Gott'a problem people -- here are the facts.
The Upgrade:
Sonnet Encore 800 MHz G4 ZIF CPU
The Mac:
Stock B&W Rev 2 - 350 MHz G3, 896 MB RAM, 6GB HD
MacOS 9.1
ROM: $77D.45F6
Boot ROM : 1.1f4
Boots into OS 9.1 with no problem
Goal: Get the 800 MHz G4 installed.
Replace the 6 GB HD with/or add a larger drive as a second HD.
Upgrade the OS to 4.1.11. And finally max the RAM to 1 GB.
What's been done:
1) Used Newertechnology B&W G4 Enabler to remove the "G4 Block"
2) Installed the Sonnet Uprade Extension for OS 9.
3) Installed the 800 MHz ZIF with the Sonnet white jumper block and special "Y"
power cable using a grounding strap -- no static zaps or sparks.
4) Checked Sonnet's jumper block setting on xcellerateyourmac web site and they
appear correct given the reduction in bus speed.
5) Checked pins on ZIF, none bent or broken
6) used contact cleaner on all connections
Problem: No bong, no boot, no video.
Additional Information:
Tried the the same upgrade on a different B &W with 300 MHz and 448 RAM same
ROM and Boot ROM and G4 Enabler installed, same HD as above; same result.
Conclusion:
1) I'm doing something incorrectly or missing a step.
2) The Sonnet G4 upgrade is TOAST!
New thought:
Maybe the Sonnet upgrade requires 9.2.2? Haven't tried that yet.
Anyone have an ideas on how to make this sucker work would be greatly
appriciated.
Or is it ready for the junk pile?
Thanks ---glen
