There are two kinds of read locks that I know of. In the descriptor region of the flash are permissions for each region in the flash (BIOS, GbE, ME, for example). These can write protect, and read protect, the flash regions. There is also flags for the whole flash which are set in the PCH. The BIOS sets these flags. Ross

I tried looking for an answer to this but a quick one didn't surface: when flash regions are protected, is this implemented by the flash chip itself or by the SPI logic (ie ichspi for Intel programmer)?
