How to install Debian 10 as legacy boot mode

Hi,

I am using the tools of B&R to install Debian 10 on a PPC3100. The installation works, also the hypervisor space. But the boot mode on the new CF card is always UEFI and it should be Legacy boot mode instead…I cannot change the the boot mode under options. So my question what I need to do that the CF card has legacy boot mode.

Booting mode legacy or UEFI can be set in PPC3100 BIOS itself. As far as I know B&R offers only UEFI version of DEBIAN 10 for xPC3100. Together with hypervisor only UEFI mode is supported anyway.
