| After installing an Encore/ST processor card into my computer, it won't boot or it is very unstable. | Aug-06-09 |
| Several factors may contribute to cause your upgraded system to not boot, or to have unstable operation. These include Power Mac firmware issues, incompatible PCI adapter card firmware, or an incompatible machine-specific version of Mac OS 9 may be installed. For more information, read the solutions below.
1) Update your computer's firmware.
If your computer is a Power Mac G4 (AGP Graphics), Power Mac G4 (Gigabit Ethernet) or Power Mac G4 (Digital Audio) machine, you must make sure the firmware is up to date at v4.2.8. With the processor upgrade card installed, outdated firmware can prevent the computer from booting up, or cause instability during operation. QuickSilver models already have up-to-date firmware, and should not be affected by this issue. For information on identifying your computer's model, as well as how to update firmware, refer to the quick start guide included with your Encore/ST.
2) Update the firmware of any PCI adapter card installed in your system.
Certain older PCI video cards (for a second monitor perhaps) may have outdated firmware on them that is incompatible with the new G4 chip. SCSI cards with outdated firmware and/or software are also likely candidates. To resolve the issue, you should reinstall the original processor, download any software necessary to update the PCI cards' firmware, update the firmware, and then install the Encore/ST card again.
3) Reinstall Mac OS 9.
Do the problems occur only when the system is booted in OS 9? If so, and the problems don't occur in OS X, how was the OS installed? It's possible to use installation CDs from a later machine to install OS 9 to an earlier machine. Doing so may result in the wrong ROM file being installed on the older computer; this will cause instability with the new G4 chip. If this is the case, you should reinstall Mac OS 9 from either the system's original CDs, or from a retail version of Mac OS 9, and then update the OS to 9.2.2.
4) Run the Crescendo/Encore Installer (only applies to Encore/ST G4 1.7GHz upgrade users).
Due to issues that arise from the use of recent-vintage processor chips in older systems, your computer's up-to-date firmware must be patched to make it compatible with the Encore/ST G4 1.7GHz processor card. You MUST run the Crescendo/Encore Installer before you install this Encore/ST G4 card. If you do not run the installer, your computer will not operate with the processor upgrade installed. |
