FireWire Ports

The iMac has two external FireWire IEEE 1394 ports. The features of the FireWire ports are:

• Support serial I/O at 100, 200, and 400 Mbps (megabits per second)
• Share up to 8 watts of power when the computer system is on
• Support up to 62 devices

The FireWire hardware and software provided with the iMac are capable of all asynchronous and isochronous transfers defined by IEEE standard 1394.

A generic driver for mass storage devices is included in the Mac OS ROM and in the FireWire Support extension. This driver is used only when a vendor-specific driver cannot be found. Apple recommends that users install vendor-provided drivers for maximum performance and functionality.
