4.1 Introduction
The BIOS is programmed onto the BIOS chip. The BIOS setup program allows changes to
certain system settings. This chapter outlines the options that can be changed.
4.1.1 Starting Setup
The UEFI BIOS is activated when the computer is turned on. The setup program can be
activated in one of two ways.
1. Press the DEL or F2 key as soon as the system is turned on or
2. Press the DEL or F2 key when the “Press DEL or F2 to enter SETUP”
message appears on the screen. 0.
If the message disappears before the DEL or F2 key is pressed, restart the computer and
try again.
4.1.2 Using Setup
Use the arrow keys to highlight items, press ENTER to select, use the PageUp and
PageDown keys to change entries, press F1 for help and press E

IDS-H61 Digital Signage Player
WARNING:
Take Anti-Static precautions whenever maintenance is being carried out on the
system components. Failure to take anti-static precautions can cause
permanent system damage. For more details on anti-static precautions, please
refer to Section
82.2.1.
5.1 System Maintenance Overview
NOTE:
When doing maintenance operations on the system, please follow the
instructions in this chapter. Failure to follow these instructions may lead to
personal injury and system damage.
To preserve the working integrity of the IDS-H61, the system must be properly maintained.
If internal components need replacement, the proper maintenance procedures must be
followed to ensure the system can continue to operate normally.
5.2 Component Replacement Procedure
WARNING!
Users are not advised to attempt to repair or replace any internal or
external components of the IDS-H61 embedded system other than
those listed below. If any other components fail or need replacement,
contact the IEI reseller or vendor you purchased the IDS-H61 from or
contact an IEI sales representative directly. To contact an IEI sales
representative, please send an email to
The system components listed below can all be replaced if they fail:

82..5.2.1)
5.2.1 mSATA Replacement
The IDS-H61 is preinstalled with one mSATA module. To replace the mSATA module,
please refer to the diagram and instructions below.
Step 1: Remove the top cover by removing the four retention screws on both side panels
(two on each side). See
Figure 5-1.
Figure 5-1: System Cover Retention Screws
Step 2: Locate the mSATA module installed on the motherboard (
Figure 5-2: mSATA Module Location
Figure 5-2).
Page 42
IDS-H61 Digital Signage Player
Step 3: Remove the mSATA module. Push the two spring clips in to release the
mSATA module.
Step 4: Insert a new mSATA module into the socket at an angle. Line up the notch
on the card with the notch on the connector. Slide the mSATA module into the
socket at an angle of about 20º (
Figure 5-3: mSATA Module Installation
Step 5: Push down until the card clips into place. Push the other end of the card
down until it clips into place on the plastic connector.Step 0:
Figure 5-3).
5.2.2 SO-DIMM Replacement
WARNING:
Using incorrectly specified SO-DIMM may cause permanently damage
the IDS-H61. Please make sure the purchased SO-DIMM complies
with the memory specifications of the IDS-H61.
To replace a SO-DIMM memory module into a SO-DIMM socket, please follow the steps
below.

Step 1: Remove the top cover by removing the four retention screws on both side panels
(two on each side). See
Step 2: Locate the SO-DIMM. (

83Figure 5-4).
Figure 5-4: SO-DIMM Removal
Step 3: Remove the SO-DIMM by releasing the arms on the SO-DIMM socket. Align the
new SO-DIMM with the socket. The SO-DIMM must be oriented in such a way
that the notch in the middle of the SO-DIMM must be aligned with the plastic
bridge in the socket (
83Figure 5-5).
Step 4: Insert the SO-DIMM. Push the SO-DIMM chip into the socket at an angle
83Figure 5-5).

C Watchdog Timer
Page 60
IDS-H61 Digital Signage Player
NOTE:
The following discussion applies to DOS environment. IEI support is
contacted or the IEI website visited for specific drivers for more
sophisticated operating systems, e.g., Windows and Linux.
The Watchdog Timer is provided to ensure that standalone systems can always recover
from catastrophic conditions that cause the CPU to crash. This condition may have
occurred by external EMI or a software bug. When the CPU stops working correctly,
Watchdog Timer either performs a hardware reset (cold boot) or a Non-Maskable Interrupt
(NMI) to bring the system back to a known state.
A BIOS function call (INT 15H) is used to control the Watchdog Timer:
INT 15H:
AH – 6FH Sub-function:
AL – 2: Sets the Watchdog Timer’s period.
BL: Time-out value (Its unit-second is dependent on the item “Watchdog
Timer unit select” in CMOS setup).
Table C-1: AH-6FH Sub-function
Call sub-function 2 to set the time-out period of Watchdog Timer first. If the time-out value
is not zero, the Watchdog Timer starts counting down. While the timer value reaches zero,
the system resets. To ensure that this reset condition does not occur, calling sub-function
2 must periodically refresh the Watchdog Timer. However, the Watchdog timer is disabled
if the time-out value is set to zero.
A tolerance of at least 10% must be maintained to avoid unknown routines within the
operating system (DOS), such as disk I/O that can be very time-consuming.
Page 61
NOTE:
When exiting a program it is necessary to disable the Watchdog Timer,
otherwise the system resets.
