Hi Kumonie, Jeremy,
adding Paul and Lynxis to CC as they were initial contributors of change
Though, I do have a question I was hoping you'd be able to answer:
The Dell OptiPlex 7010 has a service mode jumper, and, from my
understanding, two ROM chips for two firmware images, the primary
one used when the service mode jumper is not set, and the secondary
one used when the service mode jumper has been set, with an
immutable firmware image. My question is, given I only have one PC
at the moment, my OptiPlex 7010, if I, say, flash a coreboot image
that won't boot, would it be possible for me to simply set the
service mode jumper from that point to safely use the second ROM
chip? If so, it would make testing much easier.
FYI, I have a 7010 that I bricked doing a Dell firmware update.
The jumper didn't help me recover (yet?). I have one other that
I'm not sure about what jumper you talking. There are 2 close to BIOS
chips RTCRST and PSWD - neither would help directly in recover form bric
I took a picture of 2 chips . First seems to be SPI which
contain BIOS and second I would say is storage for Dell bloatware that
can run various hardware tests and display useless messages . I
will insepct SOIC8 later today, but SOIC16 requires special clip which
I don't have at this point.
@Paul,Lynxis, if you flashed anything on those devices please let me
know if there is any special treatment.
Apparently  seems to be MX25L3206E  - which is well supported by
flashrom. Second seems to MX25L6406E  - I wonder how much of that
we will need - it would be great to have additional 8MB of space.
I hope to take a look at it today night - will let you know about the
