x270: use full ME (only deguard)

2026-02-20T19:33:30+00:00

to test whether this fixes the PCIe enum issue

now only deguard is used

supermicro x11ssh_f: Use deguard-configured ME image instead of SPS

2026-02-14T20:00:14+00:00

Using the same ME image as the 3050 Micro.  This fixes the lack of a
backup download URL for the ME and speeds up boot time, since MRC
caching is working with ME (unlike SPS).

Unfortunately, since the MFS partition must be preserved, this does
mean we need a larger ME region than with me_cleaned SPS.

supermicro x11ssh_f: use underscores in dir names

2026-02-14T12:58:01+00:00

i don't like hyphens in file names, because of how lbmk
has historically handled directories and files in the past;
i've removed a lot of eval statements, to the extent that
it's no longer likely to be a problem (it's barely used now),
but i previously had a problem with using hyphens in config
names.

this design flaw (in lbmk) was fixed ages ago, but i still
maintain this policy. since that time, i use hyphens only.

Add Supermicro X11SSH-F/LN4F port

2026-02-14T02:50:42+00:00

Surprisingly, SeaBIOS VGA output works (coreboot documentation says it
doesn't).

I'm using a static CMOS option table currently (like most other boards
supported in libreboot), but maybe it would be better to switch to the
CBFS file option table.  The default option table enables
hyperthreading, overriding the compile-time setting.

I'm also using a ME/SPS image extracted from the official BIOS update
for this board.  Unfortunately, https://www.supermicro.com/Bios/* is
excluded from crawlers in robots.txt so it's not in archive.org, so I
haven't been able to find a backup download URL.  I also needed to set
the user-agent for fetching the update to "curl/8.6.0" because the
default user-agent override used by lbmk resulted in a 403 error.
deguard is not required (there's no bootguard on this board).

SPS does not implement CPU replacement detection which means that the
MRC cache does not work and RAM training needs to happen on every
boot.  To avoid this it may be possible to run ME instead of SPS on
this board, but I tried both the ME image used on the OptiPlex 3050
Micro in libreboot and one from the ASRock C236 WSI and they both hung
at "[INFO ] POST: 0x92" (POSTCODE_FSP_MEMORY_INIT).

The memtest86+ build included with libreboot doesn't work with USB
keyboards and this board doesn't have a PS/2 port, which is annoying.

use newer ME on e7240

i accidentally picked an older version from Dell update
A16. this update uses A29.

2025-09-28T21:09:58+00:00

theu current comment is for an old version of the n150
patch, before it was actually merged. the comment has
been adjusted, to match the actual implementation that
was merged.
