Absolutely!

I was only suggesting that Hao should make sure it doesn't get worse.

When I first did it, I had various versions of Windows and Linux and
*BSD working correctly. I'm still working when time allows on working
out how to get back to that state.

But right now it does at least show that it's getting correctly into
SeaBIOS and handling a bunch of requests before it crashes. As long as
it still gets that far after Hao's patches, that's fine.
