Going hunting (ob graphics)

[demon]

As some will know I've decided to add a graphics card to my computer and I have got confirmation that it will be arriving sometime tomorrow which will mean that as soon as it's installed I'm going to have to go hunting in the BIOS so that I can turn off the on board graphics chip but I don't know where to start looking and the only option I've seen is the one that stated the amount of system memory that is used by the graphics chip and I know that won't help as the on board chip will still (probably) be detected by windows when I start up everytime.
Any pointers on where I can look for this off switch.

Oh and I can probably guess that this will be a correct installation procedure.....

Remove all power connections (and unplug from mains as well) and remove side panel
Insert new graphics card (remembering to remove the blanking plate first) and make sure that it is seated properly and is secure.
Close case reconnect to mains and turn on (with the monitor still connected to the motherboard) and with hope it'll fire back up.
Once in windows install new drivers and any other software that is supplied whilst removing any offal that is no longer needed and then shut down.
Connect monitor to graphics card and start up this would be to make sure everything is working the way it should and if it does remove all the drivers for the on board graphics and then restart again.
And by now it'll be time to go hunting in the BIOS to completely kill the on board graphics.
