My Ultra 24 fan is rotating very speed and generating huge noise.
As per my diagnosis, I found that system is not able to recognize temperature, fan speed and voltages.
I've changed the motherboard also with BIOS 1.5 still my problem is not resolved.
Can any one help me on this.
I found a Bios 1.50 and used it. It worked!!!! but I found out that it is a problem of the ME.
The fan that does not stop is the one in the box not the one in the microprocesor cooler. Just follow the instructions in the manual (http://sunsolve.sun.com/data/820/820-2480-12/pdf/820-2480-12.pdf) to set up a corrupt ME you'll fix the problem.
Have a nice week end all!!!
I have the same problem - I tried everything according to the instructions but nothing helps
it says the flash process completed normally, i turn off the workstation (from front button), moved j25 from 1-2 to 2-3, waited 10...90 seconds, pulled j25 back to 1-2 - THE SAME result!! (((
As per instruction it should come to "Intel ME Setup" (prompt to press Ctrl-P) - nothing comes, all the time the same "CPU fan error"
I also followed instructions in option 2 and it worked. The fan ran normally but the machine could not boot because it could not find the boot path.
I had to enter in BIOS configuration and in Advanced->Integrated Devices, set SATA as IDE, according to document
