Note:
*Specifications are subject to change without notice

**The actual Max memory capacity that could be recognized under a 64-bit OS will
be less than 4GB due to the conflict in the memory space of the MMIO mapping.

*** As the operating temperature provided in the specifications is a result of the test
performed in VIA’s chamber, a number of variables can influence this result. Please
note that the working temperature may vary depending on the actual situation and
environment. It is highly suggested to execute a solid testing and take all the
variables into consideration when building the system. Please ensure that the system
runs well under the operating temperature in terms of application.

22

Installing memory modules

Step 1
Locate the SODIMM slot in the mainboard and align the notch on
the SODIMM with the memory slot.

Step 2
Insert the SODIMM module at a 30 degree angle. Then push the
SODIMM down until it snaps into the locking mechanism.

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 (JM1) on pins 2 and 3 while the system is off.
Return the jumper to pins 1 and 2 afterwards. Setting the jumper
while the system is on will damage the mainboard. The default
setting is on pins 1 and 2.

Caution:

Except when clearing the RTC RAM, never remove the cap from the CLEAR_CMOS
jumper default position. Removing the cap will cause system boot failure. Avoid
clearing the CMOS while the system is on; it will damage the mainboard.

INSTALLING THE P830-A

Step 1

Align the CON1 and CON2 connectors on the P830-A with the
VGA_USB1 combination pin header block and LAN pin header
block on the EPIA-P830, respectively. In the figure below, the
dotted rectangles represent the CON1 and CON2 connectors on
the bottom side of the P830-A companion card.

28

Step 2

Then gently press down until the pins on the EPIA-P830
mainboard have been fully inserted into the CON1 and CON2
connectors of the P830-A companion card.

Step 3

Secure the EPIA-P830-A to the EPIA-P830 with two screws.

29

INSTALLING THE P830-B

Step 1

Align the CN6 connector on the EPIA-P830 with the CN2
connector on the P830-B. Then gently insert the CN6 connector
into the CN2 connector until the CN6 connector is fully inserted.

system configuration.

When a supervisor password is set, the User Access Level and
Password Check options will be unlocked.

Password Check

This feature is compulsory when the Change Supervisor Password
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.
