How to Update the BIOS on the Stonebook Pro or Stonebook Lite Laptops

A BIOS update is available for the Stonebook Pro and Stonebook Lite Skylake based laptops. This BIOS introduces UEFI support for Windows 7 installations. UEFI support is required for TPM (2.0) functionality on these models with Windows 7, due to a Microsoft limitation.

Note: Please only update the BIOS if necessary. The BIOS should not be updated unless you are experiencing a specific issue which requires an update. This BIOS update is designed to be used by Administrators. Contact Stone Support for further advice.

What you need to Perform the Update

You will need a copy of the BIOS file and then decide which one of the two methods to use, below. We recommend that you use the Windows 98SE DOS Bootable Pen drive method, however a Windows Flash is also available.

Method 1 - Windows 98SE DOS Bootable Pen Drive

Extract the downloaded file to the pen drive.
Ensure that the system to be updated is connected to the AC mains and also has a battery level of at least 20%.
Disable UEFI boot in the BIOS, if enabled.
Boot the system to be updated from the pen drive.
Run the FLASH batch file to flash the BIOS.
Then shut the system down if it doesn't turn off automatically.
Start the system back up and re-enable UEFI boot in the BIOS if it was previously enabled.

Note: With this method, do not attempt to use this BIOS update procedure inside a "DOS" box or command prompt inside another operating system such as Windows 10. Always run all parts of the update from a pure DOS boot.

Method 2 - Flashing from Within Windows 10

Login to the system to be updated as an Administrator.
Extract the downloaded file to C drive of the machine to be updated. Do not attempt to use the flash files from a network location.
Ensure that the system to be updated is connected to the AC mains and also has a battery level of at least 20%.
Open an Administrative Command Prompt.
Open the location containing the extracted files.
Run the WINFLASH batch file to flash the BIOS.
- This will automatically detect if you are running on x86 or x64 Windows and run the right flash utility accordingly.
Then shut the system down if it doesn't turn off automatically.

Always Note: For both methods, always ensure that the laptop is connected to the mains and that the battery has at least 20% charge before attempting to perform the flash.
