Anyway to disable a pci-e slot in the bios?

Hi,

I have a gtx 260 as a dedicated phsyx card, but am pushing my system in terms of power.


I just played through mafia 2 without any problems, but for power concerns, as well as the fact that having the card in my computer reduces the bandwidth of my other card (asus 5970: I think from 16x to 8x), I was wondering if there is anyway of disabling a card in the bios, without having to actually physically remove it.


I know I can disable it in windows, but was wondering if there was a way of selectivily disabling and enabling it in the bios, so that it isn't even fired up apon booting. I haven't searched my motherboard manual yet, but don't remember seeing this as a possiblity. I will check when I get home, but was just wondering if this is something that is remotely possible.

Thanks in advance.
