Anyone know why my Zip 100 with System 7.5.5 installed boots up my SE no problem, but not my Mac Plus? The Mac Plus powers on. For a second I get a smily face, but it then turns to a question mark after a few seconds. I have the Iomega 4.2 INIT in the system folder, but I thought you didn't need any INITs to boot a SCSI device.
