[. . . ] The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. 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 2 pins on CLRCMOS1 for 5 seconds. 17 J1 Jumpers (see p. 10 No. 28) E D C B A 1 Note: The set of J1 jumpers are only for advanced users to adjust the multiplier of CPU. However, the system will work well without the adjustment of multiplier. You do not have to adjust the multiplier for normal usage.

Please understand that ASRock does not guarantee and support the adjustment of multiplier. These jumpers setting may not apply to all multiplier-locked or even some unlocked AMD CPU. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU. 18 2. 6 Connectors Connectors are NOT jumpers. Placing jumper caps over the connectors will cause permanent damage of the motherboard! Connector FDD Connector (33-pin FLOPPY1) (see p. 10 No. 15) Pin1 Figure Description FLOPPY1 the red-striped side to Pin1 Note: Make sure the red-striped side of the cable is plugged into Pin1 side of the connector. 7) PIN1 IDE1 PIN1 IDE2 connect the black end to the IDE devices connect the blue end to the motherboard 80-conductor, ATA 66/100/133 cable Note: If you use only one IDE device on this motherboard, please set the IDE device as “Master”. Please refer to the instruction of your IDE device vendor for the details. Besides, to optimize compatibility and performance, please connect your hard disk drive to the primary IDE connector (IDE1, blue) and CD-ROM to the secondary IDE connector (IDE2, black). 17) 1 GND P+4 P-4 USB_PWR USB_PWR P-5 P+5 GND DUMMY There are 4 default USB 2. 0 ports on the rear panel. If the rear USB ports are not sufficient, this USB 2. 0 connector is available to support 2 additional USB 2. 0 ports. This connector supports an optional wireless transmitting and receiving infrared module. Infrared Module Connector (5-pin IR1) (see p. 10 No. 19) 1 IRTX +5V DUMMY GND IRRX 19 Internal Audio Connectors (4-pin CD1, 4-pin AUX1) (CD1: see p. 10 No. 27) AUX1 CD1 These connectors allow you to receive stereo audio input from sound sources such as a CDROM, DVD-ROM, TV tuner card, or MPEG card. This is an interface for front panel audio cable that allows convenient connection and control of audio devices.

Please refer to below descriptions for the details of these four options: [Enabled] - Enables support for legacy USB. [Disabled] - USB devices are not allowed to use under legacy OS and BIOS setup when [Disabled] is selected. If you have USB compatibility issue, it is recommended to select [Disabled] to enter OS.
