I have not got my google password with me here, so i will post here.
"aeBIOS" sounds more like a OS and as such, how is "aeBIOS" differant from say "DexOS" which can use BIOS from pmode ?.

Interesting... I'm working on similar thing, instead my own, is a full blown AIOS (Advanced Input / Output System) - that is, 64-bit version of sophisicated BIOS (I have already mentioned it in several of aeBIOS threads here.)

I was interested in writing the OS and BIOS within my own interest.
So, I have begun researching about AMD CPUs, i began to fell in love with it, since it's so simple to program this one than Intel 64-bit x86 CPUs.
(And, I purchased AMD Athlon 64 Venice 2.2GHz for just $40 off newegg.com last year.) and, I was wondering, why not get the most out it? And, also I'm planning Itanium emulation on this one too.

Yeah, I already got that - I may have to collect several other people's own homemade BIOS source code, so I may get some sense of how my own AIOS should boot and set 64-bit hardware IRQ (which will also be turned into 16-bit ones as it exits to boot 16-bit boot sector - possibly booting Windows 3.1 or windows 98 - I mean, any OS - but the OS that's originally created for Itanium CPU, would receive 64-bit IRQs and, AIOS would stay in Long Mode, so it would boot Itanium-based OS).

It could be longer, though, since I have decided that if I want a BIOS substitute with lot of bells and whistles, I would have to fill the BIOS flash full (in my case, my Biostar K8T80-A7's AMIC A29002 BIOS flash is sized up to 2MB, just plentiful for fancy 3D GUI and better embedded hardware drivers.)
