Extra boot menu on Atom NUC DE3815TYKHE

Hi,

We are using many of the Atom NUCs for a digital signage installation. We have noticed that on some occasions when the power is cut abruptly to the unit, a different boot menu sometimes appears when power is reconnected.

The menu displays:

TYBYT10H.86A.0041.2014.1224.1255

[ESC] Normal Boot

[F2] Intel Visual BIOS

[F4] BIOS Recovery

[F7] Update BIOS

[F10] Enter Boot Menu

[F12] Network Boot

Disconnecting and reconnecting the power causes the unit to boot normally. We are using the built-in 4GB eMMC storage to run a Linux distribution.

Does anyone know how this menu can be skipped so the unit will always boot straight into the OS?

Thanks,

-Jonathan.
