Ethernet Update for Recent Macs — If you’re experiencing Ethernet problems with an iBook, a FireWire-equipped PowerBook, or a slot-loading iMac or Power Mac G4 shipped since November 1999, Apple may have a fix for you with its Ethernet Update 1.0. The update is intended to improve Ethernet reliability on uncommon network setups, usually including large unswitched 10Base-5 (thick Ethernet) or 10Base-2 (thin Ethernet) segments with unusually small interpacket gaps (the delay between transmission of Ethernet data packets) or dropouts due to high network activity (after repeated attempts to retransmit data have failed). The update is a 2.5 MB download; it requires Mac OS 9.0.4 and replaces the Mac OS ROM file – but if you aren’t experiencing Ethernet trouble, there’s no need to download this update. [GD]
