Hi There, I’ve just replaced my insternal CD drive on my imac (late 2009) with an ultra II 960gb. When I do a pram resert to detect to hardware it kills my system. The firmware or bios cannot detect the new ssd and it seems to kill the boot up process dead. I can’t even do any boot to safemode, boot in target disk mode - Anything. All I get is a white screen.
If I then disconnect the ssd the mac boots up again fine.
Anyhelp will be seriously appreciated
