Power Supply
The mainboard supports ATX power supply for the power system. Before inserting the power supply
connector, always make sure that all components are installed properly to ensure that no damage will
be caused. Power supplies of 300watt (and up) are highly recommended for system stability.
ATX 20-Pin Power Connector: JWR1
This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug of the power
supply is inserted in the proper orientation and the pins are aligned.
Then push down the power supply firmly into the connector.
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 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.
