Computer motherboards are complex.
The reasons you'd want to reset the BIOS on your MS-6741 motherboard range from a lost BIOS password to bad settings that are incompatible with your hardware and prevent you from booting the computer. Sometimes your BIOS becomes corrupted and you need to go back to the default settings and start over. To start with a fresh slate, you need to clear the CMOS memory of your motherboard and reset it to the factory defaults.
Instructions
1. Reset the BIOS within the Setup options. To get to the BIOS Setup, turn on your computer and press "Delete" while it is booting; you may have to press it repeatedly until the computer enters the BIOS Setup. Press "F7" to set it to the default values. When the window appears asking you to press "Enter" or "Escape," press "Enter." Press "F10" to save your changes and exit. It will automatically reboot your computer.
If this hasn't solved your problem or you can't get the BIOS to boot, try the physical reset.
2. Turn off the computer. If there is a switch on the power supply, turn that off as well. Wait 15 minutes for the capacitors in the motherboard to discharge. Remove your shoes and socks and put on a grounding strap wrist band attaching the wire to the bare metal on the case. Touch the case before touching the motherboard.
3. Open the computer; usually, this involves unscrewing or sliding one side of the computer case open. Look at the motherboard and orient yourself. Find the small switch with a jumper labeled JBAT1. Jumper switches are small trios of pins, about one quarter-inch wide, two of which will have a rectangular plastic jumper capping them. The JBAT1 switch on the MS-6741 is on the lower right-hand side of the motherboard if your I/O ports are on the upper left.
4. Note where the jumper is currently set over the pin labeled 1 and the middle pin. You will need to return it to this setting at the end.
5. Lift the plastic JBAT1 jumper straight up using the needle-nose pliers, removing it from the pins, and put it over the pin labeled 3 and the middle pin. Press it in place and release the pin from the pliers.
6. Restart your computer. Make sure you haven't left the pliers or any other foreign object inside the case before restarting.
7. Power down the computer, again waiting 15 minutes for the board to discharge. Reset the jumper on the JBAT1 switch to the pin marked 1 and the middle pin. Restart your computer.
8. Disconnect your wrist strap and close the case.
