    Hello is it possible to use Iomega SCSI 250Mb Zip with System 7.x? Even make the Macintosh LC II to boot from SCSI zip drive?

    Or should i stay with Iomega SCSI 100Mb Zip? Are there possible speed issues when using 100mb disks in 250mb drive?

    Yes, apparently it is possible, but you'll need the correct driver. IomegaWare v1.1.3 is the only version that works with System 7 and seems to provide support for Zip250MB drives.

    However, there seemed to be a problem with an unimplemented trap which is as yet unresolved.

    Have a look at this thread for links to the IomegaWare installer:

    It should be able to boot from it no problem, just put the disk in the drive *BEFORE* powering on the Mac. Most removable-disk SCSI drives will, if the disk is in when starting up, report that they are a hard disk rather than a removable-disk drive.

    At least, I've used a Zip100 this way - when you do it in this order:
    1. Power on Zip drive.
    2. Insert disk.
    3. Power on computer.
    4. Computer boots from Zip disk, treating the disk as a hard drive.
