Need a gifted BIOS modder (90nm support on DFI 754)

[frostedflakes]

Hello,

I recently came by a mobile 90nm Athlon64 on eBay. It was pretty cheap, so I figured why not and bought it.

The processor came in the mail today. I put it in my board, installed the heatsink, fired it up... and got nothing. The board will POST, but hangs on the DFI logo. I tried clearing the CMOS and now it won't even POST. On the speaker I get long beep, long pause.

I am using the latest beta BIOS, 10/15.

Is it possible that somebody who knows their way around the DFI UT NF3 250gb BIOS would be able to add the 2800+ 90nm low-power microcode to the BIOS. Wouldn't it be as easy as finding a laptop BIOS that has this microcode and pasting it into the DFI BIOS? Or am I seriously underestimating the complexity of this task?

I am almost certain the Acer Ferrari 3200 uses the 90nm 2800+. A BIOS is available for download on their website, and would be a perfect donor.

If anybody could help me out, I'd REALLY appreciate it. :)

Thanks,
Adam Frakes

you can't get any 90nm s754 cpus

Yes you can.. I believe they are oakvilles? :toast:

I would PM tictac maybe, see if he knows?

Would like to see the OC results of this thing! :banana:

Maybe even PM A_G if he can talk oskar into doing it ;)

sounds like voltage isnt high enough...

try this bro.

Go into bIOS with another CPU and set vCore to 1.4v... then power down... but dont clear CMOS.
Load up again and see if it runs


I hope you get this going :toast: Good luck

i think when the bios detects a new cpu it will defualt the cmos.

maybe... but until you try...

I believe it does... always worth a try though! :toast:

what's the full stepping on this chip?

Is there no voltage mods for a64 ..where you can put a thin wire in the socket to connect two pins and make it default to a higher vcore ?

I know Ive done that on my Infinity to help with cold boots..

there must be, cos Mobiles obviously default to 1.4v vs 1.5v for DTR/Desktop... whether or not it is known is the question

Ive got a couple bios's that came in modded form back in what, Oct that allow mobile a64 support. Have you tried these? They were posted in the original DFI 250UT thread.
