Hi all, I'm new in this community. My name is darmawan from Indonesia. Ok, right to the matter, does Intel ICH5 southbridge (or other newer Inte southbridge) still protects (probably mirrors) the last 8KB block (bootblock) in the BIOS chip even when the protection bits in Block Locking Registers (BLRs) has been disabled? I experienced weird results between several flashing attempts using flashrom in Linux. SOme succeeded, some retain the original values. Anyone has an explanation on the issue?
Regards, Darmawan

Some flash chips support "write protecting" their boot block (and/or other blocks). I think the data sheets have more details on this.
What flash chip are you using?
Usually if the south bridge or a GPIO does the protection, you'd be able to write all or nothing. AFAIK
