ASSEMblergames: Xbox Alpha II tower ! Debug, XDK, Green Discs and Art ! Prototype xbo

the xp NT kernial has been ported to the xbox

not real usable but it HAS been done

No it hasnt. Thats an attempt to run Xbox games (and such) on a PC. The graphics hardware in the XBox is modified, the CPU is modified. If it was as easy you made it seem, using off the shelf stuff, then this would be an easy task. Its not.

 

off the shelf dont mean they went out to frys and got a bunch of componets and started makeing xboxes

off the shellf also applys to desgin gess what the pIII is an x86 cpu

also no that thread is porting the NT kernial to the xbox witch the xbox already uses a modifyed version of NT

 

Again, read the link

Stop posting crap when you aren't getting it. And again, the CPU isn't just a standard CPU, nor is the graphics. Similar, yes, but the same, no.

So read the thing first, please.

 

why dpnt you read the whole thread there is also development going on for porting a more funchanial NT to the xbox

specially given the NT4 source that was leaked 10 or so years ago
is 75% complete and compilable its being worked on just read that thread and site more

i know this because ive been on that bored for a few years

its in its infacey but it is being done

 

LOL@ the back and forth. As someone who actually knows his shit for the XBox and the PC, I'll go nuts here.

The mobo looks interesting, very interesting. It looks like a vanilla ATX based mobo featuring a Slot 1 Pentium 3 (I couldn't get a good look at the numbers and the XBox has a hybrid P3 that afaik was never released to the public. 733mhz with a 133mhz FSB and 128kb of L2 made up the XBox CPU making it, more or less, a Celeron with 133mhz instead of 100mhz for the FSB. Pentium 3's back then around this time were of the Coppermine core and had 256kb of L2 cache so they are NOT simply rebadged Pentium 3's.) with an Intel chipset I'd wager though I can't actually see much of the mobo and the most interesting tidbit: A PCI video card and no visible AGP slot. There isn't any onboard video visible on the rear of the kit but there might be solder pads where an AGP bus could be installed. Rarely see an ATX mobo without AGP slots and no onboard video unless you're talking an older AT mobo.

The mobo used in the XBox uses nForce1 instead of Intel made chipsets as an AMD chip was due to go in as the main CPU which got changed at the last minute. I've never actually seen an nForce mobo myself but they are supposed to have been mass manufactured.

I can tell he has far more software experience than hardware simply by how much work he had to go through to find what he wanted. I don't think I could easily modify the various BIOSES necessary to get such a thing functional but it wouldn't be hard to assemble the hardware if I know exactly what was in the thing. The only real thing stopping you would be what likely amounts to a very short list of CPUs, mobo (likely just 1 or 2 models) and what not the BIOS supports. The XDK likely just uses Direct3D to output any video so any GeForce2 card would likely be find short of any that have small amounts of ram or an older core revision than the XBox has. Don't want to pop in a card to find out it doesn't have enough of X. Likely though as long as XP has drivers for the video card you could probably use a 6800GT IF you can get a mobo that has an AGP slot.

Given MS doesn't want to have to rely on video card x being produced for as long as they need it it makes sense to have flexibility on everything you can get away with.

Pretty sure most of the conjecture can be confirmed/denied with actual documentation but I don't have access to it.

 

thanks for the write up ape very informative i hurd rumors of MS actuialy considering AMD for the cpu

but the off the shelf was about it using common x86 cpus,chip sets, and video cards

and about it being possible but a super big pain in the ass but also possible in THEORY to use retail bios on a dev/debug and vis versa

 

If your talking about running final retail games on a alpha kit than thats not going to happen,thats why MS made dvt3's then final dvt4's.

You can talk hypothesis all day long but that doesn't make it true.

 

Ehh this guy doesn't know hes talking to pretty much the experts on the subject.
