Password Clear (J9C1-A); Clear Cmos (J9C1-A); Bios Setup Access (J9C1-B); Bios Recovery (J8A1) - Intel AN430TX - Motherboard - ATX Technical Product Specification

1.13.2 Password Clear (J9C1-A)

Use this jumper to clear the password if the password is forgotten. The default setting is pins 1 -2
(password enabled). To clear the password, turn off the computer, move the jumper to pins 2-3,
and turn on the computer. Then, turn off the computer and return the jumper to pins 1-2 to restore
normal operation. If the jumper is in the 2-3 position (password disabled), you cannot set a
password.

1.13.3 Clear CMOS (J9C1-A)

This jumper resets the CMOS settings to the default values. This procedure must be done each
time the BIOS is updated. The default setting for this jumper is pins 4 -5 (keep CMOS settings).
To reset the CMOS settings to the default values, turn off the computer, move the jumper to
pins 5-6, then turn on the computer. When the computer displays the message "NVRAM cleared
by jumper," turn off the computer and return the jumper to pins 4-5 to restore normal operation.

1.13.4 BIOS Setup Access (J9C1-B)

This jumper enables or disables access to the Setup program. The default setting is pins 1-2
(access enabled). To disable access to the Setup program, move the jumper to pins 2-3.

1.13.5 BIOS Recovery (J8A1)

This jumper lets you recover the BIOS data from a diskette in the event of a catastrophic failure.
The default setting is pins 1-2 (normal operation). To recover the BIOS, turn off the computer,
move the jumper to pins 2-3, then turn on the computer to perform BIOS recovery. After recovery,
turn off the computer and return the jumper to pins 1-2 to restore normal operation. See
Section 3.1.12 for more details.

1.13.6 Processor Voltage (J6M1)

This jumper sets the output of the onboard voltage regulator. For processors that require Standard
voltage, place the jumper on pins 1-2. For processors that require VRE voltage, place the jumper
on pins 2-3. Voltage specifications are as follow:
Standard = 3.3 - 3.465 V
VRE = 3.465 - 3.63 V
CAUTION
When installing a processor in the motherboard for the first time or upgrading to a new processor,
check the processor's documentation for the correct voltage setting. Operating the processor at
the wrong voltage can cause unreliable performance.
