The mainboard provides connectors to connect to FDD, IDE HDD, case, LAN, USB
Ports and CPU/System FAN.
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.
Connectors
FDD1
Fan Power Connectors: CPUFA1/SYSFA1
The CPUFA1 (processor fan) and SYSFA1 (system fan) support system cooling fan
with +12V. It supports three-pin head connector. When connecting the wire to the
connectors, always take note that the red wire is the positive and should be con-
nected 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 spe-
cially designed fan with speed sensor to take advantage of the CPU fan control.
MSI Reminds You...
1. Always consult the vendors for proper CPU cooling fan.
2. CPUFA1 supports the fan control. You can install the PC Alert utility
that will automatically control the CPU fan speed according to the
actual CPU temperature.CPUFA1

Hard Disk 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 (reserved for future
BIOS) and other devices.
IDE1 (Primary IDE Connector)
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 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
IDE1 IDE2
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.

Serial ATA Connectors controlled by VT8237: SATA1 & SATA2 (for
KM4AM only)
The Southbridge of the KM4AM mainboard is VIA VT8237 which supports two serial
connectors SATA1& SATA2.
SATA1 & SATA2 are dual high-speed Serial ATA interface ports. Each supports 1
st
generation serial ATA data rates of 150 MB/s. Both connectors are fully compliant
with Serial ATA 1.0 specifications. Each Serial ATA connector can connect to 1 hard
disk device.

Front USB Connectors: JUSB2 & JUSB3 (JUSB3 is optional)
The mainboard provides one standard USB 2.0 pin headers JUSB2 and one optional
standard JUSB3. USB 2.0 technology increases data transfer rate up to a maximum
throughput of 480Mbps, which is 40 times faster than USB 1.1, and is ideal for
connecting high-speed USB interface peripherals such as USB HDD, digital cameras,
MP3 players, printers, modems and the like.
