IDE Connectors: IDE1 & IDE2 The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/133 controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 33/66/100/133 function. You can connect up to four hard disk drives, CD-ROM, 120MB Floppy and other devices. The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a Slave drive. You must configure second hard drive to Slave mode by setting the jumper accordingly. IDE2 can also connect a Master and a Slave drive. MSI Reminds You... If you install two hard disks on cable, you must configure the second drive to Slave mode by setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper setting instructions. Chassis Intrusion Switch Connector: JCASE1 This connector is connected to 2-pin connector chassis switch. If the 2 GND 1 C I NTRO Chassis is open, the switch will be short. The system will record this status. To clear the warning, you must enter the BIOS setting and clear the status. Fan Power Connectors: CPU_FAN/SYS_FAN The CPU_FAN (processor fan) and SYS_FAN (system fan) support system cooling fan with +12V. They support three-pin head connector. When connecting the wire to the Control SENSOR +12V GND connectors, always note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. MSI Reminds You... Always consult the vendors for proper CPU cooling fan. 8

If you install two hard disks on cable, you must configure the second drive to Slave mode by
setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper
setting instructions.
Chassis Intrusion Switch Connector: JCASE1
This connector is connected to 2-pin connector chassis switch. If the
Chassis is open, the switch will be short. The system will record this status. To clear the warning,
you must enter the BIOS setting and clear the status.
Fan Power Connectors: CPU_FAN/SYS_FAN
The CPU_FAN (processor fan) and SYS_FAN (system fan)
support system cooling fan with +12V. They support
three-pin head connector. When connecting the wire to the
connectors, always note that the red wire is the positive and should be
connected to the +12V, the black wire is Ground and should be connected to GND. If the
mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed
fan with speed sensor to take advantage of the CPU fan control.
