ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
Floppy Disk Drive Connector: FDD1
The mainboard provides a standard floppy disk drive connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy
disk types.
IDE Connector: IDE1
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100 controller that provides
PIO mode 0~4, Bus Master, and Ultra DMA 66/100 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.
MSI Reminds You...
If you install two hard disks on one 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.
Serial ATA Connectors controlled by Intel ICH6: SATA1 ~ SATA4
The Southbridge of this mainboard is Intel ICH6, which supports four serial
connectors SATA1 ~ SATA4. SATA1 ~ SATA4 are dual high-speed Serial ATA
interface ports. Each supports 1st generation serial ATA data rates of 150 MB/s.
Four connectors are fully compliant with Serial ATA 1.0 specifications. Each
Serial ATA connector can connect to 1 hard disk device.
MSI Reminds You...
Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data
during transmission.
CD-In Connector: CD1
The connector is for CD-ROM audio connector.
Fan Power Connectors: CPUFAN1/SYSFAN1
The 4-pin CPUFAN1 (processor fan) and 3-pin SYSFAN1
(system fan) support system cooling fan with +12V.
