CAUTION!
1. Due to the operating system limitation, the actual memory size
may be less than 4GB for the reservation for system usage
under Windows® 8 / 7 / VistaTM / XP. For Windows® OS with 64bit CPU, there is no such limitation. You can use ASRock XFast
RAM to utilize the memory that Windows® cannot use.

ASRock Crashless BIOS
ASRock Crashless BIOS allows users to update their BIOS
without fear of failing. If power loss occurs during the BIOS up-
date process, ASRock Crashless BIOS will automatically nish
the BIOS update procedure after regaining power. Please note
that BIOS les need to be placed in the root directory of your
USB disk. Only USB2.0 ports support this feature.
ASRock OMG (Online Management Guard)
Administrators are able to establish an internet curfew or restrict
internet access at specied times via OMG. You may schedule
the starting and ending hours of internet access granted to other

1.5 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.
Jumper Setting Description
Clear CMOS Jumper
(CLRCMOS1)
(see p.2, No. 21)
Note: CLRCMOS1 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 power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 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 nish updating the BIOS, you must boot up
the system rst, and then shut it down before you do the clear-CMOS action.
Please be noted that the password, date, time and user default prole will be
cleared only if the CMOS battery is removed.
Clear CMOSDefault
If you clear the CMOS, the case open may be detected. Please adjust
the BIOS option “Clear Status” to clear the record of previous chassis
intrusion status.
