*if* you are talking about the acer you reported last month and *if* i
understood your question correctly, *then* you should be able to write
the flash chip with flashrom in your linux session. your previous log
confirmed at least that erasing works. writing will almost always work
if erase works. if you read out the good contents with -r, install the
bad chip, write the previously read good content with -w, the two chips
should be identical. please ask further questions if something is not
clear.

FAILED : mcp61sm -am

Yes i am talking about the acer i reported last month..
so if i understand,  i must before flashing make a backup with the
good chip installed with the command :
[sudo flashrom -r fichier.ROM]

"The filename and his extension is it important? and is it sure there
are no risk for the good chip?"

and after i had to install the bad chip and flash it with the command

[sudo flashrom -w fichier.ROM]

But i had try to flash the bad chip with the bios that i have saved
last month and it make error to write(the command i try was [sudo
flashrom -w 61AO615.BIN],
 Erase the chip with the command [sudo flashrom -E] is ok
This night i'm at work and i have no access at my pc so i send you the
log of my attempt tomorow

Thanks for your work and your answers and  excuse me for my english (i'm french)
Good night
