Comment:

 Replying to [comment:1 stepan]:
 > It reads register 4e. Are you sure its not just the
 enable_flash_ich_4e() function that most other chipsets are using?

 Yes. The 0x4e is the same, but on the PIIX4 it's called XBCS instead of
 BIOS_CNTL and the bits have completely different meanings.


 > Please remember: when testing this you need to test from cold start
 because flashrom does not reset the registers to their original state.

 Thanks, will redo some tests from cold start.
