Do desenvolvedor:
The iMac Firmware 2.4 Updater addresses issues that, in rare cases, prevented iMac from starting up correctly, and better handles temporary AC power fluctuations where iMac may have shutdown unexpectedly. On iMacs running Mac OS 9.0.4 or later, it also allows a FireWire mass storage device to be used as the startup disk.
