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.
Curious what is the use case for this? desktop or server?
I will test that port and get back to you.

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.

Thanks for the pointer on the non-F variant -- from what I can tell the BMC's RAM is physically removed which makes an exploit from the BMC side of the network virtually impossible.
If you can get this up and running it would make a great owner-controlled low-end machine. Nice find!

Maybe even FSF-endorsed. Great news! Spread the news.

This information is very much appreciated.
These boards are actually quite nice and can support up to 128 Gb of RAM. Having a Micro-ATX option in what is supported by coreboot is also nice. The CPUs can be found on ebay for as little as $5.

I assume you mean the headings near the bottom of the page. Those look like just a couple of stubs left by Marc Jones, the original author. He probably intended to document how to boot an OS from the proprietary BIOS. Not sure why.
