Mac Pro 1.1 (2006) NO Chime No Boot after CPUs Upgrade
I hope to have some advice about my situation with my Mac Pro 1.1..
I'm little late I know but only in these days I have had the change to upgrade my Mac.
I'm an expert user and have repaired, tweaked, hacked a lot of devices so for me Apple hardware and software are thing that i'm deal with almost every day.
This time I have decide to take time to upgrade my old:
Mac Pro 1.1 (2006)
The upgrade plan was:
- Max Ram 32Gb
- Ssd Boot HD
- Airport Extreme Card
- Mac OS X 10.9.5 with TIAMO Boot (SFOTT)
- Ati Radeon 5770 HD 1Gb (Original Apple not flashed from Pc hardware)
- Netkas 2.1 Firmware Update (since I need to upgrade CPUs for have more computing power)
I have done all of these upgrades successfully without any problems till the CPUs swap..
I have choose to upgrade my Mac Pro with a matched pair of Xeon X5365 (I've already successfully done this kind of operation a lot of times).
After I complete the CPUs swap and bring back all the inside of the Mac Pro (cleaned everything), I also changed the Logic Board Battery,
when were time to turn on, the Mac was "working" but NO CHIME and black screen.
This was the exactly sequence of events:
1) Before proceed to turn on the Mac I have reset the SMC with his own button on the Logic Board for 5 seconds
2) closed the case and attached back the AC plug
3) the Mac immediately turn on WITHOUT pressing the POWER BUTTON (light on the power button is on and stable)
4) Dvd drive turn on, front and rear fan spin normally and the HD drives other than the SSD Boot, spin.
5) No Chime - No Boot - no chance to use keyboard for a NVR reset
Checked immediately the DIAG_LED button:
Led 1 - Trickle Pwr ON
Led 6 - GPU Present ON
Led 7 - Power On ON
Led 8 - EFI Done OFF WHILE SHOUD BE ON (as stated in the Apple Service Manual) Indicates: EFI is done loading
I have try to reset again the SMC and change again the Logic Board Battery but nothing, the Mac start up but NO CHIME.
Swapped out the GPU, no chime, same with the Ram dims, I have try to pull out every dims and leave only 2 in the upper riser althought the memory riser diagnostic leds are all OFF (so no faulty dimms). Also removed Airport Card.
For test purpose I also have try to swap back the old CPUs but the things remain the same; NO CHIME, NO BOOT.
What lead me here before buy a new logic board or power supply is the LED 8 from the DIAGNOSTIC LEDs.
On every post I have find googling around NO ONE ever report the behave of the Led 8 in they'r Mac Pro:
LED 8 - EFI DONE - In my case OFF while as stated in the Apple Service Manual, should be ON.
also notice that Led 6 - GPU Present in my case the light is ON also if the GPU card is pulled out, strange uh?
Could someone here please help me to understand better what's happen to my Mac Pro?
The only other clue I can provide about a strange behave of my Mac before the upgrade is that from about a year ago after I have installed the ATI RADEON 5770 HD Instead of his standard GPU, when I hit the POWER BUTTON, before to hear the CHIME I had to what 5-10 seconds and after the Netkas 2.1 Firmware Update the time to have the CHIME was the same.
This delay of the chime sound could be related with the LED 8 EFI DONE OFF?
I also have try to PUSH the Power Button for 10 seconds for check if I eventually could be able to restore the original EFI but doesn't work, the light of the power button remain ON and don't blink.
What's happen could be related to the 2.1 Firmware Update?
I notice the the Netkas 2.1 Firmware Update for Mac Pro 1.1 in my case update only the Firmware and not the SMC (still 1.7f10), is this normal?
Thanks in advance to everyone….
