820-2128-A any chance to find EFI/bios dump?

[premtec]

Hello,
I have a mac pro that its working backplane was sold from my customer and he has installed a non working one and brought it for repair, so far I know that everything else was working.
My only chance for fix is to test another bios [I have fixed one before].
So far I have made a dump of its TSOP40 eeprom but I was unable to find one at Internet.
Any hope for it?

What was the issue? Turns on and fans run on full?

 

[premtec]

sometimes turns on and off after few seconds and other times runs the gpu fan at full speed without turning off

I'm pretty sure this will not be a BIOS issue. If it sometimes works just fine then it could be any bad soldering/cracked trace and thus not worth fixing.

It never works ok, it only has 2 different states of failure, power and off soon after or power on and run gpu fan at full speed.
At both states it never chimes.
I know it doesn't really worth spending time at it but for a bios I'd try it.

Only common issue on these is Q1A1/A2, they are next to the HDD data/power connector. They die because of hot swapping a HDD or inserting a HDD with shorted 5V line.
