Sep 02, 2012 The 3.1 is default for a hackintosh and is best for the most compatiblity 5.1 is just telling the system it is more recent say for instance I have a 5.1 I had to delete a Kext to get it working properly but now my machine thinks it is manufactured in 2012 not 2008 which can come in handy if apple ever bring out a new operating system that is not mac pro 3.1 compatible aside from that I am not.
The chime is generated in software after the first part of the Power-On Self Test has passed. Millions of instructions have executed successfully to get you there. And you said it responds to the Eject key by opening the drawer. That is under software control as well. The caps lock light is as well. Your logic board is far from dead.
That display card does not have a stellar reputation for longevity. But BIOS support is a subset of EFI support, so it should be recognized and light up right away in a PC.
If you decide to replace it:
PC-only cards will generally not show a picture under Mac OS X.
PC cards flashed to EFI firmware will not show a picture under Mac OS X until the login screen. That makes alternate booting and debugging difficult.
original Apple-firmware cards light up shortly after power on.
If you are looking at new cards, the Apple 5770 is a good bet, but requires 10.6.5 or later.
Hello,
Im trying too fix a mac pro 2008 3,1 3.0 8core. When its starts up it gives a kernel panic.
My first thoughts where that it had a bad hdd. I plugged it in another mac as a slave disk en got all sort of damage reports when using disk utility.
Internet recovery mode
Also when i tried internet recovery it wil not instal en fresh osx.
I got out the old hdd and plugged a new (old) one in. Which was completely erased and format journaled extended.
DVD
So ive tried to boot it with a dvd system disk os x lion (command +c) but its eventually gets a hickup and unfortunately shows a round sign with a stipe. Swap out the dvd drive with another one. same thing. new disk, same thing.
USB
next thing i've tried was to make it boot with a instal usb el captain. But when i startup with alt/option pressed it doesn't recognize the usb. and that sucks big time.
Ive cleaned the whole system which was pretty dusty and dirty.
I'm not a mac specialist and little bit out of options. I just cant get this sucker to run which i really want!!
Help/advise please!
In other comments i found a guy named Dan (@danj) and hope you can help me out.
Dear @danj and @mayer, big thanx for trying to help me out, you are great sports!
History Mac Pro:
A while ago I was meeting a old friend of my how is a video editor and I told that a love to fix and collect old macs. Mostly I have experience with PPC Macs but wanted to add a Mac Pro to my collection. He said well that's a coincidence I've got to broken Mac Pro 2008. He nows using new Mac Pro 2013.
The 3.1 was his original machine and back in 2012 the mac began to have power problems he said. Mac doesn't start and he said it could spontaneously fail. A bit unreliable for a working machine :-)
He bought the other Mac Pro from a colleague /friend because he thought it was also a 3.1 and could swap the power supply. The machine turn out to be a 2.1 3.0 8 core. (Not getting any screen but thats for another time)
The 3,1 didn't run very good and you could here the fans are having a heavy job while not having much to do. I've cleaned the machine completely. It was extremely dirty you wont believe it. Now its runs a lot smoother and the power supply is much more stable. no current problem anymore
Current configuration:
- Clean 7200 HDD 320 GB (I've removed the old 2 TB HD which is not working properly a gave me the kernel panic when it's trying to boot.
- 2 ATI Radeon HD 5770 1 GB (removed one)
- 20 GB RAM - 667 MHz
He was not trying to fix it up to 5.1.
I’m not familiar with EFI flash update also.
He didn't have any old documentation dvd and hardware anymore. So bringing it back to the original status could be a challenge. On market places I could find the original 3.1 disks if necessary i think.
@mayer you asked me what (intel) mac I have:
- iMac 2.66 MHz Core Duo 2008 running El Captain
- Macbook Pro 17' 2,4 i7 2011 running Sierra
- MacBook 2009 running Snow Leopard
- MacBook Pro 2008 running Lion (unfortunately unstable hdd)
I've thought I gave you guys the best insight and information a have.
