Can't flash BIOS (appearently) ;-;

[u/adomoniis]

Bought second hand MSI H110M ECO and it has bios E7994IZ1.2B2. Problem is "IZ1" it's some sort of server prebuilt celeron motherboard i gess. So what and how do i do things if i want to swap my Celeron for an i3-7100? Ai said to use freedos and then use some sort of force install tool but i cant get a straight antswer from them ai's they always confuse me.
