Yes, I did use the same drive and jumpers. I didn't want to! But it seemed properly methodical since I knew for a fact that the drive and CD worked together and were bootable on the 8600. Are bootable CDs any different in 7? I was guessing the boot block could be fussier somehow. I don't know.

I moved a few months back and misplaced a box of diskettes I could use somewhere. And I have zero money to buy more.

Now that I think of it, I did install 7 once before, using one of these same CD-ROM drives on an LC475. The LC ended up having other problems, but the install wasn't difficult like this. I thought maybe the SCSI was fried on the IIci (like on my SE/30) but it does boot the original hard drive I bought it with, That drive has no visible jumpers, so I don't really know how the system sees it when it boots.
