Hi, Ha, I think I actually read that post - someone might have shared it with me when I first started poking at this. I found that it was hard to follow, especially starting with zero knowledge around BIOSes, but it definitely got me on the right track.
And I'll take a look at the VSSC table thing - but the reference link in that post is dead. Do you have an update?
