u50si1 upgrade for pentium t4200

[chriz74]

hello, i have this old olidata notebook with mb u50si1, chipset is sis 672m, the cpu now is a 2ghz celeron 550. I tried to mount a Pentium dual core t4200 which should work but the pc doesn't post. The bios is phoenix 1.12. Do you know of any modded bios ? I will be able to extract it a little later as I am installing W10 at the moment. I will attach the file.
