and you aren't able to enable ACHI from the bios... ok. well what distro did you install with? My only advice to you would be to get an IDE/SATA-to-USB adapter and install as an External HD first, then perform all the updates and install the Chameleon bootloader and the kexts and then change it to internal. This has been done before as I have searched it over at InsanelyMac using the Search Terms: "780G SB700" and selecting to view results as posts. cgsheen has been successful with it and if you were to ask, I'm sure you could get some support.
