Hello Sai!

you are writing about BIOS "settings" all the time. this may be a
translation error. i just want to make clear that flashrom does not
touch/access/handle any so-called CMOS settings but the BIOS software
itself.

you probably read about a very common problem with newer boards (ICH8
and newer), but that is only slightly related to your problem. in your
case the chipset does not allow us to read the flash chip from the
start, but only starting from 0x00e00000.
The errors that follow that warning are a bit confusing to me right now.
Which flashrom version did you use? could you please provide the full
output of flashrom -V thanks.
