Power Mac G4 (PCI Graphics) ROM Update -- Apple has published a Mac OS ROM file update for users of Power Macintosh G4s (PCI Graphics) who are still running Mac OS 8.6. (An easy way to tell if your G4 uses PCI graphics instead of AGP graphics is that the PCI Graphics models have their microphone and speaker jacks oriented horizontally.) The Power Mac G4 ROM 1.8.1 Update, which may be downloaded as a 2.5 MB self-mounting disk image, resolves data corruption problems Apple discovered on Power Mac G4 (PCI Graphics) models when virtual memory is turned on and eliminates a crash with Adobe Photoshop when Extensis PhotoTools installed. The problems have already been addressed in Power Mac G4 (AGP Graphics) models and in Mac OS 9, so the update is unnecessary in those cases and will refuse to install. [MHA]
