A few corrections, just to help keep things straight... The PowerMac 6500 had a 603e processor, not the older non-PowerPC 68030, which was in computers such as the SE/30 and the LCIII. HFS Extended (HFS+) was released with OS 8.1. OS 8.2 was never publicly released.
That being said, I found a link which mentioned the problem you are having exactly. Apparently, it involves the 5400, 5500, 6400, and 6500. You can read the information at: http://www.macaddict.com/resources/os/macos8/bugs.html Some suggestions from the site are: Try booting to a Disk Tools disk and then mounting the CD and installing. You may be able to force the computer to boot to the CD by holding down the C key, and immediately after the Happy Mac pops up, holding down the Shift key to force the CD to load with extensions off. The writer suggested booting might be more successful if AppleTalk is enabled before booting to the CD. Hope this helps! Bryan C.
