Installing Llama on secondary disk for use with ellmer

Hello,

I've downloaded and installed ellmer and have successfully used to chat with Claude. I'd like to use it to access Llama. I'd also like to install Llama on a secondary drive (Satchi 4tb attached to Mac Mini) but in such a way that ellmer can access it. Could someone let me know how I might do this?

Thanks very much,

Joe
