Yaboot
Yaboot (yet another boot loader) is a bootloader for PowerPC-based hardware running Linux. History In 2009, maintenance by Paul Nasrat was handed over to Tony Breeds. Hardware support Support includes the New World ROM Macintosh and IBM RS/6000 systems. It does not support the "OldWorld" PowerMacs. Booting procedure It is built to run within the Open Firmware layer common to most such systems instead of working as a Mac OS 9 program like its predecessor BootX. Yaboot is similar to LILO and GNU GRUB. Yaboot uses the following steps to boot: # Yaboot is invoked by Open Firmware # Finds a boot device, boot path and opens boot partition # Opens /etc/yaboot.conf or a command shell # Loads image or kernel and initrd # Executes image See also * Comparison of boot loaders References External links *{{Official website, http://yaboot.ozlabs.org Former official websiteon the Wayback Machine The Wayback Machine is a digital archive of the World Wide Web founded by th ...

BootX (Linux)
BootX is the name of a graphical bootloader developed by Benjamin Herrenschmidt, which runs as an application or an extension to Mac OS 8 and 9 that allows Old World Apple computers to boot Linux. It is no longer maintained by its original author, as it does not work with any current hardware, but it is still available, and further development may be possible. It is one of three Linux bootloaders which may be used on most Old World Apple computers, the others being miBoot (included, but also independently enhanced by Jeff Carr of LinuxPPC, Inc.), and quik.

Yet Another
Among programmers, yet another (often abbreviated ya, Ya, or YA in the initial part of an acronym) is an idiomatic qualifier in the name of a computer program, organisation, or event that is confessedly unoriginal. Stephen C. Johnson is credited with establishing the naming convention in the late 1970s when he named his compiler-compiler yacc (Yet Another Compiler-Compiler), since he felt there were already numerous compiler-compilers in circulation at the time.

Mac OS 9
Mac OS 9 is the ninth major release of Apple Inc., Apple's classic Mac OS operating system which was succeeded by macOS, Mac OS X (renamed to OS X in 2011 and macOS in 2016) in 2001. Introduced on October 23, 1999, it was promoted by Apple as "The Best Internet Operating System Ever", highlighting Sherlock (software), Sherlock 2's Internet search capabilities, integration with Apple's free online services known as MobileMe#iTools, iTools and improved Open Transport networking. While Mac OS 9 lacks protected memory and full pre-emptive multitasking, lasting improvements include the introduction of an automated Apple Software Update, Software Update engine and support for multi-user, multiple users. Apple discontinued development of Mac OS 9 in late 2001, transitioning all future development to Mac OS X. The final updates to Mac OS 9 addressed compatibility issues with Mac OS X while running in the Classic Environment and compatibility with Carbon (API), Carbon applications. At the ...

Initial Ramdisk
In Linux systems, initrd (''initial ramdisk'') is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs refer to two different methods of achieving this. Both are commonly used to make preparations before the real root file system can be mounted. Rationale Many Linux distributions ship a single, generic Linux kernel image one that the distribution's developers create specifically to boot on a wide variety of hardware. The device drivers for this generic kernel image are included as loadable kernel modules because statically compiling many drivers into one kernel causes the kernel image to be much larger, perhaps too large to boot on computers with limited memory, or in some cases to cause boot-time crashes or other problems due to probing for nonexistent or conflicting hardware. This static-compiled kernel approach also leaves modules in kernel memory which are no longer used or needed, and raises the p ...

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usual ...

GNU GRUB
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific Kernel (computer science), kernel configuration available on a particular operating system's partitions. GNU GRUB was developed from a package called the ''Grand Unified Bootloader'' (a play on Grand Unified Theory). It is predominantly used for Unix-like systems. The GNU, GNU operating system uses GNU GRUB as its boot loader, as do most Linux distributions and the Solaris (operating system), Solaris operating system on x86 systems, starting with the Solaris 10 1/06 release. Operation Booting When a computer is turned on, its BIOS finds the primary bootable device (usually the computer's hard disk) and runs the initial Bootstrapping (c ...

LILO (boot Loader)
LILO (Linux Loader) is a boot loader for Linux and was the default boot loader for most Linux distributions in the years after the popularity of loadlin. Today, many distributions use GRUB as the default boot loader, but LILO and its variant ELILO are still in wide use. Further development of LILO was discontinued in December 2015 along with a request by Joachim Wiedorn for potential developers. ELILO For EFI-based PC hardware the now orphaned ELILO boot loader was developed, originally by Hewlett-Packard for IA-64 systems made, but later also for standard i386 and amd64 hardware with EFI support. On any version of Linux running on Intel-based Apple Macintosh hardware, ELILO is one of the available bootloaders. It supports network booting using TFTP/DHCP.

Open Firmware
Open Firmware is a standard defining the interfaces of a computer firmware system, formerly endorsed by the Institute of Electrical and Electronics Engineers (IEEE). It originated at Sun Microsystems, where it was known as OpenBoot, and has been used by vendors including Sun, Apple, IBM and ARM. Open Firmware allows the system to load platform-independent drivers directly from a PCI device, improving compatibility. Open Firmware may be accessed through its command line interface, which uses the Forth programming language. Open Firmware is described by IEEE standard ''IEEE 1275-1994'', which was not reaffirmed by the Open Firmware Working Group (OFWG) since 1998 and has therefore been officially withdrawn by IEEE. Several commercial implementations of Open Firmware have been released to the Open Source community in 2006, including Sun OpenBoot, Firmworks OpenFirmware and Codegen SmartFirmware. The source code is available from the OpenBIOS project. Sun's implementation is av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Journal
''Linux Journal'' (''LJ'') is an American monthly technology magazine originally published by Specialized System Consultants, Inc. (SSC) in Seattle, Washington since 1994. In December 2006 the publisher changed to Belltown Media, Inc. in Houston, Texas. Since 2017, the publisher was Linux Journal, LLC. located in Denver, Colorado. The magazine focused specifically on Linux, allowing the content to be a highly specialized source of information for open source enthusiasts. The magazine was published from March 1994 to August 2019, over 25 years, before being bought by Slashdot Media in 2020. History ''Linux Journal'' was the first magazine to be published about the Linux kernel and operating systems based on it. It was established in 1994. The first issue was published in March 1994 by Phil Hughes and Bob Young, who later co-founded Red Hat, and it featured an interview with Linux creator Linus Torvalds. The publication's last print edition was August 2011, issue 208. Beginning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM RS/6000
The RISC System/6000 (RS/6000) is a family of RISC-based Unix servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and was the first computer line to see the use of IBM's POWER and PowerPC based microprocessors. In October 2000, the RS/6000 brand was retired for POWER-based servers and replaced by the eServer pSeries. Workstations continued under the RS/6000 brand until 2002, when new POWER-based workstations were released under the IntelliStation POWER brand. History The first RS/6000 models used the Micro Channel bus, later models used PCI. Some later models conformed to the PReP and CHRP standard platforms, which were co-developed with Apple and Motorola, with Open Firmware. The plan was to enable the RS/6000 to run multiple operating systems such as Windows NT, NetWare, OS/2, Solaris, Taligent, AIX and Mac OS but in the end only IBM's Unix variant AIX was used and supported on RS ...

Apple Macintosh
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by Apple Inc. Macs are known for their ease of use and minimalist designs, and are popular among students, creative professionals, and software engineers. The current lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. Macs run the macOS operating system. The first Mac was released in 1984, and was advertised with the highly-acclaimed "1984" ad. After a period of initial success, the Mac languished in the 1990s, until co-founder Steve Jobs returned to Apple in 1997. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the 2005-06 Intel transition, and brought features from the iPhone back to the Mac. During Tim Cook's tenure as CEO, the Mac underwent a period of neglect, but was later reinvigorated with the introduction of popular high-end Macs and the ongoing Apple s ...
