Compaq Presario R3000 add Turion and Sempron Microcode

[IrRaziel]

Hi guys. I'm restoring this vintage Compaq from 2004 (AMD version). It has socket 754 with nForce3 chipset

It born with a renamed Socket 754 Mobile Sempron (called Athlon XP-M 2800+ AHN2800BIX2AY core Dublin).
It is simply a Mobile Sempron 2800+ SMN2800BIX3AY core Dublin... fabrication 130nm and 62W TDP
In accordance with wikipedia it works at 1,4v .

I would upgrade the cpu with a 90nm 35W TDP Turion ML-32 core "Lancaster" (it has same socket, same bus hypertransport 800MHz and same voltage).
It works at 1,35v .
I think only cpu microcode in bios is missing, because I get blank screen with it. It would must work on this architecture.

Or I would upgrade the cpu with a 90nm Mobile Sempron 3000+ SMS3000BQX2LF core "Roma" 25w TDP (it has same socket, same bus 800MHz and less voltage).
I obviously also get blank screen with it, at the moment.
In accordance with wikipedia it works at 1,2v so it would not so good to work at 1,4v .

Is it possibile, please, add microcodes of these 2 cpu in the bios I attach?

With one of them I will decrease power consumption and heat, increasing performance.

I attach the last bios version... F.35

Adding microcode doesn't add support for new CPUs. Updating AGESA is needed also.
