What is the easiest way to reset my HDR (MDR) BIOS?
When inside the BIOS (CMOS) you will see an option called Load Default BIOS Settings. If you are unable to get into the BIOS (say, you set a password and forgot it) you can pull the Clear CMOS jumper off the motherboard – found between the BIOS EPROM and the battery. Move the jumper over one position. Pull the power cable and let the computer sit for 5 or 10 minutes, then move the jumper back to its original position. BIOS should now be reset. Remember, you still need to modify the BIOS for the HDR (MDR). Note: You can also remove the battery from the mother board. In some cases, you must let the motherboard sit for more than a few hours to allow residual power to be drained. Once drained, the BIOS will revert back to its default setting. Also, if you are taking the time to remove the battery – you might want to just replace it altogether. A drained motherboard battery can cause the BIOS to revert back to its factory default – a show-stopper to be sure. See HDR/MDR Battery Replacement
