[REQUEST] LGA 771 on old ASUS mobo

[Lionus]

hello, i recently got my hands on a XEON E5440 SLBBJ with the lga 771 to 775 sticker mod on and i wanted to put it inh my old asus motherboard, i made a copy of the BIOS and tried to put a cpu patch in it so the cpu was recognized by the mobo, but it didnt work and i cant figure out why, could someone mod my bios please ?

motherboard: ASUS P5K31 VM/S (chipset g33 but it could be g31 or p35)
installed cpu: E8200 (for some reason my E8400 doesnt work with this mobo)

 the original bios + my modifed one:
  original.ROM (Size: 1 MB / Downloads: 1)
  modified.ROM (Size: 1 MB / Downloads: 0)

1. Flash original firmware and boot with E8200.
2. Post a screenshot of Mainboard tab of CPU-Z.
3. Make DOS USB-stick (e.g, by Rufus), download and unzip all files for the modded version of CHECKUP7 to this DOS USB-stick.
4. Install your Xeon, boot from this DOS USB-stick and make a photo of the screen with results.
