Gooday Gaming Guests - Xbox 360 PHATS Boot and Motherboard Names

Episode Date: December 26, 2024

Today I used Flash my new Gemini AI Buddy.

Alright so today I decided I was going to do Xbox 360's for the boot up process. But then I ran into a problem with ChatGPT. It's not coming on. So I decided to come over to Gemini which I haven't really spent much time with. And we'll see what kind of answers we get from this. So we're going to say the boot process of a original of a that 360. let's see what happens here i've hardly ever used genma let's see what happens all right so the boot process of an xbox 360 including the fat models this complex multi-stage process designed with security in mind here is a breakdown so every one system that I've done so far

has been very low-tech. I did all the early Ataris. I did all the early Nintendos. We were doing PS2s yesterday, which are a little bit more. And I've done PS1s. I believe I did those. So let's see what the boot is for the 360 the initial code executed when a console powers on it

resides in a small ROM the 1 BL performs basic hardware initializations and checks the integrity of the next bootloader 2BLs slash 2B. It uses chirographic checks like RSA signature verifications to ensure the 2BL hasn't been tampered with. as we all know that there's xbox 360 along with the original xbox 010 through 01 through 05 there's many many uh mods out there i've never actually done one i know though i get to do some sort of wire marred with the 360 i had one once that was already wire marred, but they sold it. So I don't know what we need. So the bootlander is stored in the console's NAD

flash memory. It performs more extensive hardware initiation and sets up the system for the next stage. Crucially, it decrypts and verifies the next bootloader, 3BL slash CD, using cryptographic keys. 3BL also located in the NAND flash.

This bootloader is responsible for setting up memory management and loading the hypervision. It decrypts and verifies the hypervision while using similar cryptographic methods. So hypervision. This is a low-level piece of software that sits between the hardware and the operating system, kernel. So the kernel is the operating system. It manages system resources and forces security policies. The HyperVision is responsible for launching the 360 kernel. So the kernel is the system. Five is kernel. This is the core of the Xbox 360 operating system it provides services to applications and games the kernel loans loads the dashboard which is used to used which is

a user interface you see on the screen security member measures the Xbox 360 boot process incorporates several security measures to prevent under unauthorized code for running cryptographic signatures for all the bootloaders and hyper vision encryption bootloads hyper vision using encryption to prevent engineering and modification fuses hardware fuses on the consoles motherboard use to store critical information and a fuse causes such as cryptographic keys and console IDs. These fuse cannot be easily changed. So fuse post codes most of the boot process the 360 outputs post power on self-test codes

as dictated bus. These codes can be used for debugging initially when the boot process of an error might have occurred so there is a modification like the reset glitch hatch so that's what that is gh g no i'm sorry rgh i always say that uh rgh now i know what it means reset glitch hack. Exploited vulnerabilities in the boot process to allow unsigned code to run. These modifications often involve manipulating the timing of the reset signal to bypass security checks.

So it's like a hack of some kind. That's pretty cool. In summary, the Xbox 360's boot process is a complex chain of trust where each stage verifies the integrity of the next this design is initiated to prevent piracy and console security alright so let's find out is is is is the xbox 360 s 1439 boot any different let's see what happens here so So this is 2.0 Flash Experimental. So we're going to call Gemini, we're going to call him Flash, obviously.

Zippy is for my chat GPT, and now we're going to call him Flash here. He's already named himself as 2.0 Flash. So we'll just call him Flash. With the fundamental principles of 360, there are some differences in the S, including the 1439 variant. S model uses unified CPU-GPU chip, codename Vanhalla. That's pretty cool, so it's got Vanhalla in it. CPU on a single die, that's integrated on a single die. Nanoflash, the S model generally uses a different type of nano flash motherboard designs completely

different security update boot later boot landers updated crypto key vault the crypto keys are stored managed might. Might be different. Anti-tampering measurements. The S model specific to the 1430 mine. It's possible that there are further model refinements. Impacting of modding. It's funny how when you type in 360 to find out the boot, it automatically talks about modding anyway. Just because it's just kind of a... I might as well just let it happen.

I don't know why they would... It would be more fun. You'd probably get a lot more stuff out of it. It says the change is made more challenging for the S models than the FATs. For example, the reset glitch hack had to be adapted

to the reset glitch hack 2 to work on some S models and later versions more difficult. While the core stages of boot B1L, BL2, 3BL, HyperVision, and Kernel are the same the model s including what then had a different had difference in hardware prices how about the final e 1539 boot so that would have been the last one. So you're asking about the Xbox 3e, specifically known as the 1539. Here's a breakdown. Further hardware integration to the Winchester motherboard. The e-model uses the Winchester motherboard which further integrated from the Sys, but it also has the Corona as well as

well as a Winchester updated the boot load he had a version boot loader strengthened the anti-tappering impact of modding increased difficulty the e version was the RGH incompatibility even the RGH 2 variant you really couldn't use this thing here further enhancements the security limited mining options I was heard you can't mod the Winchester but 1539 1438 1539 There's a Corona Absolutely right Correct

Indeed Corona Motherboards found in the East 1539 Corona boards are Originally introduced in later versions Of the Xbox S And however changes in early Trinity So we're talking about Trinity Corona those ones I know Corona similar to the s RGH challenge Chrome motherboards whether er s significant challenges for the reset glitch hack

Takeaways e create equal some all right let's apologize for the initial oversimplification says what are all the names of name code name codes for um xbox sessions i really don't know still i'll kind of get them now xbox 360 uh fats what are the what are all the name code all the motherboard motherboard name codes should be like Jasper and okay here we go man I love this

new technology I can type in anything and learn in an instant outstanding alright so I asked them give me a breakdown of all the motherboard code names here we go so Exxon X-E-N-O-N, or it could be Exxon, is the first. Not attempt to address some of the opening issues of the Exxon by adding heat sink to the GPU however it was still high failure rate the Opus this was a minor revision that further tweak cooling system was common

than the Xeon then the Falcon so those, I believe those are audio video only. And then Falcon, I know Falcon is one. And those are all the 203 watts. The Falcon was 175 watt. Significant improvement in reliability. It featured a 6NM CPU and GPU which generated less heat the Jasper was a final revision of the FAT it further reduced power consumption heat output with a 6 5nm CPU same one 6 5n and GPU integrated DRAM are the most reliable of the FATs and highly sought after by modders. Xeon Reliability 1st, 2nd Opus, Falcon, Jasper. You can identify the ports by opening the console. The console has an HTM port. It's either a Zephron falcon uh jasper or jasper xeon and opus do not have um hdmi ports cool i like this because i i kind of get all this this was the last system that i still need a little bit of help with id but then there's the the Jasper let's finish what this is oh go and even the actually Gemini is pretty good I'm paying for for my chat GPT Gemini's

preyed on the ball here my flash now I got flash and zippy you can usually identify the mother both fats opening power supplies so the Xeon is 203 Zephron is 203 Then the opus is 175 Falcon 175 Jasper 150 it's a smaller one So Jasper Jasper had some onboard memory. Yeah, the Jasper had some.

You're absolutely correct. Here's what we need to know. The onboard served as a purpose of a built-in memory unit, MU, earlier models. If you want to save progress games without a hard drive capacity, consoles came with either 256 or 512 of onboard NAND memory. This was increased by 16 megabytes of flash found in those FATS models. Arcade's wireless comms featured onboard memory likely done to provide basic

stability. Jasper's one less common Jasper Pro premium or elite models had onboard memory. Benefits of onboard memory it eliminated a separate there's that little plug-in that you get the little I have one around a few of them a little white plug-in extra memory I think it's like 16 megabytes or Jasper board has smaller caps than other let's see if it remembers that if it's even under you you're very observant you're right here so the ones that the buyers want they want the they want the Jasper with the short little caps not the tall ones even with the same motherboard version Jasper manufacturers sometimes active

components no major functional difference visual cues capsizes could be a visual cue distinguish between a difference why the difference components such used multiple suppliers for components in summary it was interesting there's yes this was some more better than the other meaning the those little caps and then the caps on all systems blue the caps on all the avianza audio video definitely problem the audio video systems they always blue what happens when a cap blows loss of filtering caps are essential for filtering and smoothing the electric signal within the console when they fail they can no longer form this function efficiently.

This can lead to distortion of a video or audio signal. Holding a no picture, distortion, flickering, humming, incorrect colors. Damaged component damage. In some cases, you can adjust why this happens, age, and heat. Compactors have a limited lifetime span. That's why every system, you always got to replace caps on them. I don't know how to do it correctly,

but it's usually one of the places you have to go. Poor quality components, so cheap components. Visual inspection, bulging, dome tops leaking, discoloration, cap replacements. If you're comfortable soldering, you can replace the caps. Same voltage. Professional repair, bring it to somebody. power bricks had issues so we're just kind of sticking with the 360 now are you're absolutely the power bricks need overheating especially on those fat ones so the original 203 watts they have fans in them too if you open up is all that white goopy stuff in there just like like the consoles and the caps inside there fail as well.

Core damage. No power. Obviously signs. Flashing lights. The LED indicator may flash red or orange. No light. Loud fan noise. Sometimes the fan inside the brick might become loud, which happens very often.

Intermediate power. It turns on and off intermediately. It's important to remember the difference between the power supplies. The Zeon and the Zephron are the 203. The Opus and the Falcon are 175. Jasper is 150. And then the Slim is a 135 which is 1439 and then the E being the 1538 it's only 120 watts so you can use you can use a 203 watt with a adapter they had to one and 15 39 plus 1540 did you get put a little adapter on the end of the cable there only only two two or three watt you can

do it with the statement is incorrect poverty design for original fat model it's not compatible those models requested it gives me the cold demonstration here it's these models require 120 brick using 23 you could it could possibly damage the console So it's just saying it's saying heck no 203 wards are not compatible Why I Don't multi are adapters had

It's the first one I think I've seen my zippy or my flash here now I actually say no Where does that wire adapters? made and used all the time Kind of digging the Gemini thing here Got my Zippy flashes, huh? incredibly common because they solve

functional problems incompatibility physical differences why variety Low consumption Cheaper costs So essentially adapters are a central tool Yeah, but it gave me a code here for Python to find a list of compatible power usage water just for each model generate and it comes out to 203 it's going by it's saying but if you go on eBay you can get those little adapters for the end and you can also in what is the watts on including 1540 uses 120 volts so your Xeon the original

ones are 203 Opus slim always check the label in your console so it's trying to be like completely accurate so trying to tell you not to do that but you can't I wouldn't really run it I don't use them as a tester sometimes but if you go on eBay and put in Xbox 360 power brick adapter you'll see you know I can turn on and off the my 1540 with as well. Alright, so that's fun. So today we worked with Flash. So now I have Zippy and Flash. I may come back to Flash because this is 2.0 Flash Experimental. And it doesn't cost me anything here.

I got some good information on it. So that's pretty cool. I'm going to stick with my Zippy, but we may do some comparisons with Flash. There's other stuff here code basics for beginners that's what i really want to get into some coding and stuff trying to learn you're going to python this is head over the python oh so i'm really into that check the version windows upgrade to gemini advance let's see how much Gemini Advance is

Gemini Advance for one month I just can't keep doing these but it looks pretty cool though it's $19 a month you get with our next generation Pro 1.5 but I just

used 2 you get 2 terabytes of storage I can't afford it now but eventually I'm gonna but I just used two. Oh, you get two terabytes of storage. So I can't afford it now but eventually I'm gonna I think I will get Gemini Advanced. Seems pretty cool. Just can't afford it now. Hopefully someday my YouTube will pay off.

Or my podcast or something. Then maybe we can keep playing around. Alright, so there is a Gemini too. But if you look at my Zippy ChatGPT is $20 And then maybe we can keep playing around. Alright, so there is a Gemini 2. But if you look at my Zippy, ChatGPT is $20. But to go upgrade to ChatGPT Pro, it goes to $200.

Such a jump from $20 to $200 per month. I can barely afford the $20 in a month and then mine the $200. That's not happening. And then they just added some other features. There's Sora, which is some sort of a video generator. I'm going to work on that a little bit see what that's all about all right so that's my system we went through the 360s kind of did a quick boot process I mean there's obviously it's a significant boot process but now that there's more it's more technology it's kind of very uh vague and how it actually

all really runs but you kind of get it you kind of get it and i learned a little bit more about the names and and the wattages and all that fun stuff all right so you guys have a good night and i'll talk to you tomorrow all right bye
