Mac OS Clones:
Supports System Software:
Note: many systems upgraded with Sonnet Encore/ZIF or Crescendo/PCI processor upgrades support OS X, although this software is not for OS X; systems upgraded with Crescendo/PCI also require Sonnet PCI X Install software to run OS X.
This unified installer installs files necessary to support various Sonnet processor upgrades in the listed applicable computers. This software is not necessary for Encore/ZIF G3 nor Crescendo/7200 upgrades. Version 2.3.1 adds support for additional Power Mac G4 ROMs, and adds full support for correct processor speed reporting under Mac OS 9 and Mac OS X for Encore/ST G4 upgrades.
This installer now also installs (or updates) the Startup Disk X control panel, and moves the original Startup Disk Control Panel to the Control Panels (Disabled) folder. This control panel enables universal switching between Mac OS 9.x and Mac OS X System Folders on systems where Mac OS X has already been installed.
Note: If you have altered the extension name (ie: added spaces to the file name) of a previously installed version of Crescendo, Sonnet Processor Upgrade, or Encore, this installer will not automatically remove the previous version. You must manually remove it from your Extensions Folder.
