I just wanted to make it clear.

what happen with kalyway. can you try also with -v ? and what you mean black screen?

what are the messages in the screen? can you take a picture of screen ? and upload it.

I want to remind you ;

If you put your SATA HDD to one of AHCI Native IDE ports. generally there are last ports such as 5th and 6th. look at the your board manual.

than you can setup the osx then you can try the new kext for SB700.

but installation will take long time!

in addition to this, please write your mainboard full name.
means can you look at the mainboard to get the model name.

for example : GA-MA78GM-S2H rev v1.1
