OK.  Since you asked for it. I'll email directly to you.  When I diff the two
logs, you can blatantly see lines 59, 64, 70, ... not identical between cold &
warm boots.  And, these lines correspond to the RAM chips initialization.

I'm thinking, as I think as it's been stated in the past 3+ years, get RAM init
corrected and the rest of the hangs might likely resolve themselves.

NP here. I had bios saver installed and just had to refresh myself on how it
works.  I yanked & stored the original 256K BIOS chips and replaced them with
256K purchased from Digikey.  So I use the Digikey as repeatable burn targets
and the bios saver chip for the manufacturers BIOS.  So, when the Digikey burst
into flames, I can just replace with another.  Why wear-out the original part
is what I'm thinking.

I do have the prebuilt seabios payload.  I'm troubled as to what "VGA option
ROM" your speaking of.  I'm thinking, the menu option concerning executing VGA
ROM code.  ... i'll fiddle with this and if something gives on a warm boot,
I'll post to the list.

I believe one of the asus p2b one(s) is the template I used to get LinuxBIOS
2.0.0 working to boot into filo recently on a warm boot.  Albeit, I likely
swiped the source tree since years ago, but I do have a working bios image
here.  As to which ASUS P2B board it was, I can't recall.

>Hang in there! I'd love to see another 440BX board gaining support.

I also have a BIOS post card installed, but I don't think I need this at the
point I'm at correct?  Is there anything else I can learn/look/research into
on this code?  From what I see at this point, it's just comparing logging &
reporting?
