Comment(by anonymous):

 Replying to [comment:4 hailfinger]:
  There are 3 issues:

 * ICH9 PCI ID was not recognized. Fixed in r696.
 * Complains about opcode 0x06. I have a fix with correct PREOP handling,
 but this does not cause any problems except for lots of log output.
  * Transaction errors for opcode 0x03. This is actually
three different
 problems:
   * We forget to clear the transaction error flag after
a transaction
 error happens. Patch for this is upcoming.
   * The chipset does not allow us to read some areas of
the chip. No idea
 why (maybe region protection in ICH9?)
   * We don't abort after the first read error.
Needs to be fixed.
 You're right: an area is write protected by ICH9 due to current BIOS
 initialization. It's possible to read this descriptor in flash address 0
 (offset 60H).
 As the descriptor can be written by flashrom -r, I patch it and reload it
 by flashrom -w.
 Then, I must reboot so that modifications are taken into account by ICH9.
 After this reboot, it's possible to re-write the entire flash.

 Anne
