**BIOS Setup for Restore AC Power Loss:**

The Energy-Related Products Directive (ERP) is the European Commission Directive required for products sold and exported to the EU.  As such the Qotom Q750G5 does not automatically power on after a power failure.  Obviously this //feature// needs to be disabled.

On startup (quickly) press the <DEL> key to enter the BIOS Setup, go to the "Advanced" -> "IT8631 Super IO Configuration" .  Make the following changes...

  * ''Auto power on -> [Power On]''

The results should like the following screen...

\\
**BIOS Setup for Boot OS Selection (non-UEFI):**

While in the BIOS Setup as above, to enable Legacy boot, go to the "Advanced" -> "CSM configuration" menu...

  * ''Boot option filter -> Legacy only''

The results should like the following screen...

{{:userdoc:qotom-q750g5-bios-legacy-boot.png?nolink&600|BIOS Legacy Boot}}

\\
**BIOS Setup for Boot OS Selection (UEFI):**

!!UEFI Boot requires AstLinux 1.4.6 or later!! - additionally RUNNIX 0.6.10 or later is needed.

While in the BIOS Setup as above, to enable UEFI boot, go to the "Advanced" -> "CSM configuration" menu...

  * ''Boot option filter -> UEFI only''

\\
**Other BIOS Settings**

"Advanced" -> "Trusted Computing" -> "Security Device Support" => "[Disable]"

Save the above BIOS changes, reboot.

If the mSATA was pre-installed (with e.g. PFSense) you also need to setup the Boot Priorities for the USB stick correctly on the "Boot" page.\\ 
Or you can choose a temporary Boot-Device at the "Save & Exit" tab under "Boot Override" at the bottom (instead of a Boot-Menu).
