IBM – Gates and Windows, Mac wars – show 1984 video


Review safety especially ESD and processors – Remove Power


Internal components


Motherboard

Form, Fit and function

AT, ATX, NLX, MicroATX

Components location

CPU, Clock crystal, bus slots, P1 P8, P9

Jumpers and switches

Motherboard books

Power Supply – AT ATX

Testing voltages – fan running – connectors

Computer Math


Binary

Hex

Decimal

Boolean – See attached sheet

ASCII – see attached sheet


Boot Process

Hard (cold) boot versus soft (warm) boot

BIOS is in control when boot process begins

Turns control over to the OS


Steps in boot process


BIOS runs power-on self test (POST) and assigns resources



ROM BIOS startup program searches for and loads an OS




OS configures the system and completes its own loading




In Windows 9X OC


Files necessary to boot to command prompt

Io.sys

Msdos.sys

Command.com

To customize 16-bit portion of load process

Autoexec.bat

Config.sys




DOS


File structure – tree – naming convention (8.3)


Commands – internal (located in path) vs. external (located outside of path)

Dir, Attrib, MKDIR or MD, CD, RD, Path, Prompt, Erase, delete, edit, version, Format, fdisk, volume name, copy, xcopy, chkdsk, diskcopy, label, undelete, unformat, recover, tree, deltree, edlin, compare, backup, restore, replace, expand, more, page, find, echo, mem, print, control C, Control P (echoes to printer - logging), redirecting

Switches, ? help, command syntax, batch files


Wild cards

Question mark (?)

Wildcard for one character

Asterisk (*)

Wildcard for more than one character
