[flashrom] Erase failed

[Leonardo Pedretti]

Hey! sorry to bother you, i really try to help myself out, but in this case
i lack any knowledge of the details of bios memory management.
I have tried to flash the bios on my k8n Neo4 Platinum pcb v 1.0, the write
started giving errors, output follows...

flashrom v0.9.2-r1141 on Linux 2.6.32-5-686 (i686), built with libpci
3.1.7, GCC 4.4.5 20100728 (prerelease), little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
No coreboot table found.
Found chipset "NVIDIA CK804", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Disabling flash write protection for board "MSI K8N Neo4-F"... OK.
Found chip "PMC Pm49FL004" (512 KB, LPC,FWH) at physical address 0xfff80000.
Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... Erasing flash chip... SUCCESS.
