You do not need to update pci.manifest.txt. Please first run Live update and get all three Live updates installed in succession - 1, 2 and 3. You then find and open
c:\documents and settings\all users\application data\symantec\ghost\template\common\skip.manifest.txt file and insert additional line like so:
{ 0X1002 = { 0x4391 = (0x30e3103c) } },
followed by the line already there. So you would have two AHCI devices to skip. This file is no text file so be careful with commas and brackets.
You then go to Ghost boot wizard, Winpe editor and add/remove any driver that you dont need to trigger Winpe recompile. Once complete your Winpe is ready to be used in Console and making bootable media.
Cheers.
