Interesting! So 8.6 broke it. (We can assume 8.5.1 probably still had it enabled?)
I wonder what changed between those operating systems. Does 8.6 still have an iMac System Enabler? I see that 8.5 appears to have System Enabler 462 for the iMac. It contains, among other things, a single driver called .Infra (presumably for the IrDA)
Could the Mac OS ROM file have changed (8.5 has version 1.1.5), and there's something in the newer one that disables the floppy? That would probably get my first guess for where the change occurred, but I wouldn't have the first clue about hacking that file. I was hoping maybe I'd find a DRVR resource called "iMacInternalFloppy" or something that had been removed in 8.6, but no such luck
