Jumpers Setup - ASROCK STX-1500 User Manual

2.5 Jumpers Setup

The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is "Short". If no jumper cap
is placed on pins, the jumper is "Open". The
illustration shows a 3-pin jumper whose
pin1 and pin2 are "Short" when jumper cap
is placed on these 2 pins.
Clear CMOS Jumper
(3-pin CLRMOS1)
(see p.8, No. 24)
Note: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn off the computer and unplug
the power cord from the system. After waiting for 15 seconds, use a jumper
cap to short pin2 and pin3 on CLRMOS1 for 5 seconds. However, please do
not clear the CMOS right after you update the BIOS. If you need to clear the
CMOS when you just finish updating the BIOS, you must boot up the system
first, and then shut it down before you do the clear-CMOS action. Please be
noted that the date, time and user default profile will be cleared only if the
CMOS battery is removed.
