Fwd: Intel (R) Developer Zone - Case #: 00091086 [ ref:_00DU0JBUY._500U0AExiQ:ref ]
by Elmar Stellnberger 23 Jan '14

Dear FlashRom mailing list, I have a pb dot se 2 netbook with a CG82NM10 Bios chip. The good news is that Intel was ready to give us all necessary tech docs for supporting it by flashrom. Not so good news are: - the chip is not removable so trying to write it would likely only work once - I currently don`t have time to join your programming effort Nonetheless I believe that we should at least try to offer read support for the given chip. Being able to verify the installed Bios can already be of great value when it comes to system security. If that has worked well I am also ready to venture testing a write support though I would have to ask whether and how the chip could be repaired on a failed write attempt.

Supermicro X9SCL+-F BIOS (via buspirate)
by Brian Rak 22 Jan '14

22 Jan '14

The Supermicro X9SCL+-F has an SPI programming header which lets you access the BIOS without soldering. The pinout looks something like this: (orient board so PCI slots are on the top) DI - | | - GND CS * * VCC CLK - | BIOS | - WP DO * * HOLD HOLD - | CHIP | - DO WP * * CLK VCC - | *| - CS GND * * DI (edge of board) There is also a SPI jumper (J29). I'm unsure of what this does, but I had it open while doing this (though, it seemed to work closed as well) Once connected properly, the BIOS is detected: Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) on buspirate_spi. I'm assuming everything else will work, though I'm still waiting for the initial read to complete.

Re: [flashrom] F2A85-M with flashrom

Hi, Thank you for the informations. I just tested with succes flashrom on the versions 6002, 6004, 6102, 6402. Only the 6404 version does not work with flashrom and it is the only version that has the printable character sequence "SecureBootSetup"... I still have a few things to do with coreboot. Thank you very much.

I ran into this too, and found out that F2A85M's BIOS v6404 prohibits access where v5018 (the version that was preloaded on my board) does not. I haven't tried whether any other build (5103 or 5104 or 51047 or 5202 or 6002 or 6004 or 6102 or 6402) blocks full access. To solve this problem: either downgrade or read the chip using (a breadboard and) an external programmer. > > Thanks, Best regards, > > Loic > http://hackurx.wordpress.com HTH, Idwer

For reference, here is the datasheet link posted earlier: http://www.winbond-usa.com/hq/enu/ProductAndSales/ProductLines/FlashMemory/… . The chip layout is on page 6--We're using the SOIC 208-mil package. The black dot which indicates pin 1 corresponds with a small dimple on the chip itself (and perhaps a white dot silkscreened on the mainboard PCB). IIRC this system is using the 1.8V chip, but it could be 3.3V. The procedure Cory outlined is correct, in either case. -- David Hendricks (dhendrix) Systems Software Engineer, Google Inc.
