  • Linux Kernel Series
    Linux Kernel Series By Devyn Collier Johnson More Linux Related Stuff on: http://www.linux.org Linux Kernel – The Series by Devyn Collier Johnson (DevynCJohnson) [email protected] Introduction In 1991, a Finnish student named Linus Benedict Torvalds made the kernel of a now popular operating system. He released Linux version 0.01 on September 1991, and on February 1992, he licensed the kernel under the GPL license. The GNU General Public License (GPL) allows people to use, own, modify, and distribute the source code legally and free of charge. This permits the kernel to become very popular because anyone may download it for free. Now that anyone can make their own kernel, it may be helpful to know how to obtain, edit, configure, compile, and install the Linux kernel. A kernel is the core of an operating system. The operating system is all of the programs that manages the hardware and allows users to run applications on a computer. The kernel controls the hardware and applications. Applications do not communicate with the hardware directly, instead they go to the kernel. In summary, software runs on the kernel and the kernel operates the hardware. Without a kernel, a computer is a useless object. There are many reasons for a user to want to make their own kernel. Many users may want to make a kernel that only contains the code needed to run on their system. For instance, my kernel contains drivers for FireWire devices, but my computer lacks these ports. When the system boots up, time and RAM space is wasted on drivers for devices that my system does not have installed.

This technical memorandum examines the basics surrounding computer forensic filesystem timelines and provides an enhanced approach to generating superior timelines for improved filesystem analysis and contextual awareness. Timelines are improved by polling multiple sources of information across the filesystem resulting in an approach that is surprisingly flexible and customizable. The timeline is further enhanced by incorporating key time-based metadata found across a disk image which, when taken as a whole, increases the forensic investigator’s understanding. Résumé …..... Ce mémorandum technique examine les bases entourant la création d’un calendrier des événements inforensiques des systèmes de fichier et fournit une approche améliorée pour générer des calendriers supérieurs pour une analyse améliorée des systèmes de fichiers et un meilleur éveil contextuel.

  • Disc Filing System User Guide 1983
    BBC Microcomputer Disc Filing System User Guide Addendum 1 This addendum details the differences between the Acorn 1770 Disc Filing System (DFS) and DFS 1.20 as described in the Disc Filing System User Guide Issue 2. General The Acorn 1770 DFS (DFS 2.10) is designed to be compatible with the Acorn DFS version 1.20 (and earlier versions). DES 2.10 works with a 1770 disc controller whereas DES 1.20 operates with an 8271 disc controller-. Programs/ROMs which directly access an 8271 disc controller will not work with a DFS 2.10 disc system. Most discs that work with DFS 1.20 will work with DES 2.10, obvious exceptions being protected discs which employ direct access of the 8271 disc controller. DFS 2.10 uses the same commands as DFS 1.20, but some commands have been slightly modifed, as detailed below. There is no utilities disc with DFS 2.10 -- the FORM <40/80> and VERIFY utilities which are disc-based with DFS 1.20 are filing system commands with DFS 2.10; references to a utilities disc which occur within the user guide should be ignored. DFS 2.10 contains several new commands which are not present in DFS 1.20 - see below. Throughout this text references to ROM (read only memory) should be understood to include any non--volatile memory device with ROM compatible connections and access time, such as a 2764, 27128 or 27256 EPROM with 250ns access time. DFS 2.10—only commands CLOSE Purpose Closes all sequential files. All disc file data held in RAM output buffers will be copied to the disc.

  • The Linux Kernel: Configuring the Kernel Part 16
    The Linux Kernel: Configuring the Kernel Part 16 In this article, we will discuss the input/output ports. First, the "i8042 PC Keyboard controller" driver is needed for PS/2 mice and AT keyboards. Before USB, mice and keyboards used PS/2 ports which are circular ports. The AT keyboard is an 84­key IBM keyboard that uses the AT port. The AT port has five pins while the PS/2 port has six pins. Input devices that use the COM port (sometime called RS232 serial port) will need this diver (Serial port line discipline). The COM port is a serial port meaning that one bit at a time is transferred. The TravelMate notebooks need this special driver to use a mouse attached to the QuickPort (ct82c710 Aux port controller). Parallel port adapters for PS/2 mice, AT keyboards, and XT keyboards use this driver (Parallel port keyboard adapter). The "PS/2 driver library" is for PS/2 mice and AT keyboards. "Raw access to serio ports" can be enabled to allow device files to be used as character devices. Next, there is a driver for the "Altera UP PS/2 controller". The PS/2 multiplexer also needs a driver (TQC PS/2 multiplexer). The ARC FPGA platform needs special driver for PS/2 controllers (ARC PS/2 support). NOTE: I want to make it clear that the PS/2 controllers that are discussed in this article are not Sony's game controllers for their PlayStation. This article is discussing the 6­pin mouse/keyboard ports. The controller is the card that holds the PS/2 ports.

  • 28. Óra Formázás, Fontosabb Fájlrendszerek
    2017.03.30 Összeállította: Szeli Márk 28. óra Formázás, fontosabb fájlrendszerek Formázás: A lemezformattálás (angolul disk formatting) vagy csak egyszerűen formattálás a számítástechnikában az az eljárás, ami a mágneses adattároló eszközt (merevlemezt, hajlékonylemezt) előkészíti a használatra. Amíg egy merevlemez partíció vagy egy hajlékonylemez nincs formattálva, addig nem alkalmas fájlok tárolására. Szintjei: Kétféle formázás létezik: Az alacsony szintű formattálás (low-level formatting) létrehozza a lemezeken a szektorokat, tehát kialakítja a winchester lemezeinek felszínén, hogy a szektorok hol kezdődjenek, és hol végződjenek – ez határozza meg, hogy a lemezeken hol lesznek majd tárolhatóak adatok. Ez a folyamat több órányi időt igénybe vehet, és következményeképpen a lemezen tárolt adatok – már amennyiben léteznek – megsemmisülnek. Az alacsony szintű formattálás nem csak egy partícióra, hanem a merevlemez teljes tárolásra alkalmas területére vonatkozik. Az alacsony szintű formattálást a winchester gyártók végzik, ugyanis nem megfelelő végrehajtása könnyen tönkretehetné a teljes merevlemezt. Az alacsony szintű formattálás után a merevlemez még nem alkalmas adatok (fájlok) tárolására; ehhez még magas szintű formattálás is szükséges. A magas szintű formattálás (high-level formatting) vagy logikai formattálás (logical formatting) az a folyamat, melynek során az operációs rendszer felkészít egy partíciót egy bizonyos fájlrendszer használatára. A logikai formattálás a partíción létrehozza a boot szektort, a fájlszervezési táblát (például
