# 6 Embedded Functions All embedded board functions on ADLINK’s Computer on Modules are supported at the operating system level using the ADLINK Intelligent Device Interface (AIDI) library. The AIDI API programming interface is compatible and identical across all ADLINK Computer on Modules and all supported operating systems. The AIDI library includes a demo program to demonstrate the library’s functionallity. # 6.1 Watchdog Timer The Express-NR implements a Watchdog timer that can be used to automatically detect software execution problems or system hangs and reset the board if necessary. The Watchdog timer consists of a counter that counts down from an initial value to zero. When the system is operating normally, the software that sets the intial value periodically resets the counter so that the it never reaches zero. If the counter reaches zero before the software resets it, the system is presumed to be malfunctioning and a reset signal is asserted. ![Cartoon illustration of a bulldog wearing a red collar (no text or symbols)](.express-nr-50-1j016-1010-201-en/cb3267c610324f5c2efdc3a09deb443843afabe885695c5976608b6b29d9551e.jpg) The AIDI Library Watchdog functions support Watchdog control of the board. If the Watchdog begins countdown and reaches zero, it will access the CPU's RESET signal to reset the system. This application must call another function named AidiWDogTrigger that triggers the Watchdog to restart to prevent system reset. # AIDI Demo Program - Watchdog Tab The AIDI Demo Program allows retrieval of the current Watchdog status and updating of the Watchdog settings If the Watchdog is enabled, the user can click the WDT Trigger button to manually reset the counter and prevent the system from resetting ![AIDI DEMO Program\nBoard Info StorageArea I2C-Buses HW-Monitor GPIO WatchDog\nWatchDog Info\nNumber: 1 MinTimeout: 0 ms MaxTimeout: 255000 ms\nMinDelay: 0 ms MaxDelay: 255000 ms\nWatchDog Operation\nStart WatchDog\nTimeout(dec): ms\nDelay(dec): ms\nEnable Disable\nGet WatchDog Config\nTimeout(dec): ms\nDelay(dec): ms\nGetConfig\nWDT Trigger\nNote: the sum of timeout value and delay value can't exceed MaxTimeout or MaxDelay](.express-nr-50-1j016-1010-201-en/c0b7820aebc4e153bc949366b8b3c5f6130292f3f3c22df9648942b871636a53.jpg) # 6.2 GPIO GPIO library support is limited to GPIO signals that originate from the Computer on Module and extended to the carrier board. COM Express modules support 4 GPO and 4 GPI signals. Some of ADLINK’s COM Express boards can configure all 8 ports for GPI or GPO use. GPIO signals can be monitored and controlled by using the ADLINK Intelligent Device Interface (AIDI) library that is compatible and identical across all ADLINK COM Express modules and all supported operating systems. The COM Express type II standard assigns the following pins for either GPI or GPO

Pin	Signal Type #	AIDI ID (bit)	Remark
A54	GPIO	0	Express-NR can configure this pin for GPI and GPO

# AIDI Demo Program - GPIO Tab The AIDI Demo Program displays current GPI or GPO status and allows reading of GPI and writing to GPO. The table above links logical port numbers in AIDI to physical port numbers on the COM Express board-to-board connector.

The AIDI Library provides simple APIs at the application level to support these functions and adds alarm functions when voltage or temperature levels exceeds the upper or lower limit set by the user. On the Express-NR the following monitored values can be read from the module: CPU temperature, system temperature, Vcore, 1.8V, 5V, 3.3V and 12V. # AIDI Demo Program # - HW Monitor Tab Field 1 displays detected sensors (number).

# Max CPUID Value Limit When the computer is boots, the operating system executes its CPUID instruction to identify the processor and its capabilities. Before it can do so, it must first query the processor to find out the highest input value the CPUID recognizes. This determines the kind of basic information CPUID can provide the operating system. This option allows you to circumvent problems with older operating systems. When Enabled, the processor will limit the maximum CPUID input value to 03h when queried, even if the processor supports a higher CPUID input value. When Disabled, the processor will return the actual maximum CPUID input value of the processor when queried. # Execute Disable Bit This is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. It allows the processor to classify areas in memory where application code can or cannot execute. When a malicious worm attempts to insert code in the buffer, the processor disables its code execution, preventing damage and worm propagation. To use Execute Disable Bit you must have a PC or server with a processor with Execute Disable Bit capability and a supporting operating system. # Core Multi-Processing This item is visible depending on the CPU being used on the board. Multi-core capability of the CPU is enabled/disabled by this setting if the CPU supports this feature. # Vanderpool Technology This is used to enable or disable the Intel Virtualization Technology (IVT) extension, which is also known by the development code name Vanderpool.

# Boots Graphic Adapter Priority Select which graphics controller to use as the primary boot display device. IGD=Integrated Graphic device. PEG/PCI means external PCI/express graphic device. # Internal Graphics Mode Select Select amount of system memory which used by internal graphics device. # DVMT Mode Select Unified Memory Architecture (UMA) is a concept whereby system memory is shared by both CPU and graphics processor. While this reduces cost, it also reduces the system's performance by taking up a large portion of memory for the graphics processor. Intel's Dynamic Video Memory Technology (DVMT) takes that concept further by allowing the system to dynamically allocate memory resources according to the demands of the system at any point in time. The key idea in DVMT is to improve the efficiency of the memory allocated to either system or graphics processor. When set to Fixed Mode, the graphics driver will reserve a fixed portion of the system memory as graphics memory. When set to DVMT Mode, the graphics chip will dynamically allocate system memory as graphics memory, according to system and graphics requirements. When set to Combo Mode, the graphics driver will allocate a fixed amount of memory as dedicated graphics memory, as well as allow more system memory to be dynamically allocated between the graphics processor and the operating system. # DVMT/FIXED Memory Set the amount of memory according to DVMT Mode Select. # Boot Display Device Select which display interface you want to make it active. # Flat Panel Type Once LVDS is selected from Boot Display Device, this option opens some resolution settings for correct timing out to LVDS interface you want to use. # 8.3.4 IDE Configuration # IDE Configuration Settings You can use this screen to select options for the IDE Configuration Settings.

The checkpoints defined in this document are inherent to the AMIBIOS generic core, and do not include any chipset or board specific checkpoint definitions. # Checkpoints and Beep Codes Definition A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints throughout bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints are very useful for debugging problems that occur during the preboot process. Beep codes are used by the BIOS to indicate a serious or fatal error. They are used when an error occurs before the system video has been initialized, and generated by the system board speaker. # Viewing BIOS Checkpoints Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a “POST Card” or “POST Diagnostic Card”. These are ISA or PCI add-in cards that show the value of I/O port 80h on a LED display. Some computers display checkpoints in the bottom right corner of the screen during POST. This display method is limited, since it only displays checkpoints that occur after the video card has been activated. Keep in mind that not all computers using AMIBIOS enable this feature. In most cases, a checkpoint card is the best tool for viewing AMIBIOS checkpoints. ![American\nMegatrends\nwww.ami.com\nAMIBIOS (C) 2001 American Megatrends, Inc.\nBIOS Date: 10/01/01 12:39:39 Ver: 08.00.03\nPentium (R) III Processor, 933MHz\nPress DEL to run Setup\nChecking NURAM..\nCheckpoint Display\nEVALUATION COPY, NOT FOR SALE\n(C) American Megatrends Inc.,\n63-0100-000001-00101111-100101-015-0AAXT004-Y2KC\n6B3B](.express-nr-50-1j016-1010-201-en/95748642002a7a0e0c714b9141d006a42908394f025ca7dbc241477c17ef8d5f.jpg) # 9.1 Bootblock Initialization Code Checkpoints The Bootblock initialization code sets up the chipset, memory and other components before system memory is available.

The error associated with this value may be different from one platform to the next. # 9.5 DIM Code Checkpoints The Device Initialization Manager (DIM) gets control at various times during BIOS POST to initialize different system busses. The following table describes the main checkpoints where the DIM module is accessed: ![The image displays an icon of a white document with faint horizontal lines and a large red checkmark overlaid on the upper left side. Below the document graphic, the word 'NOTE:' is written in bold, black capital letters.](.express-nr-50-1j016-1010-201-en/5eface5fb601467b2d60f3f66a2af7a3f96e1cfa15cacf92e764a1e7173fcf61.jpg) Checkpoints may differ between different platforms based on system configuration. Checkpoints may change due to vendor requirements, system chipset or option ROMs from add-in PCI devices.

Checkpoint	Description
2A	Initialize different buses and perform the following functions: Reset, Detect, and Disable (function 0); Static Device Initialization (function 1); Boot Output Device Initialization (function 2). Function 0 disables all device nodes, PCI devices, and PnP ISA cards. It also assigns PCI bus numbers. Function 1 initializes all static devices that include manual configured onboard peripherals, memory and I/O decode windows in PCI- PCI bridges, and noncompliant PCI devices. Static resources are also reserved. Function 2 searches for and initializes any PnP, PCI, or AGP video devices.
38	Initialize different buses and perform the following functions: Boot Input Device Initialization (function 3); IPL Device Initialization (function 4); General Device Initialization (function 5). Function 3 searches for and configures PCI input devices and detects if system has standard keyboard controller. Function 4 searches for and configures all PnP and PCI boot devices. Function 5 configures all onboard peripherals that are set to an automatic configuration and configures all remaining PnP and PCI devices.

While control is in the different functions, additional checkpoints are output to port 80h as a word value to identify the routines under execution. The low byte value indicates the main POST Code Checkpoint. The high byte is divided into two nibbles and contains two fields. The details of the high byte of these checkpoints are as follows: # HIGH BYTE XY The upper nibble ‘X’ indicates the function number that is being executed. ‘X’ can be from 0 to 7. 0 = func#0, disable all devices on the BUS concerned. 1 = func#1, static devices initialization on the BUS concerned. 2 = func#2, output device initialization on the BUS concerned. 3 = func#3, input device initialization on the BUS concerned. 4 = func#4, IPL device initialization on the BUS concerned. 5 = func#5, general device initialization on the BUS concerned. 6 = func#6, error reporting for the BUS concerned. 7 = func#7, add-on ROM initialization for all BUSes. 8 = func#8, BBS ROM initialization for all BUSes. The lower nibble ‘Y’ indicates the BUS on which the different routines are being executed. ‘Y’ can be from 0 to 5. 0 = Generic DIM (Device Initialization Manager). 1 = Onboard System devices. 2 = ISA devices. 3 = EISA devices. 4 = ISA PnP devices. 5 = PCI devices. # 9.6 ACPI Runtime Checkpoints ACPI checkpoints are displayed when an ACPI capable operating system either enters or leaves a sleep state. The following table describes the type of checkpoints that may occur during ACPI sleep or wake events: ![The image displays an icon featuring a white document with a folded top-right corner.
