you will need transmac trial version to read and write ideneb iso.
but you should create Extensions folder in Ideneb dvd. because it uses only mkext.
I recommend you LS8V14 drivers you can find from insanelymac forum.
it is suitable for GA-p45-* boards maybe it can support yours.
or you can search your asus board on insanelymac , your board seems popular one to run osx.
you find bios screens to change settings.

dont forget all things are experimental , it may work or not, you should try and share if it is working
to get information how to find AHCI section in bios you can also read the your mainboard manual. and you can also download from asus web site.
I hope it helps.
