2.8. Clear CMOS Jumper

The onboard CMOS RAM stores system configuration data and has an onboard battery power supply. To
reset the CMOS settings, set the jumper on pins 2 and 3 while the system is off, and then return the
jumper to pins 1 and 2 afterwards. Setting the jumper while the system is on will damage the board. The
default setting is on pins 1 and 2.

Step 4

Push down until the memory module snaps into place. The memory slot has two locking mechanisms that
will click once the memory module has been fully inserted.

Step 5

Flip over the heatsink/heat spreader. Remove the plastic cover of the thermal pad of the memory and
chipset.

Step 6

Apply the thermal grease/paste onto the surface of the CPU. Then align the heatsink/heat spreader over
the mounting holes on the VIA ETX-8X90 module.

Figure 20: Heatsink/heat spreader’s mounting holes on VIA ETX-8X90 module

Step 7

Gently install the heatsink/heat spreader. Make sure to install it in proper orientation. The thermal pads
underneath the heatsink/heat spreader should position above the memory and chipset respectively.

autonomously determine the appropriate PIO mode for the hard drive. If a manual setting is preferred,
then be sure the correct PIO mode of the hard drive is used. It is not recommended to set the PIO mode
higher than what the hard drive manufacturer states.

4.6.2.1.2. DMA Mode

The DMA Mode has four possible settings: Auto, SWDMAn, MWDMAn and UDMAn. If a manual setting is
preferred, then be sure the correct DMA mode of the hard drive is used.

option is set. The user will have up to
three chances to enter the correct password before the BIOS forces the system to stop booting. If the user
does not enter the correct password, the keyboard will also lock up. The only way to get past this is to
do a hard reboot (i.e., use the system reset button or cut off the power to the system). A soft reboot (i.e.,
Ctrl+Alt+Del) will not work because the keyboard will be locked. This feature has two options.
