Running OPCODE 0x03 failed at address 0x800000 (payload length was 64).
Read operation failed!

That's because 0x800000 is not covered by any region... the chipset
locks everything not covered automatically.

Thanks for your help, just missed the 0x800000 address.
Does it mean my 128Mbits flash is showed like a 64Mbits by controller due to BIOS given information ?
My BIOS fits 64Mbits anyway, can I tell flashrom to read found regions only ?

Best regards,

By the way, when trying to write (passing valid regions via a layout file),
rom / bios sizes difference seems to be a problem too :

flashrom v0.9.7-r1869 on Linux 3.13.0-24-generic (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).
