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 (zsmin 0.95 grldr) with various option.
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.

Advantage:
1. Fast Install
2. Single file
3. Much smaller in size
4. Slic can be added in bootmgr
5. Cert & Slic option are together.
6. Cert can be installed seperately.
7. Key can be installed seperately.

Update Vista7 Slic Ldr 1.5:
1. Key install only added.
2. Certificate install only added.
Some bug fixed.
