This error indicates that there are multiple DigiSystem INITs in the Extensions Folder.It can also be a 'false' error, indicating that there are too many total drivers loading in the system. For example, multiple SCSI devices, USB devices, video capture cards, etc.If there is only one DSI loaded, try removing devices. You could boot with a drive off (then power it up and mount it) or with a USB device disconnected (USB is hot-swapable, so you could plug it in after you boot).Inhibiting driver loading on a SCSI Cards (such as the ATTO-EPCI DC) may also help solve this problem.
