Thursday

November 02, 1999


Create dos boot disk

Create DOS Boot Disk

  • At C: prompt Format A: /S

  • This will format the disk and copy minimum start-up files

  • You can also copy the three required files


Dos start up disk

Dos Start-up Disk

  • Need Three Files

    • IO.SYS

    • MSDOS.SYS

    • COMMAND.COM

    • Only Command.com will show when you run dir


Attrib

ATTRIB

  • Shows all files, hidden and non-hidden

  • Attrib /?

  • List the possible switches


Io sys

IO.SYS

  • Also, IBMBIO.COM

  • Extends ROM-BIOS Chip

  • Handle the basic input and output devices

  • Contains the low level programs that interact directly with devices on the system


Msdos sys

MSDOS.SYS

Handles disk routines

Reads input from keyboard

Writes to the monitor

Opens and closes files

Handles directories

Deletes files

Contains the DOS disk and device handling programs


Command com

COMMAND.COM

  • The part of the operating system that receives and executes operating system commands.

  • Dir, Del, Rename, Copy

  • Type, Cls, Date, Time


Drvspace bin

DRVSPACE.BIN

  • May be included and used when a drive is compressed.


Other files to include

Other Files to Include

  • Format.com*Format.com

  • Fdisk.exeScan.exe

  • Mscdex.exe*Config.sys

  • Xcopy.exeAutoexec.bat

  • Deltree.exeEdit.com*

  • Attrib.exeDefrag.exe

  • Diskcopy.exeMem.exe

  • See Page 1414


Cd rom support method one

CD-ROM Support Method One

  • Make a DOS start-up disk

    • Format a: /s

  • Open the Autoexec.bat and the Config.sys on the C drive and look for CD-ROM Drivers


Cnet 1101

Autoexec.bat

  • c:\windows\COMMAND\MSCDEX.EXE /D:MSCD003 /M:12 /L:G /V

  • @C:\PROGRA~1\NORTON~1\NORTON~2\NAVDX.EXE /Startup

  • SET CLASSPATH=C:\Program Files\PhotoDeluxe 2.0\AdobeConnectables

  • @ECHO OFF

  • SET BLASTER=A220 I5 D1 T4

  • PATH C:\PROGRA~1\MICROS~2\OFFICE;c:\windows;c:\windows\COMMAND;C:\IBMTOOLS;c:\program~1\office97\office

  • LH c:\windows\COMMAND\DOSKEY

  • CWBMIX.EXE /t=1,1

  • SET DMIDIR=C:\DMI


Cnet 1101

Config.sys

  • LASTDRIVE=M

  • DEVICE=C:\windows\HIMEM.SYS /testmem:off

  • FILES=40

  • BUFFERS=50

  • DOS=HIGH,UMB

  • Rem TShoot: DEVICEHIGH=C:\WINDOWS\COMMAND\IBMIDECD.SYS

  • rem DEVICEHIGH=C:\WINDOWS\COMMAND\IBMIDECD.SYS /D:IBMCD001

  • device=c:\windows\cwbinit.exe /A /M

  • DEVICE=\DEV\HIT-DVD.SYS /D:MSCD003


Cd rom support

CD-ROM Support

  • Copy AUTOEXEC.BAT To A:

  • Copy CONFIG.SYS A:

  • REM out all lines except MSCDEX.EXE and CD-ROM Driver

  • Copy MSCDEX.EXE and Drive to A:

  • MSCDEX.EXE is an extension that allows CD-ROM to work in DOS. See page 865


Autoexec bat

Autoexec.bat

  • C:\windows\command\mscdex.exe /d:mscd003 /l:g

  • Change to

    • MSCDEX.EXE /d:mscd003 /L:G


Config sys

Config.sys

Device=C:\dev\ht-DVD.sys /d:mscd003

Change to

Device=ht-dvd.sys /d:mscd003


Generic cd rom driver method two

Generic CD-ROM DriverMethod Two

  • Format disk

    • Format a: /s

  • Create Autoexec.bat and Config.sys on the A: Drive

  • Copy MSCDEX.EXE to A:


Cnet 1101

  • Download OAKCDROM.SYS

  • www.halcyon.com/cerelli/floppies.htm

    • Copy to A: Drive

  • In Config.sys

    • Device=oakcdrom.sys /d:mscd001

  • In autoexec.bat

    • Mscdex.exe /d:mscd001 /l:g

    • Make sure mscdex.exe and oakcdrom.sys are on floppy
