Hello from Gregg C Levine
So I gathered from his earlier posts on this subject, and about that
board specifically. But Adam, isn't ADLO board agnostic? By that I
mean, that it does not need to know what motherboard it is being used
on, unlike basic Linux BIOS. But, I am indeed watching this with
interest.
