Frequently Asked Questions (FAQ) - Stone Computers

BOAMOT-489 - Asus PRIME Q270M-C is part of the Asus commercial range, for which Asus have opted to use the traditional text based menu system instead of the 'consumer' orinetated GUI..

Duote are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

To access the motherboard's built in EZFlash BIOS update utility, you need to press ALT + F2 during POST.

Note: If you have trouble accessing the EZFlash utility, try the following steps:

• Make sure you dont use a KVM switcher or USB hub in between the USB keyboard and the system.
• You can hold down ALT + F2 as soon as the keyboard has initialised (i.e. the numlock light blinks), until you see EZFlash appear.
• As a last resort, use a PS/2 keyboard, although this should be unnecessary.

• While the utility has the monochrome UI used in past generations, it operates in the same way as any of the other Asus motherboards which use the GUI.

Putting the Display Panel of your Stone All in One PC into Sleep

The chassis design of the Stone All in One does not incorporate an independent power button to control the power state of the display panel. The panel is normally fully active when the machine is awake.

Customers wishing for the ability to manually control the screen power state could use the attached alternative software based method of putting the display to sleep.

Setup

• Download the attached file 'Display off x86.zip' or 'Display off x64.zip' depending on the architecture of your operating system.
• Extract the folder contained within the downloaded .zip file to the root of C: drive.
  
• Inside the 'Display off' folder there is a shortcut file named 'Turn Off Display', copy this to the desktop or your desired location.
  
• Doubling clicking 'Turn Off Display' will initiate the command and after a short pause the display will turn off, the display can be turned on again via user input from the mouse or keyboard.
• Finally, you have the option to set a shortcut keystroke to initiate the 'Turn Off Display' command: to do this open the properties of the 'Turn Off Display' short cut file and define your desired key combination in the field marked below.

Applies to:

• Stone desktop and All-In-One products using 7-series and 8-series Intel motherboards

Clearing the CMOS

The method used to clear the CMOS settings on an Intel Desktop motherboard is different to the method used on Asus or MSI motherboards. Use the instructions below to clear the settings.

Intel Desktop Board CMOS Clear Instructions

Method 1

• Shut the system down.
• Find the BIOS Configuration Jumper (this may be marked, CONFIG, RECOVERY, or BIOS depending on model, see below for an example).
• Put the configuration jumper from the pins 1-2 normal position to the pins 2-3 configure position.
• Turn the system on.
• The BIOS setup menu will automatically appear if the system is functional.
• Use F9 to request CMOS defaults or use the Save/Exit menu to load defaults, and then save them.
• Shut the system down.
• Put the configuration jumper from the pins 2-3 configure position to the pins 1-2 normal position.

Location of the Recovery Jumper on the Intel DQ77MK

Configuration Jumper Summary

Jumper Position Mode Function 1-2 Normal Normal operation. 2-3 Configure Forces entry into BIOS setup; also may reveal additional BIOS setup options. Use this mode to request CMOS defaults. Remove Recovery Use this mode to attempt to reflash the system, perhaps because of a failed BIOS updated or an incompatible processor that requires a BIOS updated to function properly. Remember: Turning the system on with the configuration jumper completely removed will put the system into BIOS recovery mode. In this mode, the system will attempt to reflash the BIOS from media such as a FAT32 formatted USB pen drive or a CDROM drive.

Method 2

• Shut the system down.
• Disconnect the AC Mains.
• Remove the CMOS Battery from the CMOS.
• Short the battery terminals on the motherboard together using a screwdriver or other metal object for at least 10 seconds.
• Refit the battery.
• Reconnect the AC Mains.

Applies to:

• Intel Desktop Motherboards

Clearing the CMOS

The method used to clear the CMOS settings on a Stone / MSI H61M motherboard is different to the method used on the Intel desktop board range. Use the instructions below to clear the settings.

MSI CMOS Clear Instructions

• Ensure the system is switched off
• Short the JBAT1 2-pin jumper block for 10 seconds either using a jumper, or a screwdriver
• Remove the short
• Turn the system back on

Note: Do not short the JBAT1 terminal while the system is powered on.

Use a suitable screwdriver or a 2-pin jumper to short JBAT1.

Applies to:

• Stone / MSI H61M desktop boards
  • BOAMOT-438 - SC Micro ATX H61M-P31 LGA , DDR3 x2, DVI, VGA, PCIE x16, SATA II x4, DX10.1.
  • BOAMOT-443 - SC Micro ATX H61M-P31/W8 LGA , DDR3 x2, DVI, VGA, PCIE x16, SATA II x4, DX10.1.

Wake On LAN

Wake on LAN from S5 (power-off) state on systems that include an Intel LAN / Ethernet Controller may require operating system configuration so that the system wakes up when a magic packet is sent to the adapter.

1. Install LAN driver:

Install the latest tested driver from the Stone Driver Finder or the motherboard manufacturer's web site.

IMPORTANT: Please ensure that you install the full driver package, not just the base driver. The base driver does not give you access to additional features installed by the full package.

2. Check LAN controller settings:

Enable the following setting in the LAN controller’s properties within Windows; ‘Wake on Magic Packet from power off state’ as shown in the image below.

Note: Some laptop models do not support Wake on LAN from S5 while the lid is closed. Please test the required functionality in your development environment.

Windows 10 Considerations

In addition to Windows 10 requiring that fast start-up is turned off in order to support WOL, please note that some Intel LAN controllers do not have an official Windows 10 driver available from Intel. Some controllers such as the L are only supported by the Windows 10 "inbox" driver. Most of these inbox drivers do not support WOL functionality. This means that a system that has an L and supported WOL on Windows 7 or Windows 8.x may not support WOL on Windows 10.

Applies to:

• Desktop and selected laptop systems that include an Intel LAN controller

Stone Computers systems USB 3.0 ports can be recognised by the blue colour of the USB port connector. This is an industry standard. Use the USB 3.0 ports to take advantage of much faster data transfer rates compared to USB 2.0, when used with devices that support this standard.

Note: USB 3.0 ports are backwards compatible with USB 2.0 devices, and vice-versa. To get the best performance from your devices, always plug USB 3.0 capable peripherals into USB 3.0 ports.

Applies to:

• All Stone PCs and laptops from that include USB 3.0 controllers (6 Series chipsets and later).

The Serial Number

When logging a support call with Stone Computers Service helpdesk, one of the details that we need to identify the machine is the Serial number.

This is usually found on a silver Stone sticker (underneath the bar code) on the case. For any reason this number has become faded over time due to use, you are able to access it through the command line as below.

How to Retrieve the Serial Number from the Motherboard

These steps are designed for a system administrator, or for customers which have local administrator rights. If you do not have the permissions to add programs or make changes to your system, you may need your administrator to carry out these instructions for you:

Steps:

• Open an Administrative Command prompt
• Type wmic bios get serialnumber and then press Enter

This will then query the bios for the system serial number and return it in the command line.

Tip: Alternatively, use the Stone WMI tool to get the serial number as well as other additional BIOS information, including BIOS version and UUID.

Applies to:

• Stone branded Desktop and Laptop systems

Most Stone PCs come equiped with a range of output ports, depending on model.

The 15-pin VGA port is slowly being replaced in favour of more modern alternatives, such as DVI, Display Port, and HDMI. If your Stone system includesa Blue DVI port (DVI-I), then this can be adapted to provide an 15-pin VGA port using the DVI to VGA adapter included in your manual pack.

Systems that include a white DVI port only (DVI-D) usually cannot be adapted to provide a 15-pin VGA output.

Note: The Intel DQ67SW and DQ77MK are example motherboards that do not include the 15-pin VGA port but do however include the Blue DVI port which can have the adapter fitted.

Applies to:

• All Stone desktop products fitted with an analogue capable DVI port (DVI-I)

Clearing the AMT Configuration or Settings

Intel Q Series desktop motherboards contain AMT functionality. AMT functionality and settings are not cleared by resetting the main CMOS by loading BIOS defaults. Intel B series boards can also have AMT functionality and again the AMT settings are not cleared by resetting the main CMOS by loading BIOS defaults.

To clear the AMT settings, either perform a full manual settings clear or using the dedicated MEBX (Management Engine BIOS Extension) Reset Jumper.

Using the MEBX Reset Jumper (the recommended method)

• Locate the MEBX Reset Header (see diagrams below).
• Shut the system down and disconnect the AC mains.
• Short pins 1 and 2 of the header together for 5 seconds.
• Reconnect the AC mains.
• Test that the password has been cleared.

Note: Do not leave the AC mains connected whilst shorting the MEBX reset header. Do not have the system switched on whilst shorting the MEBX header as you may damage the motherboard.

Main Full Settings Clear (alternative method)

• Disconnect the AC mains.
• Remove the CMOS battery.
• Short the battery terminals on the motherboard together for at least 10 seconds.
• Reinstall the CMOS battery, observing the correct polarity.
• Reconnect the AC mains.
• Test the system.

After clearing the settings using either method, the AMT default password of admin should be restored.

Applies to:

• Intel Q67 Series desktop motherboards (DQ67SW, DQ67OW, DQ67EP)
• Intel Q77 Series desktop motherboards (DQ77MK, DQ77CP, DQ77KB)
• Intel B75 Series desktop motherboard (DB75EN)

If your Stone Computers system uses an Intel DQ77MK Desktop board, you will find that it is equipped with two gigabit LAN ports. We recommend that customers use the RED LAN port to take advantage of management features and for the most efficent operation. However either port will be adequate for all day to day use on your network.

Network Card Models

Red Network Port: Management and Data - Intel LM (PCI ID: PCI\VEN_&DEV_)

All current Stone PC systems (with exception of some netbook and tablet products) are 64-bit Windows capable. 64-bit capable systems allow a 64-bit version of Windows to address more memory, whereas traditional 32-bit systems were limited to 4GB of memory. If your system has more than 4GB of memory you will need to be running 64-bit Windows to take advantage of this increased capacity.

Note: Intel Atom based desktop products (as well as Atom based netbooks) are also only suported under 32-bit Windows, meaning that they cannot make use of more then 4GB of system memory.

Applies to:

• All desktop, laptop, netbook and tablet products. 

We recommend you use the standard 32-bit version of Internet Explorer for the best experience.

• For most purposes the standard (32-bit) version of Internet Explorer will perform perfectly.
• While the 64-bit version of Internet Explorer can potentially use more system memory, you may find that some web page add-ons do not load or install using 64-bit Internet Explorer.

 Applies to:

• Desktop and Laptop Products
• Microsoft Windows
• Internet Explorer

USB Wake from Sleep

By default, systems that include the MSI H81M-P33 motherboard and were produced before 16/1/ will not wake from sleep using a USB or PS/2 keyboard or mouse. To wake the system from the S3 Sleep State (STR), you need to use the system's power button.

Systems produced on 16/1/ or later have this functionality enabled in the factory.

If you want to configure the system to wake using USB or PS/2 devices, BIOS settings must be changed and jumpers on the motherboard must be moved.

Tip: If you are a Stone customer and require USB wake functionality to be enabled by default on future systems please talk to your account manager.

Instructions

Motherboard Jumpers

• Shut down the PC and disconnect the AC mains
• Remove the PC lid
• Locate the JUSB_PW1 and JUSB_PW2 jumpers.

• Move the jumpers from the "disabled" position (pins 1-2) to the "enabled" position (pins 2-3) on JUSB_PW1 and JUSB_PW2.

• This means that JUSB_PW1 (behind the CPU, near the VGA port) jumper should be in the right hand position when looked at from the main ATX power connector side of the board.
• JUSB_PW2 (near the PCI Express x1 slot) jumper should be in the front position, when looked at from the main ATX power connector side of the board.

Note: The instructions above replace those in the motherboard manual which do not correctly show jumpers fitted in the "enabled" position. When you remove the jumper from the "disabled" position you must refit it in the "enabled" position - this is not clear in the motherboard manual.

BIOS Settings

• Reconnect the AC mains and turn on the system.
• Enter the BIOS by using the DEL key immediately from power-on.
• Enter the Settings menu.

• Enter the Advanced menu.

• Then go into the Wake Up Event Setup menu.

• Enable wake on USB and/or PS/2 as required.

• Press F10 to save and exit the BIOS.

Note 1: As of 16/1/, the available BIOS flash file for this motherboard now enables this functionality. This file can be downloaded here or here. The jumpers still need to be configured on systems produced before 16/1/. Note 2: This issue is not related to Wake on LAN (WOL) functionality.

Applies to:

• BOAMOT-464 - Stone / MSI H81M-P33

Scenario

You wish to boot your Windows 8.x (or Windows 10) Stone Desktop PC or All-in-one (AiO) machine using the in-built legacy PXE option firmware so that you may connect to your existing bootable network infrastructure for the purposes of operating system deployment. 

You system has been supplied to you from Stone with Windows 8 or above and when you attempt to to use PXE boot you are unable to find the boot device in the F8 boot menu or in the boot device priority list within the system BIOS. 

Cause

Windows 8.x (and 10) based machines must be shipped from the manufacturer with a BIOS feature called 'Secure Boot' enabled. This feature is intended to ensure that only authorised software can be booted on the host system

When Secure Boot is activated on a PC, the PC checks each piece of software, including the Option ROMs and the operating system, against databases of known-good signatures maintained in the firmware. If each piece of software is valid, the firmware runs the software and the operating system. This restricts the use of the Legacy PXE option ROM.

Resolution

1. Boot the machine into the BIOS by tapping either F2 or DEL immediately after powering it on.
2. Go to the "Boot" section.
3. Go to "Secure boot" sub-menu.​​
4. Change 'OS type' from 'Windows UEFI mode' to 'Other OS'.
5. Exit the BIOS saving the changes
6. After the system restarts the Intel or Realtek (as shown in the image below) network boot agent will now be available in the F8 boot menu and boot priority list within the BIOS.

Note: This will not affect the systems ability to boot a UEFI based operating system installation.

Applies to:

• Stone PCs with Asus motherboards including but not limited to: H81T (BOAMOT-471), B85M-E (BOAMOT-463), CS-B (BOAMOT-467), Q87M-E (BOAMOT-473), H81M-P-SI (BOAMOT-476) and the Q87-T (BOAMOT-470). Asus Skylake based platforms using Intel 6th generation core i processors

Using Bitlocker and TPM 2.0 on Windows 7

TPM is a method of storing the encryption key used by Bitlocker to protect the contents of the Windows drive. Typically the new Skylake platform systems and newer have moved from TPM 1.2 to TPM 2.0. This is natively supported by Windows 10.

If you want to use TPM 2.0 on Windows 7 then this is possible, but only with the following:

• You must use Windows 7 x64. 32-bit / x86 versions of Windows 7 do not support TPM 2.0
• You need to install Windows 7 in UEFI mode. This is a BIOS setting that has to be made before you partition the hard drive or install Windows. Systems installed in UEFI mode will have a GPT partitioned hard disk.
• In addition to enabling UEFI mode, you may need to disable Secure boot in the BIOS setup, to enable Windows 7 booting.
• The Windows 7 hotfix for Microsoft Knowledgebase article must be installed. If you have all of the latest Windows updates, then this should already be included.

Note: You may also need to the latest chipset drivers for your platform installed, especially if the TPM 2.0 functionality is delivered through Intel's Platform Trust Technology (PTT), for example on Skylake systems.

Stonebook Pro and Stonebook Lite

The Skylake Stonebook Pro and Stonebook Lite notebooks support Windows 7 and UEFI mode. This support was added in the 6/9/16 BIOS update. Without this BIOS, the system will not be able to operate in UEFI mode with Windows 7, meaning that TPM functionality will not be available. If you switch from non-UEFI (legacy) to UEFI modes, you may need to remove the partitioning information on the notebooks hard drive to complete your operating system deployment.

Applies to:

• All desktops and notebooks with TPM 2.0 required to run Windows 7

All modern flat panel screens are made up of tiny lit elements known as pixels. These pixels use combinations of red, blue and green light to build images on the screen.

It is a fact of the technology that even despite the highest manufacturing standards, that sometimes it is possible to receive a new screen and have a dead pixel. This could be visible as a pixel that is constantly white, constantly black, or partially stuck - for example, it might be a stuck on as red, blue or green.

Example: The example below shows a dead, or stuck pixel. In this case, the pixel is off, or black.

What Is the Pixel Policy Standard?

Manufacturers make equipment to an international standard (called ISO -2) so that users receive the experience that they expect. Most equipment that Stone supplies is known as Class II equipment as regards pixel policy. Details of what the policy is are covered below. It is only when you have a number of dead pixels over the amount specified in the table is the product deemed to have fallen short of the standard.

ISO -2 Class II Pixel Policy - How Many Faulty Pixels Can there be?

Class White Pixels Black Pixels R/G/B Pixels W/B Clusters R/G/B Clusters II - Per Million Pixels 2 2 5 0 2

• W/B Clusters: How many white or black stuck pixel clusters are permitted: 0.
• R/G/B Clusters: How many Red/Green/Blue semi stuck pixel clusters are allowed: Up to 2.

​These numbers are all per million screen pixels. On a standard 15.6" laptop screen that has a x768 resolution, there are just over one million pixels, so the above numbers apply exactly.

So, am I Covered by Warranty?

Stone is proud to deliver excellent products and customer service, and as such we support our partners and suppliers with this pixel policy. If you receive a product that is outside of this policy please let us know within 30 days so that we can get the unit exchanged under our dead-on-arrival (DOA) facility.

If you have a single black or white stuck pixel, then usually this is not covered. Please do not hesitate to contact our Support team if you are unsure if you are covered or not.

Secure Boot and UEFI Boot

Secure Boot and UEFI boot are two technologies that go hand in hand to enhance the security and capabilities of a modern PC system.

Secure Boot uses a signature to ensure that the operating system loader is trusted. In other words, if the operating system loader is damaged by a malicious attack, such as by a virus or malware, the system can detect this and prevent the system from booting. This gives the system administrator awareness of a problem; the system can be cleaned and then restored to normal service, protecting the users data.

UEFI boot is an alternative to the legacy method of booting an operating system, known as the "BIOS". The way the system firmware interacts with the operating system is different and more flexible. For example, bootable devices greater than 2TB in size are supported. However, the operating system has to be UEFI aware - for example, Windows XP cannot boot if UEFI is enabled in the BIOS - and the disk needs to be partitioned using a newer method known as GPT, as opposed to the older MBR (master boot record) method.

Additionally, you will usually need to reinstall or redeploy a system if you change to UEFI mode after original installation. If you are using Windows images, you may need to build a new image.

Note: Some BIOSes have a UEFI-CSM mode. CSM stands for compatibility support mode. In this mode, UEFI features are enabled, and things such as Secure Boot will still work. However with CSM, the BIOS will detect the boot partition on the bootable media and enable MBR support as required. In this way, it is still possible to use MBR partitioned disks and Windows installations after moving to UEFI mode.

What do I need to get UEFI or Secure Boot Functionality?

Generally, most 7 or 8 series chipset based systems have BIOSes that have been developed with UEFI support and secure boot support in mind.

Some 6 series based systems have a mixture of capabilities:

• H61 based systems: Usually have Secure Boot and UEFI boot capability with a BIOS update. Some manufacturers (i.e. MSI) have release a specific version of the motherboard with Windows 8 - and thus Secure boot and UEFI support.
• H67 / Q67 based systems: Usually have UEFI capability, often available after a BIOS update. Often Secure boot functionality is missing. Customers looking to buy Windows 8 capable systems in either bought H61 (with a BIOS update) or B75/H77/Q77/Z77 motherboards; there was no need for the motherboard manufacturers to make these systems secure boot capable.

Older systems, such as those based on the 4 or 5 series chipsets do not generally have UEFI or secure boot capabilities.

What Mode Should I Be Using?

Windows 8 / Windows 8.1

Generally secure boot should be ENABLED. For secure boot to operate, UEFI boot must also be enabled.

Windows 7

Secure boot is not supported by Windows 7. UEFI boot is supported but many IT departments prefer to leave UEFI boot disabled to preserve compatibility with operating system images.

Windows 7 and Windows 8 Dual boot

As secure boot is not supported by Windows 7, this will need to be disabled. Leave UEFI boot disabled if you prefer to maintain compatibility with non-UEFI software images.

Windows Vista

Windows Vista does not support Secure boot or UEFI boot. These need to be disabled for Windows Vista.

I Have Changed the Motherboard in the System and Windows won't Start

In this situation, it is best to configure the BIOS to the recommended secure boot and UEFI settings depending on the operating system that is installed on the machine.

What If I want to Boot from a Hard Disk Larger than 2TB?

If you want to boot from a hard disk larger than 2TB, you need the following:

• UEFI to be enabled in the BIOS
• The disk must be partitioned as GPT (if you try and install Windows when UEFI only mode has been selected, this partitioning method is usually selected automatically).
• You need a UEFI compliant version of Windows - Windows 7 is capable; Windows 8.1 is recommended. Windows XP and Windows Vista are not UEFI capable.

Remember: If you want to use UEFI boot with Windows 7 or Windows 8, then UEFI boot should be turned on before you install the operating system. If you want to share an operating system images between machines, the UEFI, Secure boot and SATA controller mode settings should be identical between the machines.

Applies to:

• Desktop and laptop systems with 6, 7 or 8 series motherboards.

We do not recommend that you update your BIOS unless you have a specific problem that needs resolving. In this instance, please contact Stone support for assistance. We can help you diagnose any problem, and can give you all of the information you need for any BIOS update.

If you would like to try the BIOS update on your own, these are made available when necessary on the Stone driver finder - Stone Driver Finder.

Note: BIOS files available on the driver finder will not include any BIOS customizations that may have been set up for you when you purchased your machine. Please make a note of important BIOS settings, such as SATA controller mode (AHCI or IDE mode) before attempting the upgrade.
