I am at my wits end... can anyone assist in saving my mac 8500 . Any help will be GREATLY appreciated...I attempted to instal a larger harddrive a cheetah 9 GB in my old faithful mac , it has an 80 to 50 pin adapter , when i plugged the drive in at the end of scsi cable with one of my other drives still plugged in a 4 GB , i got partial start up and crash after crash....I tried messing with the jumpers on the drive but no change then i tried moving the drive to different loacation on cable...no change...but I THINK THIS IS WHAT CAUSED PROBLEM...so i removed the drive and attemped to boot just from the 4 GB drive i got nothing at all except startup chime and i can hear the drive spinning up and setting up as usuall then nothing just grey screen....I seems as if the mac is not looking for the drive like it has forgotten what to do...Tried pram, pmu,many key commands...but nothing ..so checked drives on other mac to see if it was bad but drive is fine boots just peachy...so my question is could the auto sensing auto terminating adapter card on drive somehow jammed my poor old macs memory of how to boot ...also tried removing all ram andgot the broken glass sound then moved ram all over the slots two different chips ...nothing but the chime is back with a ram disk inserted...tried unplugging everything and letting all power drain and cuda reset...still nothing please Know of a great little trick that ive missed because this just baffles me....Ive never heard of this type of situation...can the mac in the little mac memory or rom chip or somewhere forget to look for drives..is it possible...
thanks for any and all input

PS i am going to pull a battery from another mac to see if by some freak chance it was magically eaten by the bad cheetah!

Besides zapping the PRAM, did you try actually removing the lithium battery? Take it out, eat lunch, then put it back and try again...
