[coreboot] How to flash my bios on Sony Vaio VGN FZ21M Laptop

[ahmet alper parker]

Hi all,

I want to replace my crappy bios with the coreboot. I looked at the
site and it states that my chipset is ok. Here is the flashrom output
on fedora 10.
-----------------------------
flashrom
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Intel ICH8M", enabling flash write... 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.
-----------------------------
I have a Sony Vaio Laptop Vgn-Fz21m. But I don't know what is it's
chip. What should I do? Any comment is wellcomed.

Best Regards
