MicroPCI Daughter Card Installation
The IB755 embedded board is integrated with a MicroPCI socket that
uses SO-DIMM 144-pin connectors. These sockets can accommodate the
optional MicroPCI daughter cards.
To insert the MicroPCI daughter cards, position it at 30° to the PCB and
gently push it into the MicroPCI connector (See Figure 1 below). The
card will not fit when inserted at an angle of 45° or 15°. Once inserted,
slowly press the card towards the PCB until it locks on both sides to the
clips of the connector. Screw the card to the PCB to secure the
installation. To remove the MicroPCI card, pull the ‘clips’ sideways as
shown in Figure 2 below.

BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your system’s
ROM provides critical low-level support for standard devices such as
disk drives, parallel port and serial ports. It also adds virus and password
protection, as well as special support for detailed fine-tuning of the
chipset controlling the entire system.
BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the key immediately allows you to
enter the Setup utility. If you are a little bit late pressing the key,
POST (Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the , and keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:
Press to Enter Setup
In general, you press the arrow keys to highlight items, to select,
the and keys to change entries, for help and
to quit.
When you enter the Setup utility, the Main Menu screen will appear on the
screen. The Main Menu allows you to select from various setup functions
and exit choices.

IRQ Wakeup Events
The VGA, LPT & COM, HDD & FDD, and PCI master are I/O events
which can prevent the system from entering a power saving mode or can
awaken the system from such a mode. When an I/O device wants to gain
the attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
