SSD Plus 240GB Macbook white problem

Sup everyone :slight_smile:

I’m trying to install a SSD Plus 240GB on my old macbook white, early 2008. 

Specs:

Core 2Duo 2.1 (T8100)

DDR2 4GB

Intem GMA X3100

I think it works in sata 1, but when I turn on, It appears a folder with (?). On my old HDD works fine.

I saw something about firmware update but to NVidia MCP79 chipset.

Someone can help me?

Thx
