The 3S157 file that is provided contains neither the EFI dmg or the OS dmg. It is a 30mb dmg that when mounted contains only 4 documents and nothing else. The ASD Read Me pdf, ASD TEST RESULTS GUIDE pdf, ASD USERGUIDE pdf and the Installing ASD on a USB hard drive pdf.
All of this documentation is useless as there is not the actual 3S157 EFI or OS file provided.
If I am missing something, will be happy to change rating. Otherwise you need to take the listed 3S157 ASD software off the list of ASD software you are selling.
