I realised that the Dell OptiPlex 3050 Micro has NVRAM available. Use that backend, and hardcode power_on_after_fail to Disable, which is already done in cmos.default. The Lenovo ThinkPad T480 currently has no option table in coreboot, besides the CBFS one. For this, the CBFS option table has been enabled, and the build system has been modified to insert a relevant config for power_on_after_fail. Nicholas Chin informs me that Kabylake generally has legacy NVRAM, so enabling it for the T480/T480s should work, but we'll need to use it in the future anyway; better to just use CBFS now. I *could* use the CBFS backend on 3050micro as well. Signed-off-by: Leah Rowe <leah@libreboot.org>

Subject: [PATCH 03/40] lenovo/x230: set me_state=Disabled in cmos.default
|
|
|
|
I only recently found out about this. It's possible to use me_cleaner to
|
|
do the same thing, but some people might just flash coreboot and not do
|
|
anything with the ME region
|
|
|
|
With this change, the ME is set to disabled. It's my understanding that this
|
|
will accomplish more or less the same thing as me_cleaner, without actually
|
|
using that. Of course, I still recommend using me_cleaner
|
|
|
|
I saw this when I audited coreboot's git history, and saw this:
