Greetings All,
I recently came across the following listing concerning Coreboot on
the Supermicro H8SCM-F.
https://www.coreboot.org/Board:supermicro/h8scm
You will note that the last update was in January of 2014. I also
noticed a note in the page concerning "OS Booting - Proprietary BIOS".
Is there anyone who can elaborate as to what this means?
I don't know, but there isn't any status update so it probably doesn't
work and that port uses AGESA so you won't get IOMMU.
I am working on porting the H8SCM and H8SCM-F (same thing really) to the
native code base, it is a nice affordable opteron board that you can get
used for $30.
Would be interested to know if you can disable the proprietary BMC? For
many coreboot use cases this would be necessary.
Thanks!
I have the version without that feature (not the -F) so I am not 100%
sure, but the vendor BIOS for mine is the -F bios and it boots fine - of
course you never really know for sure if it is "disabled" but I imagine
it functions the same as the asus boards where no ROM equals no BMC. I
will ask supermicro about this.
The difference between the -F and the regular version is the lack of the
BMC RTL NIC and the socket for the ROM chip.
The other security concern is a RMII link from the BMC chip to one of
the intel nics, which I assume is present on both models.
