CPU
The VIA EPIA-M Mini-ITX Mainboard includes an embedded VIA Eden Processor or VIA C3
TM
E-Series Processor. The CPUFAN (CPU fan) and SYSFAN (system fan) run on +12V and maintain system cooling. When connecting the wire to the connectors, always be aware 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. Both CPU and System fan connectors have sensors to detect fan speed, but the power fan does not have a sensor. FAN3 is an additional FAN connector.

Memory Module Installation
The VIA EPIA-M Mini-ITX Mainboard provides one 184-pin DIMM slot for DDR266 SDRAM memory modules.
DDR SDRAM Module Installation Procedures
1. Push the white retaining latches at either end of the DIMM slot outwards.
2. Align the DDR SDRAM module with the corresponding notches on the
DIMM slot. The modules will only fit if placed in the correct position.
3. With both hands, press the DDR SDRAM module down into the DIMM
slot so that the white retaining latches rotate up and secure the module in place (see picture below).

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 functions. You can connect up to four hard disk drive, CD-ROM, LS-120 and other devices. These connectors utilize the provided IDE hard disk cable.
IDE 1
IDE 2
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 the 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.
If you install two hard disks on a single cable, you must set the jumper on the second hard disk drive to slave mode. Please refer to the hard disk documentation supplied by hard disk vendor for the jumper settings.
