Hi Allan,
I flashed down to the BIOS version 0326 and now the "BIOS Legacy boot selection" by [F10] works again.
I need to boot from CD/DVD via [F10] option, since in the DH87RL-setup I have always the HDD as first boot device.
Is there anything wrong with the BIOS version 0327 of the DH87RL?
I took a screenshot of the boot menu [F10] under BIOS 0327:
There is one HDD with a ms-dos disklabel (BIOS-Legacy-Boot) and one optical drive with the
SystemRescueCD with both, UEFI-Boot and BIOS-Legacy-Boot facility. (www.sysresccd.org)
It is the exactly same problem with the openSUSE13.2 bootable installation DVD.
I have two completely useless entries "Unknown Unknown" in the boot menu (BIOS 0327) then.
But the DH87RL does boot from the first BIOS Legacy boot device if I do not press [F10] at Intel boot promt,
depending on which device comes first in the Intel Visual Bios setup of the DH87RL.
In contrast, here is the same constellation with the DH87RL BIOS 0326:
