Motherboard: HP t5720 Thinclient 
Version Phoenix - AwardBIOS v6.00PG

I'd like the full menu. Nothing else at this point - unless of course there's some things that are easy. 
No idea if it has the 127gb limit or not - or even if I care about it.

Honestly, I'd settle for some pointers on what tools work with this. 

I've tried a dozen versions of Modbin6 on win10 and win98. It just gets stuck on wait to load bios.
awdbedit 1.25 will open it, but I can't figure out how to unlock the menu items - and I don't really want to risk [censored] it up.
CBROM... Seems much more advanced than I can manage. I can get the _EN_CODE.bin, but then I'm left with using a hex editor which I'm not that comfortable with.

Anyhow, thanks if you manage it.

Not easy to do these ones I assume.
Seem to be a few unanswered Phoenix - AwardBIOS v6.00PG threads.

CBROM seems easy enough. Updated the VGA rom without issue.
It's the menus that seem perplexing.

True, it was challenging when I started it few weeks ago.
I've created dedicated repository for this project. More details, tools and photos are there.
