Hello,

I have a p31-ds3l Motherboard by gigabyte and i was wondering if anyone knows how i can stop the bios from adding external hard drives to my boot order. I go in and set it and when i unplug it and replug it in and reboot its added back to my boot order.

Flaw in board maybe?

are you pressing F10 before exiting?

DO you have externals connected?

I do not think there is a way to delete something that is in the BIOS I/O menus..It is there for a reason..

Just make sure that it is not highlighted as your first boot device..

When you unplug/replug your PSU-- you probably reset the BIOS configuration.There is all kinds of info on BIOS available-- watch out for so-called bios-tweaking apps--you can really mess things up if you are not careful.

well im not pressing any keys as it is in my closet as a server that i remote desktop into. Also, I have removed the externals and than it seems to fill the boot device number 3 although i made it disabled.

The power supply being unplugged shouldnt matter. It has a bios battery for that reason.

Batteries wear out, sir.
The battery power is what allows the BIOS customizations to carry-over to the next boot-- if the battery is weak-- the settings are lost.

I know the battery is good. The motherboard is 2 weeks old and i have it over clocked and it says its overclocked every time it boots so i know the battery works or else the cpu setting would reset back to default.
