hey guys, I'm wondering if there are any xbox bios' out there that will boot instantly, like the new phoenix instant boot demonstrated using windows 7?
I really want something extremely fast. currently I use ind-bios and it takes 8 seconds to boot, duing which is shows a black screen, then a blue(which is odd) screen, then proceeds into booting xbmc. I'd like to at least skip that blue part.
are there any completely open source bios' out there that I could maybe cut out a bunch from?
I know it's silly to want it to boot faster than 8 seconds, but at the very least, that light blue screen is ugly. maybe it's my config? I dunno.

I'm interested in the same thing. I currently use 2 (switchable) bioses on my xbox:

X2 5035 - I need this for forcing 480p in games. Unfortunately it loads the "x2config.ini" file from the hard drive before starting up. This adds a short delay to the boot time.

X2 4891 - this is the fastest bios I know of. You can use xbtool to remove all startup animations and logos, and there's not blue screen.

Of course, neither is open source though!

I think boot time is a massively overlooked aspect of the xbox. It's what makes the xbox so easy and convenient to use compared to a PC. Also, it's great for xbox-based MAME arcade machines - you can have the xbox boot direct to Coinops in a matter of seconds, with nothing displayed on screen during boot.

I hope to try a SSD drive in my xbox when the prices comes down enough (probably a few years away yet!) - that should effectively eliminate seek time, which should help even more.

I couldn't agree more. it's the major reason I use an xbox as opposed to a pc. because it's smaller, and more convenient in many ways. I eventually plan to upgrade the ram and possibly processor in my machine. I also use a switch to go between two bios, one of which is stock bios, and the other is ind-bios.
I'll look into X2 4891, but any other suggestions from anyone are greatly appreciated. and as I said before, open source would be nice too, because then I -know- whats going into my bios, and I can possibly get the best boot time out of it.

Ya know? As old as the xbox is now, I am surprised no one has written an open-source bios for the box.

cromwell is open source?! hm. I'll have to look into that. does it boot regular XBE's? I seem to remember one of the bios images out there stictly being used to boot linux, and cromwell sounds familiar.
how fast is it to begin with?

also, I have a question about X2 4891. if I were to embed the eeprom dump from my system into the image using XBtool, would it boot faster, since it doesn't have to read a seperate chip? just a thought.

No, only Linux XBE's. I have an idea, to modify http://xbox-linux.cv...amp;view=markup to use HalReturnToFirmware to boot regular XBE. http://forums.xbox-s...&...t&p=4637159. But my x86 assembly language is not up to par to attempt the task.

EDIT: Ignore the suggestion, Cromwell doesn't implement HalReturnToFirmware since that is M$ code.

DUH.

I meant open source bios that would not lock the user to linux, and what I'm sure the O.P. also meant.
