I have just purchased a new Pioneer DVR-105 drive to put in my 533/G4 desktop. This new drive is faster with all types of media than the stock drive in my machine. Is there any reason I should put the old drive in the lower slot as a slave drive? (or can I?) If I just replace the existing drive with the new 105, which would be set as master, and I should be off and running. Right?? Do I need to do any firmware updrades or anything? I couldn't find any that applied to my machine on Apple's web site. Thanks for any information.
