1- Getting Started

1.1 - Introduction

The UEFI BIOS is a small program which runs when your computer starts and configures its basic functions. That configuration is automatic, and most users will be satisfied with the default configuration. If the default configuration is not sufficient, the BIOS has setup menus which can be used to reconfigure the computer.

The purpose of this manual is to document the function of the BIOS and its available configuration options. The text of this document lists the BIOS menus and options exactly as they appear in the BIOS menus: in the correct order, with the correct default values for this BIOS version. Some options are hidden based on how other options are set and which hardware is detected in the system, so some options may not appear on all systems. Informative screenshots are also provided throughout, but their contents may not exactly match this BIOS version.

1.2 - First Time of Accessing the Setup Menu

To access the BIOS setup menu, hold the DEL key on the keyboard while turning on the system. After a few seconds, the BIOS front page menu is shown. Passwords must be set to proceed. To enhance the security of your system, create a password that is at least 8 characters long. Ensure it includes lowercase letters, uppercase letters, and special symbols.

• The privilege of User Password is equal to Supervisor Password in the BIOS setup menu.

• User Password is optional. Leave it empty if you don't want it.

• The Supervisor Password is required to activate the factory reset button function to prevent unauthorized resets triggered by the Factory Reset Button. The behavior is described in the “” section.

To access the BIOS setup menu, hold the DEL key on the keyboard while turning on the system. After a few seconds, the BIOS front page menu is shown:

On each menu, the selected option is shown in white, other options are shown in blue, and read-only options are shown in gray. Some menus have multiple screens, which are shown at the top of the screen. The active screen is shown with a gray background and inactive screens are shown with blue backgrounds.

BIOS menus are navigated by pressing keys on the keyboard:

• F1 shows help on available keyboard shortcuts

• ↑/↓ arrow keys select the option above or below the currently-selected option

• →/← arrow keys activate the screen to the right or left of the currently-activated screen

• Enter activates the selected option. If that option is a menu, it is opened. If it is a configuration option, a dialog is opened to select a new value.

To access the BIOS boot manager, hold the F10 key on the keyboard while turning on the system. After a few seconds, the BIOS boot manager is shown:

To access the Secure Boot Menu, hold the Ctrl+Alt+F4 key on the keyboard while turning on the system. After a few seconds, the Secure Boot menu is shown:

• The system will prompt you to set admin passwords to configure secure boot for the first time.

• Enter the admin password to access the secure boot setting page.

The Error LED is effectively controlled by BIOS based on the following conditions:

Blinking frequencies:

• Slow blinking: 0.5 Hz (Blinks once every two seconds)

• Medium blinking: 1 Hz (Blinks once every second)

• Fast blinking: 4 Hz (Blinks four times every second)

When RTC battery is low, BIOS will display "Warning: Low RTC battery. Press any key to continue." for 30 seconds during the BIOS POST.

If a BIOS update gets interrupted, your system might fail to boot (it could auto-shutdown, continuous reboots, and prevent access the BIOS menu). The system will attempt to recover the BIOS image from backup. During this process, the screen will stay black and the Error LED will stay solid on to show crisis recovery is running. Once completed, the recovery process will revert the system BIOS to the mass production version.

1. Turn off the system completely.

2. Press and hold the Factory Reset button.

3. While still holding Reset, press the Power button to turn the system on.

4. Wait 5 seconds after the system powers up, then release the Factory Reset button.

The Result:

• All BIOS settings return to default.

• Admin passwords are deleted.

You can disable the Factory Reset Button under Onlogic Feature Configuration of the BIOS setup menu.

SSD S.M.A.R.T Health Check is enabled by default in the Onlogic Feature Configuration.

BIOS will check the SSD health status and display warnings if the status is bad for 30 seconds.

• Normal Operation: Once the computer boots to an OS, the BIOS constantly resets a hidden countdown timer to prove the system is still running smoothly.

• If the system freezes ("hangs") and stops working, it fails to reset that timer.

• When the timer runs out (hits zero), it automatically forces the computer to restart to recover from the freeze.

To enable In-Band ECC in the memory configuration page, Intel Trusted Execution Technology must be disabled in the CPU configuration page.

Several options are available on the Main page:

• Platform information: a comprehensive summary of the computer's hardware components and firmware details

• Language: Select which language to display

• System Time

• System Date

The Advanced menu contains the following options:

• BT

  • Enable/Disable BT module

• TPM Active PCR Hash Algorithm (read-only)

• TPM Hardware Supported Hash Algorithm (read-only)

• BIOS Supported Hash Algorithm (read-only)

The Power menu contains the following options:

• Wake on RTC from S5

  • Auto wake on S5, By Day of Month or Fixed time of every day

• Restore AC Power Loss

  • Select Power Off/ Power On/ Last State after power loss restore

The Boot menu contains the following options:

• Network Stack

  • Network Stack Support: Windows 8 BitLocker Unlock, UEFI IPv4/IPv6 PXE, Legacy PXE OPROM

• PXE Boot capability

  • Disabled : Support Network Stack

The exit screen provides options to leave the setup utility and to load and save settings.

• Exit Saving Changes: saves the current configuration and restarts the system to apply it

• Save Change Without Exit: saves the current configuration but does not restart the system

• Exit Discarding Changes: returns to the front page without saving or applying the current configuration

• Load Optimal Defaults: loads the factory default configuration

BIOS Updates

Make sure your system’s drivers are installed and up-to-date.

This model uses the new Intel GPY115/EC1000S Ethernet controller provided by the Elkhart Lake platform. Some operating systems are not compatible, or require additional setup by the user for this Ethernet controller. *For systems purchased before March 1st 2023, Ubuntu can be installed after the Ethernet firmware has been updated. Customers interested in this can contact OnLogic Tech Support to RMA the system for this update.

The Helix 300 and 310 systems offer optional CAN bus and isolated Digital IO support. This functionality is through the processor’s supporting ARM microcontroller, known as the Programmable Services Engine (PSE).

The PSE is isolated from the core processor, runs its own OS (), but can be sent messages over the system’s Host Embedded Controller Interface (or HECI). The OS is transparent to the user. This interface may be used to send and receive CAN messages alongside setting and reading the Digital IO.

Requirements: An HX300 or HX310 with Windows and the latest HECI driver. The HECI Windows driver is provided and supported by Intel, and will be preinstalled on HX300 units purchased with Windows. If Windows is installed by the user, the driver is included with our driver package linked at the top of this page.

1. Download the HX300’s .

2. Open a command window, and navigate to the location of the downloaded file.

   1. Press the Windows Key + R

   2. Type cmd.exe and hit Enter

The (optional) MOD110 digital input/output (DIO) expansion adds up to eight digital inputs and outputs to the system, and an additional CAN port. It also optionally provides support for pulse width modulation (PWM) on three of the eight digital output pins, and support for using a quadrature encoder peripheral (QEP) in place of the first and/or second group of three digital inputs.

See our dedicated DIO article on how to get started with the . The HX300 series utilizes the MOD106 DIO, however the PSE controls are the same for both parts and both are opto-isolated modules so this guide can be used for both.

The HECI interface uses packed structures to send data between the host and PSE. Specific type structures are provided in the sample code, but an outline of the message format is available below:

Input Impedance

Each digital input has a 10K internal pullup and a 10K series resistor.

The TM260 (the HX330 with ThinManager Ready firmware) is compatible with ThinManager 11 or higher. Customers interested in the ThinManager WiFi Boot option should use ThinManager 13.2 to enable this feature. Checkout our with more info about ThinManager WiFi Boot.

The TM260 requires version 14 of the Terminal Capability Database (TermCap) in order to properly download the firmware it needs to function. Customers can follow this to perform this update for their systems.

As with other newer model systems, this model includes a firmware TPM by default. It functions similarly to a TPM 2.0 module. If the optional dedicated TPM 2.0 module is added to the system, the firmware TPM will need to be disabled to allow it to function.

The firmware TPM can be disabled in the BIOS:

1. Power on the system and press Del to enter the Front Page menu.

2. Select Setup Utility.

3. Navigate to the Advanced tab and open Chipset Configuration.

4. Disable Platform Trust Technology.

The dedicated TPM should now be functional and detectable in TPM.MSC or Device Manager.

If your unit fails to boot or power on, a CMOS reset may help. You will need to open the unit to perform the reset. This does not void your warranty, however, any damage caused by doing so will not be covered. Ensure your body is discharged of any static electricity by touching a grounded metal surface.

The mainboard power is applied to the HX320 platform through a 3-pin terminal block connector (Mating part: Dinkle 2ESSM-03P or equivalent).

The system is operational from 12V~36V. The maximum rated current of the connector is 15A per pin. Use a wire gauge that is rated for the operational current. Cables should be properly terminated with wire ferrules. Do not use the terminal block with tinned wire ends or solid core wire. See below for the connector pinout which is also indicated on the terminal block mounting panel adjacent to the connector. Installation of DC connection shall only be performed by skilled personnel and in accordance with your local and national electrical code (Example: NEC, CEC).

When using the remote switch connections with the terminal block option, mating power switch cables should be a twisted-pair wire with floating shield to assure proper immunity to EMI/RFI. It is recommended to keep wires at less than 3 meters in length. Switches should be momentary contact type only.

The RTC battery on the HX320 platform is used to maintain the real-time clock for the system. If the RTC battery is low, the Error LED will indicate the error event. The cabled RTC battery should be replaced with an UL listed battery. The battery shall use a ACES 50276-002H or equivalent connector to mate with the on-board connector.

Two Intel Twin Lake Processor options are available for the HX320.

The HX320 platform has the onboard LPDDR5 chips:

• Capacity: 8GB / 16GB

• Speed: 4800 MT/s

The power consumption of the HX320 system was measured for various system configurations, workloads, and power states at 12V system input voltages. Tests were performed using BurnInTest v10.2 to stress system components. The build configurations and power consumption are listed in the tables below.

*The configurations below are using representative samples of internal devices, the specific components mentioned below may vary from the devices provided by OnLogic. The power consumption for each system configuration is record below

Configuration 1 : N250

Configuration 2 : N355

These DC levels specified are the absolute max values for the pins for function and safety of the system. The protection circuitry allows for brief transient voltages above these levels without the system turning off or being damaged. A transient voltage suppressor on the power input allows momentary excursions above stated limits. For input power consumption and current see Power Consumption

The platform supports multiple power states. The wake-up events can be configured in the BIOS. This section describes the supported power management functions and gives information on protection circuitry for power adapters. Low power shutdown is an additional option in the BIOS. See for more information.
