hackpc87 Posted February 12, 2011 Share Posted February 12, 2011 I have a asus sabertooth x58 motherboard with an i7-950 processor and GTS 450. I have gone through about every forum about this and finally got snow leopard 10.6.3 to install after 2 installs that cut short. however I had to use the flags: -x -v legacy GraphicsEnabler=no cpus=4 busratio=23 PCIRootUID=1 I used mars with chameleon r4 on it to do the install and when I put it back in after the install to boot up for the first time off the HD it gave me the you have to turn of the computer by holding down the power button...notification. Anyone know how to get this to boot up. I have a DSDT that I think will work for my mb but i cant install it. Any help would be greatly appreciated cause I'm new to this. Thanks.
