Ok, so now we know the identity of the motherboard.

Product page:
http://www.gigabyte.com/products/product-page.aspx?pid=3907#manual

Manual:
http://download.gigabyte.us/FileList/Manual/mb_manual_ga-970a-ud3_e.pdf

From reading the manual:
- this mobo uses an external TPM module (consider removing it if present)
- it talks about installing Windows XP and Windows 7 (no "secure boot" in Windows XP)
- no mention of "secure boot"
- no mention of "UEFI" (talks about EFI for booting from GPT partitions)
- latest BIOS is dated from December 2012.

From all this I conclude that this motherboard does not do "secure boot" (unless the removable TP module is present?)
and all the unspecified problems installing an non-SL operating system come from
some other source.

(I have not seen any "secure boot only" motheboards yet. If you have seen such, please let me know).
