I think I'm making progress. I found a usb keyboard/mouse and booted off with ideneb 10.5.8 lite edition, changed bios to "ahci", use the following flgas busratio=20; cpus=1 and it worked. I got as far as creating partitions on the my free space but some reason I couldnt. Also, I want to research more as to what I need to do to be able to boot mac using grub, before going through with the installation. anyone has any suggestions as to what entries need to be added to grub.conf? thanks in advance.
