Free60
Free60 is the successor to the Xbox Linux Project that aims to put Linux, BSD, or Darwin on the Microsoft Xbox 360 using a software or hardware based "hack". The Xbox 360 uses hardware encryption and will not run unsigned code out of the box. The project's goals were met in March 2007, when shortly after the announcement of a critical software vulnerability in the Xbox 360 Hypervisor a loader for Linux appeared, which allowed to run a Linux ported to the Xbox 360. To date, there are two Linux kernel patchsets available, one for 2.6.21 and one for 2.6.24.3. Three main Linux distributions may be run on the Xbox 360; Gentoo, Debian and Ubuntu Linux, the last two of which are easily installable to the Xbox 360 hard drive by scripts provided by members of the Free60 project. Execution Method Since executable code on the Xbox 360 is digitally signed, and runs underneath a hypervisor, an exploit or hack is necessary in order to execute homebrew code. On the Xbox 360, the first exploit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xbox Linux
Xbox Linux was a project that ported the Linux operating system to the Xbox video game console. Because the Xbox uses a digital signature system to prevent the public from running unsigned code, one must either use a modchip, or a softmod. Originally, modchips were the only option; however, it was later demonstrated that the TSOP chip on which the Xbox's BIOS is held may be reflashed. This way, one may flash on the "Cromwell" BIOS, which was developed legally by the Xbox Linux project. Catalyzed by a large cash prize for the first team to provide the possibility of booting Linux on an Xbox without the need of a hardware hack, numerous software-only hacks were also found. For example, a buffer overflow was found in the game '' 007: Agent Under Fire'' that allowed the booting of a Linux loader ("xbeboot") straight from a save game. The Xbox is essentially a PC with a custom 733 MHz Intel Pentium III processor, a 10 GB hard drive (8 GB of which is accessible to the user), 64M ...

Homebrew (video Games)
Homebrew, when applied to video games, refers to games produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs. Many consoles have hardware restrictions to prevent unauthorized development. A non-professional developer for a system intended to be user-programmable, like the Commodore 64, is simply called a ''hobbyist'' (rather than a ''homebrew developer''). Development can use unofficial, community maintained toolchains or official development kits such as Net Yaroze, Linux for PlayStation 2, or Microsoft XNA. Targets for homebrew games are typically those which are no longer commercially relevant or produced, and with lower standards in art quality, such as the Atari 2600, Nintendo Entertainment System, Wii, Nintendo 3DS, Genesis, ...

Kernel (computer Science)
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.g. CPU & cache usage, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup (after the bootloader). It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit. The critical code of the kernel is usually loaded into a separate area of memory, which is protected from access by applicati ...

Xbox 360 Software
The Xbox system software is the operating system developed exclusively for the Xbox consoles. Across the four generations of Xbox consoles, the software has been based on a version of Microsoft Windows and incorporating DirectX features optimized for the gaming console. The user interface, the Xbox Dashboard, provides access to games, media players, and applications, and integrates with Xbox Live for online functionality. Though initial iterations of the software for the original Xbox and Xbox 360 were based on heavily modified versions of Windows, the newer consoles feature operating systems that are highly compatible with Microsoft's desktop operating systems, allowing for shared applications and ease-of-development between personal computers and the Xbox line. Common features Across all four generations of the Xbox platform, the user interface of the system software has been called the Xbox Dashboard.

Bricking
A brick (or bricked device) is a mobile device, game console, router or other consumer electronic device that is no longer functional due to corrupted firmware, a hardware problem, or other damage. The term analogizes the device to a brick's modern technological usefulness. Cause and prevention Bricking a device is most often a result of interrupting an attempt to update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable. The risk of corruption can be minimized by taking all possible precautions against interruption. Installing firmware with errors, or for a different revision of the hardware, or installing firmware incompetently patched such as DVD firmware which only plays DVDs sold in a particular region, can also cause bricking. Devices can also be bricked by malware (malicious softwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Linux Sound Architecture
Advanced Linux Sound Architecture (ALSA) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware and graceful handling of multiple sound devices in a system. ALSA is released under GNU General Public License, GPL-2.0-or-later and GNU Lesser General Public License, LGPL-2.1-or-later. On Linux, sound servers, like sndio, PulseAudio, JACK Audio Connection Kit, JACK (low-latency professional-grade audio editing and mixing) and PipeWire, and higher-level APIs (e.g OpenAL, Simple DirectMedia Layer#Subsystems, SDL audio, etc.) work on top of ALSA and its sound card device drivers. ALSA succeeded the older Linux port of the Open Sound System (OSS). History The project to develop ALSA was led by Jaroslav Kysela, and was based on the Linux device driver for the Gravis Ultrasound sound card. It sta ...

Pentium III
The Pentium III (marketed as Intel Pentium III Processor, informally PIII or P3) brand refers to Intel's 32-bit x86 desktop and mobile CPUs based on the sixth-generation P6 microarchitecture introduced on February 28, 1999. The brand's initial processors were very similar to the earlier Pentium II-branded processors. The most notable differences were the addition of the Streaming SIMD Extensions (SSE) instruction set (to accelerate floating point and parallel calculations), and the introduction of a controversial serial number embedded in the chip during manufacturing. The Pentium III is also a single-core processor. Even after the release of the Pentium 4 in late 2000, the Pentium III continued to be produced with new models introduced until early 2003, and were discontinued in April 2004 for desktop units, and May 2007 for mobile units. Processor cores Similarly to the Pentium II it superseded, the Pentium III was also accompanied by the Celeron brand for lower-end versions ...

Application Programming Interface
An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into the software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

Universal Serial Bus
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers. A broad variety of USB hardware exists, including 14 different connector types, of which USB-C is the most recent and the only one not currently deprecated. First released in 1996, the USB standards are maintained by the USB Implementers Forum (USB-IF). The four generations of USB are: USB 1.''x'', USB 2.0, USB 3.''x'', and USB4. Overview USB was designed to standardize the connection of peripherals to personal computers, both to communicate with and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports, and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players, ...

Timing Attack
In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation, an attacker can work backwards to the input. Finding secrets through timing information may be significantly easier than using cryptanalysis of known plaintext, ciphertext pairs. Sometimes timing information is combined with cryptanalysis to increase the rate of information leakage. Information can leak from a system through measurement of the time it takes to respond to certain queries. How much this information can help an attacker depends on many variables: cryptographic system design, the CPU running the system, the algorithms used, assorted implementation details, timing attack countermeasures, the accuracy of the timing measurements, et ...

Xbox Live
The Xbox network, formerly and still sometimes branded as Xbox Live, is an Internet, online multiplayer video game, multiplayer gaming and digital media delivery service created and operated by Microsoft. It was first made available to the Xbox (console), Xbox system on November 15, 2002. An updated version of the service became available for the Xbox 360 console at the system's launch in November 2005, and a further enhanced version was released in 2013 with the Xbox One. This same version is also used with Xbox Series X and Series S. This service, in addition to a Microsoft account, is the account for Xbox consoles; accounts can store games and other content. The service was extended in 2007 on the Microsoft Windows, Windows platform, named Games for Windows – Live, which makes most aspects of the system available on Windows computers. Microsoft has announced plans to extend Live to other platforms such as Mobile device, handhelds and mobile phones as part of the Live Anywhe ...
