(2) Hard Disk Connectors: IDE1/ IDE2 The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO Mode 0~4, Bus Master, and Ultra DMA 33/ 66/ 100/ 133 functionality. It has two HDD connectors IDE1 (primary) and IDE2 (secondary). The IDE connectors can connect a master and a slave drive, so you can connect up to four hard disk drives. The first hard drive should always be connected to IDE1. (3) Peripheral Component Interconnect Slots: PCI1-3 This motherboard is equipped with 3 standard PCI slots. PCI stands for Peripheral Component Interconnect, and it is a bus standard for expansion cards. This PCI slot is designed as 32 bits. (4) Accelerated Graphics Port Slot: AGP1 Your monitor will attach directly to that video card. This motherboard supports video cards for PCI slots, but it is also equipped with an Accelerated Graphics Port (AGP). An AGP card will take advantage of AGP technology to improve video efficiency and performance, especially with 3D graphics. (5) Communication Network Riser Slot: CNR1 (optional) The CNR specification is an open Industry Standard Architecture, and it defines a hardware scalable riser card interface, which supports modem only. (6) Clear CMOS Jumper: JCMOS1 This jumper helps you to clear the Real Time Clock (RTC) Ram in CMOS. You can erase the CMOS RTC Ram data to clear the CMOS memory of date, time, and system setup parameters. JCMOS1 Assignment Pin 1-2 Close Normal Operation (default) 1 Pin 2-3 Close Clear CMOS Data 1 * Clear CMOS Procedures: 1. Remove AC power line. 2. Set the jumper to "Pin 2-3 Close". 3. Wait for five seconds. 4. Set the jumper to "Pin 1-2 Close". 5. Power on the AC. 6. Reset your desired password or clear the CMOS data. (7) Wake On LAN Header: JWOL1/JWOM1 ( optional) This connector allows you to connect to a LAN card with Wake On LAN function. You can wake up the computer by remote control through a local area network. Pin Assignment 1 +3.3V Standby Voltage 1 2 Ground 3 Wake up 13 English
