I was getting problem reports, I've created this page to list comments and hopefully resolutions on any issues that are discovered. Current installation is the primary problem area. I also want to list any performance or other improvements seen after the update as Apple promised improved PCI, Firewire, etc. Note that the code is the same as the 1.02 update so unless you had problems with that version you do not need to apply this update.
Instructions disagree on procedure.
Program's internal instructions say to release the button when you first hear the tone. Waiting until the tone is done did the job for me. In my tests after the update, I see no improvement in 64-bit PCI Ultra2 SCSI performance, Photoshop 5 performance or Rave Quake. I'm still looking for examples of the improved PCI, Firewire, etc. If you have comments on improvements, installation tips or problems to report - please contact me with specifics.
