Hallo Stefan,

Wir könnten eigentlich deutsch sprechen ;). 

Ja, unsere Kunden benützen auch flashrom. Wir haben usere EFI shell 
flashing tool, aber die Kunden benützen das Linux Shell am liebsten, 
besonders wenn du viele Clusters/Servers flashen muss. 

Stimmt, das SPI interface in « Intel Chipset Serie 6 » ist fast wie die 
vorausgegangen. Es gibt ME protection und special « unlocking sequence » 
mit special opcodes.

Aber mein Problem ist vor diesen Sachen. « chipset_flash_enable » findet 
nicht das PCH:
        « This chipset supports the following protocols: Non-SPI. WARNING: 
No chipset found. Flash detection will most likely fail. »

und das PCH device_id (Vendor ID:0x8086, Device ID:0x244e ) existiert 
nicht in das «chipset_enables » stuct. ( mein PCH heisst Patsburg oder 
C200 chipset ). 

Wenn ich « enable_flash_ich10 » Funktion nötige, es funkioniert auch 
nicht.
        Maximum FWH chip size: 0x0 bytes        BIOS Lock Enable: 
disabled, BIOS Write Enable: disabled, BIOS_CNTL is 0x0 tried to set 0xdc 
to 0x1 on ICH10 failed (WARNING ONLY)   Root Complex Register Block 
address = 0x0   Error accessing ICH RCRB, 0x4000 bytes at 0x00000000 
/dev/mem mmap failed: Resource temporarily unavailableIch werde vielleicht 
eine neue funktion schreiben ;).
Vielen Dank.

Mit freundlichen Grüßen
Amine Rebai

nice to hear that, thank you. is it offered to your customers too?

the spi interface of the 6 series chipset is very similar to the
previous ones and as long as there is no locking in place (i am talking
about PR0-PR4 and related "security" stuff) it may already work, have
you tried it?

in case of locking in place (that might be a requirement in nowadays
chipsets due to the requirement of using the ME) flashrom would not
work yet. i am working on this problem within the scope of my google
summer of code project which should be completed by the end of summer.
dont hold your breath though please ;)
