Assuming that the Zephyrod 10.5.2 Rev2 image does NOT have the SB600 southbridge patch, how do I go about making a new iso image with the patch applied? I don't have a working OSX machine right now, so would have to patch the iso using linux (or windows). I've seen some instructions on how to update the iso, but they all require a working mac. Is it simply a matter of updating the Extensions directory on the install dvd with the new contents of the SB600_SATA_ATA.zip archive? Or is there more to it than that?
