Hello,
this is the output of flashrom:

No coreboot table found.
Found chipset "NVIDIA MCP55", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Calibrating delay loop... OK.
No EEPROM/flash device found.

While the output of lspci is attached.

Hi Alessandro,

Attached is a patch that might work for you.
Hello Luc and thanks for the patch. I used it on latest svn and I got this:

***
flashrom v0.9.1-r791
No coreboot table found.
Found chipset "NVIDIA MCP55", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Disabling flash write protection for board "Tyan S2915"... OK.
Calibrating delay loop... OK.
No EEPROM/flash device found.
If you know which flash chip you have, and if this version of flashrom
supports a similar flash chip, you can try to force read your chip. Run:
flashrom -f -r -c similar_supported_flash_chip filename

Note: flashrom can never write when the flash chip isn't found automatically.

Do I need to make something else?

Thanks,
Alex
