboard sound you need to enter the bios setup by pressing del as soon as you power up the system once in the bios setup page look for the integrated peripherils and enter that menu then look for via onchip pci device and enter that submenu there you should find the setting for the audio and it will be set to auto or on then you just have to change it to off or disable .Hope this helps

Your N9600GT provides two HDMI out puts for dual display.
Even though you are currently only using one HDMI. Switch your monitor cable to the other HDMI out put. See if you now have display.
Also while in the bios allow, Page 2-27 in manual, Allocate IRQ to PCI set to [Yes]. Page 2-24, Internal Graphics Mode Select, [Disable]

Luck!

If you have not tried to turn off the onboard graphics in the bios then you should do so. When you start your you will be given the option to enter setup( sometimes it is the delete key or one of the F keys }. once you are there simply look for the onboard adapter and disable it there. be sure to save changes before exiting.

Fijate en esta página que tenes los drivers de las PCCHIPS viejitas. Tenés además, que controlar que el jumper JP3 que habilita la placa de red.
Jumper JP3: Enable/Disable Onboard LAN Use this 3-pin jumper to enable or disable the onboard network adapter.

For user BIOS21 & julio1963,
How to enable you're (Add-in AGP video card) & disable the onboard, integrated S3 graphics UniChrome 2D/3D PCI graphics card.
Enter you're bios. Open you're user manual to page 3-13. Integrated Peripherals. Go to, Init display first. Set to AGP.
(Not to PCI). That is all you need to change. The MSI bios will than see you're add in AGP card & automatically disable the PCI S3 graphics, (Onboard) card.

Enjoy!
If I can help you further, feel free to post here.
Please, each user's vote this issue as a fix, if this helped you to get you're bios to see you're new AGP graphics cards.

This is the manual for your motherboard. Page 13 shows you which jump you need to reset to clear your BIOS. The jumper appears to be labeled JBAT1.

Hope this helps!
