Jumpers Setup - ASROCK K7S8X User Manual

2.7 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 the pins, the jumper is
"OPEN". The illustration shows a 3-pin
jumper whose pin1 and pin2 are "SHORT".
Jumper
FSB_SEL0
(see p.7/p.8 item 9)
FSB_SEL1
(see p.7/p.8 item 10)
Note: The setting of the CPU front side bus frequency of this motherboard is by
means of the adjustment of jumper-setting. Please follow the figures above
to set the CPU front side bus frequency.
PS2_USB_PWR1
(see p.7/p.8 item 1)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1
(see p.7/p.8 item 25)
JL1
(see p.7/p.8 item 24)
Note: When you connect speakers in back panel and front panel at the same time,
1. If the jumpers JL1 and JR1 are short (see fig. 1), both front panel and
rear panel audio connectors can work.
2. If both jumper caps on JL1 and JR1 are removed (see fig. 2), only front
panel audio works.
However, it requires your front panel to support the function.
