Hello!
I got intel i5-560m to replace my 450m. But after replacing the cpu i got black screen.
Back to 450 - everything works.
Acording to CPUID these CPU have the same family and stepping.
I use modded bios(Insyde BIOS v1.25) with efi support. 
Both modded and original bios:

I think new CPU is dead.

[Gualdimar]

so my bios should support 560m?
acording to aida64 microcode version in my bios is 02, which is the same as in the first bios of 2010.
but the last version i found is 07. сan the microcode update somehow help?

[DeathBringer]

I think it will not help.

[Gualdimar]

anyway, can you help me with updating microcode, please? version 2 release date is 20100301 and version 7 - 20180423, so i thought it will be useful for 450m too.
the original size is 0x800 and the new one is 0x1000, so i can not rewrite it with hex editor

[Gualdimar]

InsydeH2OEZE says "microcode size: 80k", which is 0x14000.
acording to MC extractor microcodes start at 0x141000 and end at 0x150400 = 0xf400 bytes.
0x14000-0xf400=0x4c00 free space?
does it mean i can just shift all microcode by 0x800 to fit the new one without any harm?

[DeathBringer]

You can use version 0x03 with the same size: cpu00020655_plat00000092_ver00000003_date20110901.bin
P.S. I'm not a tutor.

without your help i managed to update the microcode. 
updated bios attached, maybe someone will need it too.
the same way updated microcode for 20652 and 106e5 cpu (other I have not found).

I'll try 560m once again(just to be sure)

[Gualdimar]

tried installing 560m again and it worked!
so there is some point in updating microcode...

sadly I got more help reading various non-specialized forums than posting on this bios-specialized... great job guys!

OK. I was wrong.
