  1. Installing a Linux System Unit objectives • Install Fedora Core 2 • Describe types of hardware devices and their configuration • Obtain the necessary information about hardware and software to install Linux

  2. Topic A • Topic A: Installing Linux • Topic B: Understanding hardware • Topic C: Gathering pre-installation information

  3. Installation methods • Network installations • FTP server • Web server • NFS server • Hard disk • CD-ROM

  4. Installation procedure • Start installation • Choose language, keyboard, mouse • Specify options • Partition hard disk • Configure boot loader • Configure network and firewall • Choose system language and time • Set root password continued

  5. Installation procedure continued • Select packages • Create user account • Configure video

  6. Beginning the installation

  7. Choosing the installation type

  8. Activity A-1 Starting the installation

  9. Common partitions

  10. Virtual memory • Supplements physical memory • Should be twice the size of the RAM

  11. Adding a partition

  12. Activity A-2 Creating hard disk partitions

  13. Configuring the boot loader • Boot loader • Started by the BIOS after POST • Loads Linux into memory • Can also boot other operating systems • LInux LOader (LILO) • GRand Unified Bootloader (GRUB) continued

  14. Configuring the boot loader, continued

  15. Configuring the network

  16. Activity A-3 Configuring the boot loader, network, and firewall

  17. Selecting a time zone

  18. Activity A-4 Choosing system languageand time zone

  19. Activity A-5 Setting the root password

  20. Selecting packages

  21. Activity A-6 Selecting and installing packages

  22. Setting date and time

  23. Creating a user account

  24. Activity A-7 Completing the installation

  25. Topic B • Topic A: Installing Linux • Topic B: Understanding hardware • Topic C: Gathering pre-installation information

  26. Major components of a PC • Central processing unit (CPU) • Physical memory • Disk drive • Mainboard & peripheral components • Video adapter card • Keyboard & mouse

  27. Functions of CPUs • Manipulate data • Perform arithmetical computations • Direct the functions of other hardware devices

  28. CPUs: cache • Level 1 (L1) • Cache stored in the processor itself • Level 2 (L2) • A separate computer chip that is connected to the processor via a high speed link

  29. CPUs: Multiple processors • Symmetric Multi-Processing (SMP) • Each processor shares tasks and memory space • ASymmetric Multi-Processing (ASMP) • Each processor is given a certain role or set of tasks to complete independent of the other processors

  30. Exercise B-1 Discussing central processing units

  31. Physical memory • Storage area for information • Two main categories • Random Access Memory (RAM) • Read Only Memory (ROM)

  32. RAM types • Dynamic RAM (DRAM) • Single In-line Memory Modules (SIMM) • Dual In-line Memory Modules (DIMM) • Static RAM (SRAM)

  33. Read Only Memory (ROM) • ROM is physical memory that can be read, but not written to • Used to store the firmware used by hardware devices

  34. ROM variants • Programmable Read Only Memory (PROM) • Erasable Programmable Read Only Memory (EPROM) • Complimentary Metal-Oxide Semiconductor • Electronically Erasable Programmable Read Only Memory (EEPROM)

  35. Exercise B-2 Understanding physical memory

  36. Disk drive devices • Hard disk • CD-ROM • Floppy disk

  37. HDD controller cards • Integrated Drive Electronics (IDE) • Also known as Advanced Technology Attachment (ATA) • Small Computer System Interface (SCSI)

  38. IDE HDD configurations

  39. Partitions • Partitions • Divide up a hard disk into smaller areas • Filesystems • A format that holds data within the partitions continued

  40. Partitions, continued • Primary partitions • Divisions of a drive’s space • Extended partitions • A partition that can be further subdivided into logical drives • Master Boot Record (MBR) • Area outside of a partition

  41. Partitioning scheme: primary master

  42. Other information storage devices • Removable media • Can be removed and transferred to other machines • Floppy disks • Zip disks

  43. Activity B-3 Using disk drives

  44. Busses • Bus • Pathway from one hardware device to another • Types • Industry Standard Architecture (ISA) • Peripheral Component Interconnect (PCI) • Accelerated Graphics Port (AGP)

  45. Mainboard board components

  46. Peripheral components • PS/2 ports • Connects keyboards and mice • Serial ports • Connects many different peripherals • Also called a COM port • Parallel port • Connects printers • Also called a LPT port

  47. USB and Firewire • Universal Serial Bus (USB) port • Used keyboards mice, printers, scanners, cameras, etc. • Can be attached while the computer is running • Called hot-swappable • Firewire (IEEE1394) • Hot-swappable variant of USB

  48. PCMCIA ports • Personal Computer Memory Card International Association (PCMCIA) • Supports peripherals built into small, enclosed cards • Hot-swappable

  49. Device settings • Interrupt Request Line (IRQ) • Specifies a unique channel from a device to the CPU • Input/Output (IO) address • Small working area of RAM where the CPU can pass information to and receive information from a device • Plug-and-Play (PnP) • OS and peripheral devices that can automatically assign the correct IRQ, I/O address, and DMA settings without any user intervention

  50. Exercise B-4 Discussing mainboards and peripheral components
