Hi All!

I've tried flashrom on my Gigabyte GA-K8N-SLI board but it can only write to 
0x70000-0x80000. This includes both write and erase. Could you please help me 
to solve this? BTW, I don't yet have a backup chip so tested changes are 
preferred :)

Here is the probe output:

alex at tornado:~/bios$ sudo flashrom
flashrom v0.9.0+r544
No coreboot table found.
Found chipset "NVIDIA CK804", enabling flash write... OK.
Calibrating delay loop... OK.
Found chip "PMC Pm49FL004" (512 KB) at physical address 0xfff80000.
No operations were specified.

Here is the output of lshw:

I hope this helps.
