Bios Mods -The Best BIOS Update and Modification Source

[attachment=12636]
Understood, Thanks big time for your help !! And I did lower clock speed to 2.80Ghz .

What was the operating system (version) ?
I have a DP45SG and I ordered an x5450 xeon. (win10 64 bit). Can I carry out the same process?

Do BIOS patching in native DOS (not in command line from Windows).

Hallo!

Well, I have Intel DP45SG mobo and I would like to run the Xeon CPU (sc771) in it. I need to inject the 45nm CPU microcode but I dont know how to extract the 4MB bios (.rom or .bin) file from the 12MB .BIO file that I downloaded from intel web. Can anyone help me, please? 

I also tried the other way. I updated the bios to the latest from here:
https://downloadcenter.intel.com/download/18636/BIOS-Update-SGP4510H-86A-?product=34683 ===>>> file SG0125.BIO

Then I desoldered the MX bios chip from the mobo and read it with USB flasher from aliexpress. I successfully dumped the actual 4MB bios to .bin and .rom file (I always make both files, though I know they are similar) with CH341A Programmer 1.29. Verified and made another backup file with ASProgrammer 1.4.

What to do next? I know its an EFI enabled BIOS that is "capsuled". But I dont know how to extract it and get the 4MB core that I need from the 12MB capsule.

Strange thing is that when I use the MMTOOL to open any of my 4MB dumps, I get an error - Unable to read the file (100000003h). But when I open a .rom file from ASUS P5Q-VM (P5Q-VM-2101.ROM 1024kB) it opens in MMTOOL fine and I could inject the microcodes...and in the end of the day, my Xeon (sc771) works in my ASUS P5Q-VM mobo. But it only supports 1066MHz DDR2 while the DP45SG supoorts 1333MHz DDR3.

Can somebody help me? Tell me how to extract it or even better, inject the microcodes for me in that intel efi bios? So that I would just flash it again?

Thank you!

Can you boot motherboard with Xeon on native BIOS?

WOW! THANK YOU, DB!

I did not find this thread, sorry for that and I apologise for raising a thread that already exists. I can boot with Xeon but I am not able to install any operating system... the install process halts with some error... possibly right because of the missing microcode. So I guess I might be able to boot from USB in native DOS (6.22) and run the DOS tool.  I will try soon as I get home from the office.

THX again! Let you know!

By the way... is there a way to extend the compatibiliy with RAM modules...? This mobo has a wayyy short whitelist of recommanded/accepted RAM modules. It does not accept any larger than 2GB DS 1066MHz... Man, f**k that! I got 4 modules free at home, Kingston (HP) 4GB@1600MHz each. Even downgranded, ran on 1333MHz, they would have rock!

Read datasheet for P45 chipset.

Quote:Supported memory data transfer rates:
— 667 MHz and 800 MHz for DDR2
— 800 MHz and 1066 MHz for DDR3.
...
Supports 512-Mb, 1-Gb, 2-Gb DDR2 and 512-Mb, 1-Gb DDR3 DRAM technologies for x8 and x16 devices.

So it officially supports 2GB DDR3 (1066 Mhz) modules maximum (1-Gb x 16 chips).
Motherboard from other manufactures with with chipset can overclock memory to 1600 Mhz.

Hallo!


DB, thanx again, bro! Thanx for ideas and advices!
CPU:
After using the USB bootable DOS/checkupm tool, injecting the microcode...

I was able to install Windows 10 on RAID-1; 2x 128GB Apple SSD sitting on an adapter (https://www.ebay.com/itm/Sintech-dual-Ap...1149161430).
RAM:
I found four modules, 1GB@1333MHz SingleSide each... 

So now I am running Xeon E5430 (2,66GHz) with 4GB@1333MHz, nVidia GT605, 256GB RAID-1 SSDs + 1TB RAID-0. All stable with only 350W PSU! Strange thing is that though I run EFI-enabled BIOS, I was not able to boot from Ubuntu 18.x.x USB. The USB is fine, tested, works enywhere else with no problem.

Hello every body I can just boot in bios on DP45SG with X5470 then black screen white under line blinking no inter windows
How can I resolve it? How do I inter Dos for microcode injection?
