Ok, I was able to format the zip drive using lido 7.56, but the process wasn't exactly the same as documented in the above link, even though I was using the same version of lido used by the directions. For example, it didn't ask me about the Eject on Reset.

After the SE boots, it sees the zip drive, and I've got a system folder on the zip drive, but the SE won't boot from the zip drive. According to one of the tools that came with lido, the zip disk is set as bootable.

Anyway, I'm sort of stumped at this point. The zip drive is the highest SCSI device in the chain, and I don't know what else I need to do to get the SE to boot off of the zip disk. If anyone can give me an idea of something to test or check, I'd appreciate it.

Thanks,

Nathan
