5.1. Installing into a Chassis
The EPIA-M720 can be fitted into any chassis that has the mounting holes for
compatible with the standard Mini-ITX mounting hole locations. Additionally,
the chassis must meet the minimum height requirements for specified areas of
the mainboard. If a riser card module is being used, the chassis will need to
accommodate the additional space requirements.
5.1.1. Suggested minimum chassis dimensions
The figure below shows the suggested minimum space requirements that a
chassis should have in order to work well with the EPIA-M720.
Figure
Figure 39

Each side of the mainboard should have a buffer zone from the internal wall
of the chassis. The side of the mainboard that accommodates the I/O coastline
should have a buffer of 1.00 mm. The side on the opposite end of the I/O

the I/O coastline should have at least a 10.00 mm buffer.
For the side that is close to the PCI slot, the buffer should be at least 100.00
mm if a riser card module will be used.
5.1.2. Suggested minimum chassis height
The figure below shows the suggested minimum height requirements for the
internal space of the chassis. It is not necessary for the internal ceiling to be
evenly flat. What is required is that the internal ceiling height must be strictly
observed for each section that is highlighted. The highest part of the ceiling
will be above the PCI slot.

This option is for setting a password for entering BIOS Setup. When a
password has been set, a password prompt will be displayed whenever BIOS
Setup is run. This prevents an unauthorized person from changing any part of
your system configuration.
There are two types of passwords you can set. A supervisor password and a
user password. When a supervisor password is used, the BIOS Setup program
can be accessed and the BIOS settings can be changed. When a user
password is used, the BIOS Setup program can be accessed but the BIOS
settings cannot be changed.
To set the password, type the password (up to eight characters in length) and
press <Enter>
<Enter>. The password typed now will clear any previously set
<Enter><Enter>
password from CMOS memory. The new password will need to be reentered
to be confirmed. To cancel the process press <Esc>
To disable the password, press <Enter>
<Enter> when prompted to enter a new

Additionally, when a password is enabled, the BIOS can be set to request the
password each time the system is booted. This would prevent unauthorized
use of the system. See “Security Option” in the “Advanced BIOS Features”
section for more details.
