Hi.. I got this Zip drive, 100 megs. It was bundled with this system that I baught. A system that I didn't put together (since I'de probably kill it).. I install the Zip utilities and drivers.. and it doesn't find the drive. On the package (oem envelope) it says to disable auto detect in the bios and to make sure the jumper is set accordingly. I'm ready to assume that the retailer set the jumper properly (I don't want to get into that just yet).. I never really understood master and slave. I think it's something to do with the way the devices are hooked up to the mobo/cable. The end of the cable is stuck to the zip, and the middle (or second one) is stuck on the hdd. My guess was that the hdd was master, and the zip slave. I changed the bios settings, set the slave to zip 100 (didn't change anything else, was unclear, but there are a few more settings there).. I booted, nothing, it siad no master no slave.. so I switched them.. made the master the zip, and hdd slave.. same thing.. I don't know what to do to get this thing to work. I'm pretty sure that the trick is in the bios settings.. but I'm not sure.. I'm doing all of this on a A7V with the award bios. If someone has had to do the same setup, please let me know. Thanks.
