EDIT 3: It worked, L5420 is working well and running fine, had some issues with the modded cpu initially (had to file the notch some more) but it now works and what a breath of life for this near 15 year old PC/board combo. On hindsight, should have went for the E5450 for the higher clocks, but as temperatures now hover around 50s idle may not be a good idea after all. Thanks topic starter and deathbringer for the bios mods!

EDIT 2: Alright NVM, after reading carefully reply #21 by joeblack2k8 said that the bios will show 5.31 after flashing this custom mod. Guess I was overthinking and the modded bios flash went without a hitch. Now I just need to wait for the Xeon L5420 to arrive to test it out. Currently still using the stock 1.8ghz dual core with 1gb ram (4gb otw too). On a side note, I'm surprised it managed to install win 10 pro 64 bit, in as ssd though.

Edit (NOT relevant anymore refer edit 2, keeping for record purposes and reminder not to doubt self): okay I seem to be having same issue like previous poster. Tye modded bios won't stick and it's still showing 5.31. My sequence of events were like this, original 5.04 bios would not run the freedos boot method, couldn't find 5.11 like a previous poster had so could only update to latest official 5.31...after that the dos boot method worked and everything ran perfectly successful, after reboot, and another reboot loading defaults and removing cmos battery its still showing 5.31

I have 2 official post here but I have already saved 2 otherwise still totally usable computers from being e-waste. Thanks Bios-Mods!

I have a ms-7525 motherboard, I was using it with core 2 duo e7400, but today I uploaded the modded bios published by the friend of the subject and the core 2 quad q9650 with lga 775 pin and 4 cores worked perfectly without any problems. Thank you very much deathbringer from Turkey with love
