Supports System Software:
• System 7.1.2 - Mac OS 9.1 (9.2.2 for Encore)*

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.

Emulating this? It could probably run under: QEMU
