The logic board is the small motherboard inside the disc drive assembly. All fats and the earlier slims have them. You should always keep the original with the ps3.
If you don't have the original logic board, you will have to bypass to QA flag by following these steps:
1. Download and install
You must login or register to view this content.
2. Once on the downgrader, Open rebug toolbox, go to the furthest right column and enable QA toggle.
3. Go to option "restart system"
4. Once restarted you should be able to go under network settings and press (L1,L2,L3,R1,R2,DpadDown altogether) and see debug settings pop up
You are then free to install a cfw of your choice.
Keep in mind this is bypassing so you can use the ps3 without a functioning disc drive. It will not make the drive work. The only way to make it work would be to remarry the drive or install the original logic board.
