This RTC needs power...only a little bit but more then nothing. For that there is a battery holder (oh damn, I fear, this term is german English... ;) on the motherboard, which can easily be identified, because it is about of the size of two Euro coin and an silvery coin is in there (visible from the outside). The similarity of the shape of a coin and and a coin cell gave the latter its name. BUT! Dont pull that out before you got a new one! Most often these cells are lithium batteries, which name starts with CR.. . On my motherboard there is a CR2032. But this should be mentioned in the manual of your mitherboard (and if that get lost you will find a pdf of that on the net somewhere). If you got a new cell, shutdown the computer, remove the mains plug from the back and switch the PC on again (no joke). This will empty any capacitor in the mains adapter and on the board. Touch the metal case of the PC (or if it is plastic touch the outer shell of an USB jack (**NOT** the inside), where you can easily reach it (in most cases on the back of the PC instead of the front). This will discharge any static electricity. Otherwise grub and the coin cell become a minor problem... ;) Check the manual how to remove the BIOS coin cell. Do it carefully but do it not excessive slow. Insert the new battery (remove it from the package before you remove the old cell) as described in the manual. If you are quick enough chance are given that all settings of the BIOS will survive the short no-power situation. Boot the PC again. If you didnt configure ntp for your PC and the time/date of the PC didn't survive the short power fail of the coin cell swap, set the date by hand, emerge net-misc/ntp, configure it and run it by hand to set time/date correctly. If the PC does not boot: Install grub as Dale mentioned. A missing stage2 bootloader may be the reason, why grub hangs while looking for it. If the problem went away after installing grub (and with it a new stage2 bootlaoder) the missing stage2 bootloader is the first candidate for being the reason of the problem. Good luck! Best regards, Meino

At least none of my mainboards has such a feature. You could search in your mainboard manual about that. Another way to save your BIOS settings is to make a photo from every BIOS page with a camera or phone. But don't forget to scroll through the pages if they do not fit entirely on the screen. It should not take more than a few minutes to restore the BIOS settings with the help of these photos. Regards wabe
