K9N Platinum modded bios (CPU)
#1
Hello guys.

I have a K9N Platinum SLI motherboard (ms-7250 ver. 1.0), and decided to add AM2+ CPU support.
I found a donor bios and extracted a patch from it.
Here is a picture of the extracted patch.

I extracted patch to my bios and flashed it.
Bios update was successful, but cpu is still not supported.
When i install am2+ cpu, i get a blank screen and system is stucked.
I don't know what else to do.

Donor motherboard: http://www.asrock.com/mb/NVIDIA/ALiveN570SLI-eSATA2/
My motherboard: http://www.msi.com/product/mb/K9N_SLI_Pl...o-overview

I hope somebody gives me a hint. Sad
Thanks.

Any help?
I use an AMD Athlon x2 7750 for my tests, and when booting i only get a blank screen.
AM2 CPUs operate normally.

Hi

You were right to add the 1022 microcode CPU patch. What you didn't do which is why I think the mod didn't work was replace the P6 Microcode module from the donor bios as well (This contains some extra code relating to the 1022 CPU Patch)

Try this BIOS , which has both the CPU Patch and P6 Microcode module replaced from the donor BIOS (Try at your own risk!!)

Code:

If this mod is successful , your motherboard should now technically support all of the CPU's listed here:

Let me know!

Thanks a lot for replying to my request.

I don't know whether that helps or not, but there has been a similar topic in forum talking about 1b module and agesa code.
I suspect it needs more than microcode mod.

I have seen that thread , but before I go into the complicated steps it makes sense to try the simplest things first (adding the CPU patch and replacing P6 microcode module)

Let me know how you go!

This bios don't support Athlon 7750 (it was a good donor for 1b module files), so i imported a P6 microcode from another bios myself and result was the same.
Anyway, i'm leaving home for few days due to business, and stop testing until i get back.
I'll repost here, once i need your help. Smile
Thank you.

I'm back to testing.
So, this didn't work. Since computer does not post with my cpu i believe it has to do with agesa code.
