   }

5. No.

p.s. We use FOG ‘vanilla’, e.g. boot.php gets send to the device

This morning i tried to capture a Lenovo Yoga e11 (consumer notebook)
When it boots to ipxe i get an errormessage:

bzImage… ok
Could not select: Exec format error (http://ipxe.org/2e008081)
Could not boot: Exec format error (http://ipxe.org/2e008081)
Could not boot: Exec format error (http://ipxe.org/2e008081)

iPXE>_

What does it mean and how to fix ?
