Thanks so much for digging up. I DL'd both files. Couple of questions if you can remember:
1. The literature says this for PCI X Installer:
If you already have the PCI X Installer, but have not yet installed Mac OS X on your PCI Power Mac, use this software to update to v1.2.6. Requires that the original Sonnet software (PCI X Install, Crescendo/PCI X Install, or MAXpowr PCI X Install) be present on your hard drive, and Mac OS 9.1 is installed.
Is the updater a stand alone product or does it require original PCI X Installer to work? What's interesting is the original install and updater both have same version number which is confusing.
2. I want to run this on 10.4.11 which I already have running through Xpostfacto. Do you know if this will work on 10.4.11? The literature states it works with OS 10 thru 10.2 so that's why I ask. The other reason for doing this is that I have been unable to enable my L2 cache which makes 10.4.11 run a bit sluggish. I've read where this PCI X Installer fixes that and makes the OS run faster.
