The issue's you are talking about with the compatibility was in the G3 beige
machines and then it was only the Rev A logic boards. The iMac's and newer
machines don't care. The funny part was after I sent the last email about
this a friend called and was having the same problem. Come to find out the
drive was in slave mode, so the iMac wouldn't boot off of it. The drive
must be in master/single mode. The other issue you maybe facing is a bad
cable or a bad logic board. I've seen both of these problems cause a
similar issue.
