[Server-devel] Fwd: [XSCE] UEFI workaround?

[Peter Robinson]

So to confirm there is no support for Secure Boot in RHEL-6 and hence
CentOS-6. For this to work you'll definitely need CentOS7.

If the NUC devices are baytrail the issue might not actually be
SecureBoot at all but rather that they have a 32 bit uEFI
implementation and that's not currently supported. Either in 32 bit
CentOS-6 (32 bit doesn't support uEFI at all) and you currently can't
boot a 64 bit OS from a 32 bit uEFI implementation even if the chip is
64 bit.
