I have a powerbook 5300cs that i use zip disks with and i just got a zip drive for my imac. 2 things happened. I reinstalled my powerbook OS 7.5.2 and downloaded iomega tools 2.xx. The other thing i did was share files between the imac and powerbook. The imac runs OS 9.2.2 and uses the iomega driver included in the install. Ever since these events, i cannot boot off of known, good, bootable Zip disks on my powerbook 5300cs. Please Help!
