Instructions:

2. Follow steps in 'Mode of Activation' below

Mode of Activation:
1. OEM (Certificate & Key) install only where bios already (or modded) contains slic 2.1
2. Add slic 2.1 to Bootloader (0.97 grldr customised by Zsmin for me) with option (Default,Alternative, Low Memory, Debug, Forceful).
3. Add slic 2.1 to Bootmgr (No grldr means less time to boot, not recommended).
4. Certificate install where you want to replace certificate only.
5. Key install where you want to replace key only.
