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
Topic A • Topic A: Installing Linux • Topic B: Understanding hardware • Topic C: Gathering pre-installation information
Installation methods • Network installations • FTP server • Web server • NFS server • Hard disk • CD-ROM
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
Installation procedure continued • Select packages • Create user account • Configure video
Activity A-1 Starting the installation
Virtual memory • Supplements physical memory • Should be twice the size of the RAM
Activity A-2 Creating hard disk partitions
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
Activity A-3 Configuring the boot loader, network, and firewall
Activity A-4 Choosing system languageand time zone
Activity A-5 Setting the root password
Activity A-6 Selecting and installing packages
Activity A-7 Completing the installation
Topic B • Topic A: Installing Linux • Topic B: Understanding hardware • Topic C: Gathering pre-installation information
Major components of a PC • Central processing unit (CPU) • Physical memory • Disk drive • Mainboard & peripheral components • Video adapter card • Keyboard & mouse
Functions of CPUs • Manipulate data • Perform arithmetical computations • Direct the functions of other hardware devices
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
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
Exercise B-1 Discussing central processing units
Physical memory • Storage area for information • Two main categories • Random Access Memory (RAM) • Read Only Memory (ROM)
RAM types • Dynamic RAM (DRAM) • Single In-line Memory Modules (SIMM) • Dual In-line Memory Modules (DIMM) • Static RAM (SRAM)
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
ROM variants • Programmable Read Only Memory (PROM) • Erasable Programmable Read Only Memory (EPROM) • Complimentary Metal-Oxide Semiconductor • Electronically Erasable Programmable Read Only Memory (EEPROM)
Exercise B-2 Understanding physical memory
Disk drive devices • Hard disk • CD-ROM • Floppy disk
HDD controller cards • Integrated Drive Electronics (IDE) • Also known as Advanced Technology Attachment (ATA) • Small Computer System Interface (SCSI)
Partitions • Partitions • Divide up a hard disk into smaller areas • Filesystems • A format that holds data within the partitions continued
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
Other information storage devices • Removable media • Can be removed and transferred to other machines • Floppy disks • Zip disks
Activity B-3 Using disk drives
Busses • Bus • Pathway from one hardware device to another • Types • Industry Standard Architecture (ISA) • Peripheral Component Interconnect (PCI) • Accelerated Graphics Port (AGP)
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
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
PCMCIA ports • Personal Computer Memory Card International Association (PCMCIA) • Supports peripherals built into small, enclosed cards • Hot-swappable
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
