See my previous reply. I hadn't thought T114 BITs/BCTs would change,
but they did, and I finally found the ODMDATA location and have a fix
for this (in V2). RAM size is the same as T30, AFAICT. The ODMDATA
field I've been flashing with is 0x80098000, which s/b 2GB.
I'll poke around bugs and wikis before I send V2 to make sure my
Dalmore is really 2GB and that the ODMDATA RAM field hasn't changed
(although I remember an email thread w/HW about not changing it).

OK.
