Dell Inspiron One 19 Upgrade CPU from E7500 to LGA771 Xeon L5420
#1
Hi,

I've Dell Inspiron One 19, all in one pc, currently running Core 2 Duo E7500 (TDP: 65W) chipset G41, 
i plan to upgrade it to xeon L5420 (TDP 50W), Xeon cpu is pin modded by seller to fit into LGA775.
I need a modded bios to run this xeon.

This is the latest bios from dell version A06:
https://www.dell.com/support/home/id/en/...erId=W3JYN

following this link:
https://www.delidded.com/lga-771-xeon-microcode/
https://newsroom.intel.com/wp-content/up...idance.pdf

using hex editor, i replace:
cpu10677_plat10_ver00000705_2008-04-28_PRD_A6DB99DD.bin to cpu0001067a_plat00000044_ver00000a0b_date20100928.bin

then flash with WinRBU.exe from windows 10, the pc restart and blink for a second, then black screen for long time.
i then restart the pc and it's complaining about fail to upgrade bios failed crc.

Did you restore original BIOS?

i think bios upgrade failed with crc error, it boot fine to windows, so i don't restore the bios.

Reflash original BIOS.
Make DOS USB-stick (e.g, by Rufus), download and unzip all files for the modded version of CHECKUP7 to this DOS USB-stick.
Install your L5420, boot from this DOS USB-stick and make a photo of the screen with results.
Reboot, make & post screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0

Hi DeathBringer, thanks for helping me out on this. Original bios is now flashed, feel lucky the mobo is not bricked  Smile
I am waiting for L5420 to arrive, estimation is 1 week.
Once arrived, i'll come back and post the result of checkup7 and regedit.
