I've lost track of what total memory I can have in my blueberry 300MHz iBook. It came with 32 MB and I added a 128. I know I can switch the 128 for a 256 with a firmware update. Was there ever an firmware upgrade that would let me put a 512 in there? Thanks, Jeanne Douglas ===== ******************* ANAHEIM ANGELS 2002 WORLD SERIES CHAMPIONS
