[coreboot] How to give control to bootable USB

[Dhanasekar Jaganathan]

Hi All,

I am trying to install ONIE from USB which has ONIE installer. Actually, I
am using GRUB2 as a payload.  If Coreboot display list of bootable device,I
can select USB which will install a OS in the hard disk.  As I understood
that Coreboot won't display list of available bootable device (not like
vendor bios).I don't know how to give control to bootable USB or boot a
bootable USB by coreboot. Can you please help me on this?.

Thanks,
Dhanasekar
