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.

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/Serial ATA RAID Connectors controlled by VT8237/8237R:
SATA1, SATA2
The southbridge VIA VT8237/8237R provides a hybrid solution that combines two independent SATA
ports for support of up to two Serial ATA (Serial ATA RAID) drives and supports
RAID levels 0 or 1 for easy management of the storage subsystems. Both
connectors support 1st generation serial ATA data rate of 150 MB/s and are
fully compliant with Serial ATA 1.0 specifications.
Fan Power Connector: CFAN1/SFAN1/PWFAN1
The CPUFA1 (processor fan) supports system cooling fan with +12V. It supports 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.

§
Always consult the vendors for proper CPU cooling fan.

CFAN1 supports the fan control. You can install Core Center utility that will automatically control the
CPU fan speed according to the actual CPU temperature.
CD-In Connector: J4
The connector is for CD-ROM audio connector.
