Your right removing this jumper did fix the booting problem for some people. A few drives also had a jumper on Term power which was also thought to be a problem. However some 8x CD players will not boot anything except the UMAX system disk. I and at least several other list members were lucky enough to get one of those! Mine is in a box some where replaced with an Apple CD player sometime ago. My C500 came with the 24x matsushita and removing the sector size jumper fixed it so it boots with the 4 finger salute as someone on this list called it.Shift+option+Apple+delete keys works fine. When I installed OS 9.04 on this machine I forgot about the four finger salute and used the C key. It started right up!I was very surprised when I realized what had happened. I know this sounds like Voodoo but I have 8.6 on another partition and it does not boot with the C key. All versions of OS 9.x do! IT is the Matsushita CD-508 B.
