I don't see why it would matter to Linux if the thing was on fat since fat is owned by root traditionally.. Other than that you can't set the permissions to 640 for the thing.. That'd constitute a security risk, but one I think would be manageable if you mount the FAT partition securely. > > Could be quite useful.

WHen I have that figured out, I'll look into more complex things like having the small installation on it. Loading Linux on this thing is not likely gonna be easy. I'm thinking that the kernel will load a ramdisk image and use the proc filesystem to find the Zip drive. Once it does that it can use the thing normally in theory. => We'll see. I only have the SCSI model so I can only do the original SCSI and parallel port versions. When people see how I do it, they're welcome to send me info on how to do the same with the Zip Plus SCSI, the same with the Zip Plus parallel driver, and the IDE models.. For an idea of how I'm gonna ID this thing, each disk Linux sees on my IDE bus is listed in /proc/ide/.. In there I have ide0/ and ide1/, but I also have hda and hdc, symlinks to inside those devices.. So, I can find my hard drive by looking for WDC in /proc/ide/hd?/model. When I get the new SCSI cables I should be able to do the same with the SCSI bus and I -KNOW- what the SCSI Zip drive's ID is. That kind of thing will help me ID the drive by the device name Linux uses, which should let me access it fine. You won't likely need to do all of that for a CD-ROM. Certainly, you'd not be able to. The only reason I'm able to is that there aren't many models of Zip drive out there to contend with.
