ECC memory support
==================
The 9020 MT/SFF do not have ECC memory support. However:
Dell Precision T1700
--------------------
The T1700 is a version of the same motherboard, but with ECC support. You
can flash the 9020 MT image on this board, and it will boot.
Please note however that the native raminit (libre raminit) provided by
Libreboot does not yet support ECC. You *may* be able to use ECC modules,
but you won't actually have functioning ECC.
ECC support currently requires `mrc.bin`, which is a blob for raminit.
Libreboot removed this some time ago, instead favouring only the libre raminit.
Patches are welcome, otherwise you can use an older revision of Libreboot
with `mrc.bin` if you need ECC; it's unknown whether both the Haswell and
Broadwell MRC (the latter works on 9020 MT) both support ECC, so you'll just
have to try either. Otherwise, you might simply compile your own custom
coreboot configuration for this setup.
Libreboot's [binary blob reduction policy](../../news/policy.md) is very clear:
if a blob *can* be avoided, it must be avoided. Therefore, `mrc.bin` is avoided
since the libre raminit works pretty well these days (ECC notwithstanding).
