DELL Inspiron 518 Bios to support x5450 Xeon

[billycarter86]

**Props to DeathBringer for adding the microcode to the bios**

The Inspiron 518 with bios 1.0.8 has partial support out of the box for X5450.

DeathBringer has injected LGA 771 microcodes to get full support for X5450.

With these bios you will gain the full the full instruction set for the X5450 (VT-X, SSE4.1, CompareExchange128 etc)
If you own an Inspiron 518 and have an X5450, you will not be able to upgrade to Windows 10 without these instructions.

Attached are the modified bios.

Thanks DeathBringer for your time and work.

Instructions to install the bios (Very Important as Win Flash will p00p the bed if you do not pass bios name as a parameter)
1. Unpack all files to c:\bios
2. Run cmd with admin rights.
3. Do in command line: cd c:\bios
Then type in: WinFlash 7C1D1P29.BIN

This should unpack and ask you to update bios.

After installation do a restart and you should be in business!

Before and after pics included along with error if you don't follow the instructions.

BTW CPUZ reads X5450 as E5450 at top but bios and the rest of CPUZ are correct**

*****As of 11/10/2016 I was made aware by DeathBringer that these bios support all X5400 series xeons on the inspiron 518.*****

As always,
Thank you Bios-Mods community.

Tried the update, ran per instructions. Got an error message that said failed to erase. Rebooted to black screen. How can I recover this bios?

I added Intel microcodes for Asus i975X mainboard to run L5420 with full instructions like yours. However, the PC still sometimes BSOD and could not upgrade to the latest version of Windows 10. Notice that you have mentioned CompareExchange128, how to put it into Bios?

Do you have a working bios mod for a Dell Inspiron 518? The file in this post bricked a motherboard, folled directions and it failed to erase and said to check to make sure board wasn't locked and rebooted to a black screen, no post. Got a new motherboard but don't want to use this same file. Bios is the latest from dell. Just installed a Intel Xeon E5450.  Works but I want to make sure its fully supported, windows 10 64bit installed. Thanks

it failed to erase

Erasing always before writing. So this mod isn't the reason of your problem.
You should flash it in supported(!) operating system and with supported(!) CPU.
I think this WinFlash is too old and doesn't support Windows 10.
You can use awdflash in native DOS instead of WinFlash in Windows.
BTW: hardware programmer (like CH341A) can help to recover BIOS.

It was a supported CPU. Error was that it failed to fully erase before writing new bios, saying the bios was locked, but I udated the bios to 1.0.8 from dell website in windows 10 no issue. I am aware it must erase every time for bios update. What are the advantages of this hack? Only reason I ask is that it seems the Xeon cpu is working and showing up just fine. Not sure I want to risk bricking another motherboard. Thanks

but I udated the bios to 1.0.8 from dell website in windows 10 no issue.

This does not mean that it will always be so.
Make & post a screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
Also I need a screenshot of CPU-Z.

OK. I need a screenshot of HWMonitor with CPU full load.
