Help! Can't boot unless i boot with cpus=1

[jamzmoby]

Hi i hope somebody can help me. If i boot without cpus=1 then i get to a black screen with just a mouse pointer. If i use cpus=1 then i get full graphics. 

I've been trying to sort this for a couple weeks now. 

My first install was using chameleon and i've now changed on a different hard drive using clover with the hope that clover being more advanced can help me sort it out. 

Sometimes i can get it to boot using Fake ID of 0x00100300 for the graphics and other times it won't boot.

 

My system is:-

 

Toshiba Satellite Pro C660

 

Intel i3 2330m cpu 

HM65 chipset

HD3000 intel graphics 2nd gen 6 series

 

It's legacy boot and Yosemite 10.10.3

 

I don't mind editing my DSDT to sort this, was just hoping with clover that i could work out the patches that was needed before editing it.

 

Thank you and i really hope someone can help me with this.
