Posting Windows Xp on ppc

We are often inspired by umpc. Even though they use low performance processors, they can still function with xp.
I don't know if Xp on ppc will be a crappy one, but I think the developers have to take the intiative on developing this.
Don't worry, just do it, everyone will be your test mice.

problem is that ms never let anybody get hold of their source to compile it for other cpu's then x86 based ones which dont include arm
so the whole thing would have to be emulated
and emulating a cpu much more powerfull is never good
if you compare a 400Mhz arm based cpu's that we may have in our pda's
it's about as fast as a p1 120Mhz which also run xp pretty poorly
and when you emulate you need tons of mem and it will add layrs
making the whole xp slower then on a pentium 1 120Mhz
thats the reason why people dont wanna spend ½ year making it happen or how much it may require

EXT4 filesystems?

Hey guys, getting my A7 in the mail this week so poking around the forum and happy to see people working on some roms and stuff. I've been fooling around with many of the Samsung Galaxy S phones and can't wait to see what we can pull off with this tablet.
To the point:
EXT4... I've been seeing most devices having their file-systems converted to EXT4 to increase performance. It seems to be much better that the standard single threaded regular FS. And wouldn't a dual core processor be even more advantageous with a multithreaded FS?
Has anyone tried this or checked if the FS are already in EXT2 or 4?
Cheers

Moved to general as not android development

I would love to see Ext 4 file system on this thing. I would also like to see a full Linux OS like Ubuntu Tablet version. I think using Linux rather than Android would solve a lot of issues but Android development on tabs is much more mature.
In any case as much ways we can make this a better device the better. I love Linux but unfortunately I do not have the tech skills to help out other than to say I would like to see if this is possible too!!

[Q] Dual-booting Dell Venue 8 Pro with Android

Hi,
Is there any chance of dualbooting Dell Venue 8 Pro with Windows 8 and Android? I like Windows 8 but would also like to be able to use Android on this awesome tablet.
If not dual boot, is there any other way of using Android as virtual machine or something that provides full touch and other sensor's support?
Thanks.

Don't "think" Android. Think Linux instead. It theoretically can be done, but the fact that the UEFI is 32bit while Linux uses 64bit.
You would disable Secure Boot in the BIOS. The other issue is a lack of drivers for the touchscreen during installation.
The stress isn't worth it in my opinion. Leave the device stock as is.

I'm downloading it now since it is just an emulator running inside VirtualBox.
There are many Android games, that I've already boght and would want to be able to play on the Venue8 Pro. I'll let you know how it works out in a few hours.
EDIT: I've installed and ran the application. As it stated, it is really just an emulator VirtualBox running a stripped down Android image.
Enabling my real cam with the emulator gave me my first BSOD. Installed a few premium games that I had purchased on my real device. The frame rate in the virtual environment wasn't smooth. It was obvious that you were using an emulator. Genymotion is a very good attempt at emulating Andriod on a running PC, however this solution is not for me. It isn't a replacement for a dual-boot scenario with the native OS.

So what would you guys recommend? I have tried both BlueStacks player and an Android virual machine on my Venue 8 Pro. I really want to be running Android smoothly.

To be honest, Genymotion, is smoother than Bluestacks, since it has the Vanilla Android interface (without Samsung's Touchwiz or HTC's Sense). The problem is with trying to use the tablet's hardware such as the camera or gyroscope. The process is then not smooth and gameplay (for serious graphic intensive android games) are choppy or lagging at best. You get the feeling that it is all being emulated and not virtualized in the true sense.
I'm convinced you would have better success running Linux natively then finding a method of running Android apps as opposed to running Android on the device.
Android requires an ARM SoC processor. The Venue 8 Pro uses a full X86/64-bit processor. Therefore Android would need to be re-compiled. This isn't worth the effort in my opinion.

I'm wondering if these instructions will work for the Venue. http://forum.xda-developers.com/showthread.php?t=2321292

It looks plausible. I'd create a system image of my entire system partiotion before even attempting this.

But isn't install Linux also difficult (given the UEFI problems)? And will I be able to run Android apps smoothly on Linux somehow?

Linux to me would be easier since it already "exists" for PC. You should be able to install it in theory with a USB mouse and keyboard attached to a USB hub. Android on the other hand would simply not work "natively" with your Dell Venue 8 since it would have to be re-compiled for this purpose. I can't imagine why the source code for an Android app can't be re-compiled for Linux despite the differences in processor type.
My only desire for Android on my Tablet is to be able to play all those games that I've bought for my Samsung Galaxy Note2,
If I knew how to compile Android from source code and simply slipstream the touchscreen drivers that would be great. Let's agree to propose this to the developers in the phone section of this forum such as Cyanogem Mod so that something can be custom built for our devices.

Contrary to the above poster. There is no issue with android across architectures.
Android apps are compiled to dalvik bytecode and run within the dalvik virtual machine. Its platform independent. x86 builds of android exist. There are x86 android devices on shelves, there is android-x86 and there is android-ia. Android is also available on MIPS processors. Community ports to PowerPC have been done. As long as you have a dalvik virtual machine you can run the dalvik bytecode, problem solved.
The driver issue is a big one. x86 operating systems dont have the issue of having to target different devices. But there arent touchscreen, wifi, bluetooth or sensor drivers for all combinations of hardware out there. The asus w700 seems to be the device best off in that regard.
Theoretically it could be done for the venue though. Without those drivers though it will be unusably slow (software drawn screen etc) and interaction wouldnt be possible without external USB.

Has anyone given this a go with the Venue Pro 8 yet? The IA (Intel architecture) android project seems quite mature. You could try booting from an SD card?

I was thinking of trying that but was too afraid to run into a problem that would ruin my new tablet.

Atom x86 phones and tablets use libhoudini to be able to run arm apps, so android dual boot is theoretically possible

From what I've read, booting from an SD card is not an possible. That's what has stopped me from trying this. I'm not interested in resizing my C drive
In theory, it sounds like the Acer instructions should work on the Dell, but once you're in Android, there may be some driver issues.

There is never any guarantee of not breaking a device! Perhaps starting with a USB OTG cable and booting the USB might be a first step - without installing to the device... that is if that is possible. I know it worked on my x86-64bit laptop, but the Venue Pro 8 is 32 bit apparently?
Anyway I don't have a Venue Pro 8 of my own... perhaps there is a guide somewhere on taking a full backup of your SSD in the device (or a similar device), including all the partitions etc?

I about to take the plunge very soon. I just completed the usb part of the tut. I am gonna use the IA3 file. I guess Ill see what happens soon. I already took the time to offload my backup on a usb, initially to make more space since I got the 16gig which really left me with only 6-8 gb. Taking out the recovery partition made about 3.45 gb free from the tab.
I already disabled "Secure Boot"
After doing this and restarting this you will run into the problem about the bitlocker and needing to type in your bitlocker code from MS again. You could bypass and disable this by hitting disable bitlocker. But for the concern it will come up. I plan on making a thread for this and be the pioneer guy.
So yeah kinda scared to start it as I got this when MS store had there $99 deal.... waited for 8 hours till i got mine and hate to break it....

Dell Venue 11 pro [Baytrail version]

Ok, so basically what i am wondering is if the Dell venue [baytrail] tablets are able to upgrade their OS? I really want to purchase the Dell Venue 11 Pro but i am reluctant to because when reviewing it i discovered that it only comes with the 32-bit version of windows 8.1. I was surprised because i knew that the baytrail processor actually supports 64-bit operating systems. Its just that the current 64-bit windows 8.1 OS does not have working drivers that are compatible with the Dell venue pros :| . (How convenient for me).
Basically what i am hoping is to get an answer from a person who already owns one or knows a little bit more about it. Are the venue pros capable of having their operating system wiped and having anything installed on it? IE. Ubuntu, or some other linux distro? because if this is the case then that would mean once a driver comes out that supports baytrails processor for the 64-bit version that customers with already purchased tablets can easily re-install the 64-bit version.
Just to note, so far i talked to some people from dell but they said i could not upgrade the OS. So, now i am going to try my luck with the tech department. Im hoping they will know a lot more about this.
Also, the reason i am wanting this tablet is so that i can program on it as well as take notes for my classes. I am currently going for a computer engineering degree with the computer science route @ Texas A&M- College station.
If anything, if i get enough taxes back i will purchase the the i3 version or maybe the surface pro 2. Im not sure yet =_= but that is a discussion for another thread. (basically i would like to be able to run unity, or blender on the tablet, and i know those programs are to processor intensive to run on an atom processor)

Unity or blender, sounds like you would be better off skipping tablets and actually getting a laptop or bare minimum something like the aforementioned surface pro 2.

I have actually thought of using a team viewer app so that i can connect to my desktop when wanting to deal with unity....im just not sure if team viewer will support touch input :S . As for the tablet i just want it to be capable on its own. The baytrail can run full windows application so if team viewer does not support touch throughput then maybe something else will. I also want a tablet that can be self capable of course. So far from what i have read, the CPU seems to be superior to all ARM processors. But, unfortunately the graphics are terrible when compared to the latest arms. So that is why i am also wondering. Should i wait till the end of 2014 to buy a cherry trial tablet?
Cherry trail will be the next generation in the atom processors that will have a faster cpu and will have 4 times the graphics cores... so hopefully up to 4 times the graphics capabilities which will put it well ahead of all current arm processors. Even the upcoming Snapdragon 805 processor!
the main downfalls for me that are preventing me from getting a Dell Venue pro 11 are three things. First, that its on 32-bit windows, second it only has 2GB of ram, and third that the graphics on the tablet are terrible!
So all that aside.... should i wait for the cherry trail version of the Dell venue 11 pro? or wait for the 64-bit version of the baytrail venue pro with upgraded ram comes out... (if it comes out)

Hardware requirements for Android studio 2.1

Hi Everyone,
I wish to start learning android development in android studio but I have a major concern about the hardware requirements. I have two machines at hand, First one is a very old desktop with an athlon 64 2800+ single core with just 2.5GB ram and Windows xp sp3 which i know would be a big no. Second one is a new HP laptop with 5th gen core i3 and 4GB ram on windows 10. I wish to know, if the laptop will be able to run it with reasonable performance or if I should certainly look at upgrading the desktop. The problem is that I can't afford the latest hardware for desktop so I will be looking at some used hardware online. I am getting some affordable deals on a used AMD phenom II X2 555 and an AMD Phenom 9550 quad core, both coupled with decent motherboards. So basically its between the laptop and those phenom processors. Which way will it be better?

I think the laptop will run it. I've tried making app on a very old pc with barely 1 or 2 gb ram and successfully completed till the basic "hello world" app. Runs very slow though. But i think your laptop is good enough for app building

Thanks a lot Simranjit, really appreciate your inputs.

I'd say your notebook shoud run Android Studio quite ok. Don't expect great performance though. Especially if you plan on using original Emulators, they are eating RAM like dogs.
I'm running AS on my 8 years old computer with Core2 Duo E6400 and 4Gb of RAM. Works ok, but not ligthing fast.
I've recently added an SSD to the configuration. Boy, that did speed things up! So, consider getting SSD if you will buy a new system. Or installing it to your notebook will also definitely boot overall system performance and loading times.

In Linux, (SWAP)
In Windows, (Paging File)
This can be considered equal to RAM and can actually be used as a substitute.
It is possible with a big enough SWAP or Paging file to use really old HW, your build-times will suffer but it's feasible if it has to be done.

Let me give you the respect of a truly proper reply. Since you're actually buying stuff....
1 ) Hardware
CPU: Intel Pentium G4400 - 60$
GPU: Integrated HD510
MOBO: GIGABYTE GA-H110M-S2H - 60$
SSD: Intel SSD 600P - 70$
PSU: Standard 30$
Case: 15-30$ standard case
DDR4-2133: $40~ for 2x4GB sticks
Dual-memory is important here; the PCIE SSD will have a write speed fast enough to compensate for the dual-core CPU.
This is also a semi-future proof model too, since adding an i3-6100 at a future time will yield a huge improvement as it has 4 threads; the next biggest upgrade is an i7 which has 8 threads the i5 is insignificant in this.
This build will actually allow you to produce AOSP and things like this in under 1 hour.
IF YOU USE AN OVERCLOCK MOTHER BOARD:
G4400 can be brought to like 4.5 GHz which is insanely fast but you need a fan, i3 won't do anything for you as the non-K overclock kills hyper-threading; reducing it to being the same as a G4400.
i5 is the same as an i7 here for the same reason; no hyper-threading.
So if you could spring for an i5 you may as well go for an overclocking build.
I mean doing it either way would yield good results, but it is just a little more expensive in the MOBO area.

That is some great info. Also, I have one more doubt, the reason why I looked at those used AMD chips is that I have read a couple of times people mentioning that the AMD chips handle android studio better due to better multi threaded performance than intel. If that really is the case then I can stretch a tiny bit more and get an FX-4300 since there isn't a lot of difference here between the G4400 and an FX-4300 but, thats only if i absolutely decide to build a new PC. Right now I am having a hard time considering an entirely new machine. Actually I had to leave my job two months back after a 10 years service. I saved up money all those years so decided to take a plunge and learn android and find a new job. Though I have healthy reserves today, I am not sure how long will it take for me to learn, be productive and find a new job.
Also, I want to add that those prices are inflated here in my country. For reference, that G4400 is around 80$ due to import duties and thats an online price on Amazon. On local stores it can be even more.

That's very correct, but... well.
There is really no situation where an FX CPU will beat an Intel CPU.
I'm saying it because I love you and don't want to see you make a huge mistake.
Do not mess with future-proofing ok?
http://cpu.userbenchmark.com/Compare/AMD-FX-9590-vs-Intel-Core-i7-3930K/1812vs1487
These CPUs are roughly the same price (refurbished or used i7-3930k is fine, nobody uses them hard compared to us.)
But the 3930k has 4 more threads; it is significantly stronger in single-core power as well so naturally the workstation score will be higher; and will build an entire OS in under 35 minutes no matter what.
When paired with strong Read/Write HW such as a PCIe SSD which should be considered REQUIRED if you value your time (you should, time is money here in regard to testing) you will be able to whack a build in under 15 minutes with this kind of HW probably.
Lesser builds such as Apps will probably take a minute or less.
You can obtain a 3930k for under 200$ no problem.
You will never be able to find a FX CPU that is worth it over an intel CPU.
FX CPU require tremendous cooling power to use! They pull a ton of energy too!
You can even run Android Studio on ARM CPUs if you're really struggling cash-wise and I can make suggestions here too.
Let me accommodate you ok?
I feel you work too hard for your money to burn it on a bad choice, tell me exactly how much you're looking to spend and I will give you an EXACT list of HW that will be unbeatable.
Dude, if you need help I can absolutely direct you to someone in China who can obtain these units are an incredibly reasonable price because these things are all made in China.
They are drowning in these parts.
I can find you a 3930k for uh, around 130$?
Look, it is a very effective CPU.
http://cpu.userbenchmark.com/Compare/Intel-Core-i7-6700K-vs-Intel-Core-i7-3930K/3502vs1487
This is what I suggest you use, seriously.

If it takes you 2 hours to build, you can only test a thing 5 times a day roughly.
Because it will take a LOT of time to trouble-shoot a project, you won't be able to build back to back as soon as the next build is finished :x
Trust me, if you strengthen your HW you will advance very fast it matters a LOT.
Even to rent a Cloud VM would be acceptable, Google offers the service man
