Quanta Freedom Firmware project

[Billy Croan]

I've been tasked with updating bioses on some machines we have which have
no manufacturer support.  They were made by Quanta I think, as part of
OpenCompute project.  I have several boards that area all physically the
same, but half of them have a different bios version, and we need them to
all match.

For testing, I took a node with the old bios version, F02_3A18, and a board
with the new one, F02_3A20, and used -r to create a bios image.

Then I used -w to write that same image back to the mobo and rebooted.  No
problem on either board...

Then I copied the images to the opposite machine, and tried a -w, and
that's when I saw:
This means we have to add special support for your board, programmer or
flash
chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail [e-mail], thanks!

So, here I am.

it may be worth mentioning that between the two machines, the CHIPNAME,
referred to as such at
https://wiki.archlinux.org/title/Flashing_BIOS_from_Linux is different.
Here's what it shows:

comparing dmidecode on the two machines only shows differences in serial
numbers, and ram slots used.  all other hardware matches, so I'm pretty
sure they're the same hardware.

Why might one show up with a different chipset for bios image?

Here's some info I've gathered on these boards.
https://docs.google.com/document/d/1qp1qBXW0Y9k_Xlj1VZ-OYmF6gfm31G00tRRXYmoP...
Th G Doc lists all three hardware types we have from Quanta.  The boards
I'm writing about in this message, for this firmware exercise are called
13-P in this document.

I have yet to see any actual manual for this hardware.  tarball attached
has firmware as captured on both machines.

So.  *What might I try to gain confidence that I can freely reboot these
machines again without them being bricked?*

When I tried flashing the originally captured firmware back on it, I got
the same error message as I got when I tried transplanting the firmwares.

I did make sure that flashing the original firmware of each node back to
them didn't brick them first.  And I did make sure the firmware files were
the same size to the byte on both of them.  But it feels like the flash
storage is tainted now on GH-11 because it gets transaction errors now.

*Is there something I need to do to initialize the bios flashing chipset to
work properly?*

You've said these Quanta boards are a part of the OpenCompute project.
That means, instead of looking for a proprietary BIOS workaround,
these OCP boards - to match the OCP certification - should be ported
to open source firmware (most likely, coreboot BIOS), considering the
new requirements of OCP project regarding the firmware. Please take a
look at https://www.opencompute.org/wiki/Open_System_Firmware/Checklist
, document v1.1 from October 2020, and forward this info to your
supervisor.

> I've been tasked with updating bioses on some machines we have which have no manufacturer support.  They were made by Quanta I think, as part of OpenCompute project.  I have several boards that area all physically the same, but half of them have a different bios version, and we need them to all match.
>
> For testing, I took a node with the old bios version, F02_3A18, and a board with the new one, F02_3A20, and used -r to create a bios image.

> Then I used -w to write that same image back to the mobo and rebooted.  No problem on either board...

> Then I copied the images to the opposite machine, and tried a -w, and that's when I saw:

Before writing, flashrom reads the current flash chip contents and
only rewrites the parts that have changed. I'm pretty sure flashrom
didn't write anything in your case, you can check if `Warning: Chip
content is identical to the requested image.` appears in the log.

Without the rest of the log, this message is meaningless. Could you
please provide a full log? You can add `-o logfile.txt` to your
flashrom command to generate a debug log file. This is the preferred
method because it ensures all flashrom output gets logged: it's common
to forget about stderr when using shell redirection.

These two flash chips are equivalent and interchangeable. They're not
100% equivalent, but they have lots of things in common. For example,
they have the same size, both use the SPI protocol ("speak the same
language") and many commands are supported by both chips (including
identification commands). Using equivalent parts from different
vendors is common practice in circuit board design, as it reduces the
risk of not being able to assemble circuit boards because some
component is unavailable.

This is nothing to worry about. To choose the correct flash chip
definition in the Macronix case, the most straightforward way is to
read the model numbers written on the flash chip itself. From your
pictures, I see it's next to a corner of the ICH10R southbridge (the
square Intel chip next to the SATA ports), in a white socket.

For context, this attachment is missing because this mailing list
rejects emails with binary files attached. I just saw your messages on
IRC about your message not going through (I was sleeping when I
received them, at 4:22 AM UTC+01:00), and I imagine you simply resent
the email as-is without the attachment. In any case, firmware dumps
aren't really useful for us.

I can't say for sure without complete logs, but if flashrom didn't
print `DO NOT REBOOT OR POWEROFF!` it should be fine. Even if the
board stops booting, you can easily reflash the flash chips with an
external programmer because they're socketed.

Again, there isn't much I can say without complete logs. flashrom
refuses to flash files that are not of the exact same size as the
flash chip.
