Hm? Don't think so, there _is_ a MS-6178 target and partially works:

There are some TODOs left, but it boots Linux just fine.

Are you sure this is really the MSI MS-6178? See the photo here, in my
case the ROM was _not_ soldered: http://www.coreboot.org/Image:Msi_ms6178.jpg
You seem to have a different revision (1.1 vs. 1.0) so maybe they
changed that...

I doubt it, I've been able to write coreboot images with Uniflash just
fine. The verification errors (some red "bars" instead of only green
ones) sometimes do happen to me too, but it's always reproducible for
certains boards and chips (so I think that happens when Uniflash doesn't
fully support some hardware part, or the part is stale/broken).

As noted at http://www.coreboot.org/MSI_MS-6178_Build_Tutorial I was
_not_ able to use flashrom on this board successfully, so if the flash
is indeed soldered I would not recommend to try it unless you have some
way to recover (soldering probably)...

HTH, Uwe.
