**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 Q190G4N-S07 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" -> "ACPI Settings" .  Make the following changes...

  * ''Restore AC Power Loss -> Power On''

The results should like the following screen...

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

While in the BIOS Setup as above, check to make sure Legacy Win7 boot is enabled, go to the "Boot" menu...

  * ''Boot OS Selection -> Legacy Win7''

The results should like the following screen...

{{:userdoc:qotom-q190g4n-s07-bios-legacy-boot.png?nolink|BIOS Legacy Boot}}

Save the above BIOS changes, reboot.

!!Note:!! On newer BIOS versions (12/2018) you might need to make the following changes, if you can't boot the AstLinux installation from an USB 2.0 stick:

In "Chipset/South Bridge/USB Configuration":

  * ''XHCI Mode -> Disabled''
  * ''USB 2.0(EHCI) Support -> Enabled''

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.
