Day 33 Agenda

    1 . Discuss Chapter 8 (hard disk) concepts:

        Number of partitions that can be created on a physical disk

        The partitioning tools provided with MS DOS and Windows 9.x
         allow you to create a maximum of ___ primary partition(s) and
         ____ extended partition(s) on a physical hard disk.

         If you create an extended partition on a physical disk, you can use
         it to create a maximum of 26 __________  labeled C through Z.
         If the hard disk has one primary partition, and the computer has
          one CD-ROM drive, the extended partition can contain a maximum

          of  ___     _______ drives (assuming the primary partition is not hidden
          by third-party software and the CD-ROM drive is not disabled).

         - - -

         If you use partitioning tools from Windows XP/2000 or NT4, you
         can create a maximum of ___ partitions on a disk  Only __ partition(s)
         can be an extended partition.

         In most cases, Windows 9.x can recognize additional primary partitions
         created in the FAT16 or FAT32 format if you use partitioning tools from other
         operating systems. The active partition becomes drive C, and other primary
         partitions in an OS-compatible format are listed as D, E, or F.
         MS DOS can't do this. If there is more than one primary partition on the disk,

        only the active partition will be accessible.

         Practical Application of this Principle

    Suppose you create a dual-boot system by installing Windows 98
    on a primary FAT32 partition that takes up half of a physical disk.
    Then you install Windows 2000 by creating a second primary FAT 32
    partition that takes up the rest of the disk (The Windows 2000
    installation CD will allow you to do this.)

    If both partitions are FAT32, you should be able to switch the active
    partition by using either FDISK or the Windows XP/2000 Disk Manager.

    Which operating system will start up and appear as drive C if the first (Win9.x)

    partition is set active? (.)   _____.     Will you be able to view the W2K OS

    and its files listed on a partition labeled drive D? _____.

    Which operating system will start up and appear as drive C if the
    second (W2K) partition is set active? _____ Will you be able to

    view the Win 9.x OS and its files listed on a partition labeled drive D? _____.

    Suppose you press F8, with the Win 9.x partition set active, and boot
    the computer to an MS-DOS prompt.  Will you be able to view the W2K

    OS and its files on a partition labeled drive D? ________

    - - -

    The operating system may impose additional limitations on storage size for IDE
    disk partitions (besides the ones imposed by the BIOS and IDE controller).

       Are the FAT16 limitations under Windows XP/2000 the same as
        under Windows 9.x? _____ 

        Are the FAT32 limitations under Windows 2000/XP the same as
        under Windows 9.x? ____

       With Service Pack 4 or higher installed NTFS under Windows NT4 has
        the same size limitation as under Windows 2000/XP. See this link
        for more information.

    Serial Port Minilab

    Go into Windows 98 Device Manager. Examine settings for your computer's serial port(s),
    then remove them and reboot the machine. The ports should be redetected automatically.

    Remove both serial ports from Device Manager again. Reboot, go into
    the machine's CMOS and disable the second serial port. Change the
    settings on the first serial port to use IRQ3 and Address 2F8. Save the settings
    and reboot into Windows 98.

    Examine Device Manager under the Ports section. What do you see? _______________



    Delete the serial port entry from Device Manager, reboot the computer,
    go into the CMOS settings and restore the default settings for COM1 and

    COM2. (COM 1 IRQ ____, Address _____, COM2 IRQ ____, Address ____

    Reboot into Windows 98 and check Device Manager. Both serial ports should be
    redetected automatically again.   See if you can create an IRQ or Address conflict by
    going to the resources for the second serial port and changing the automatic settings.

    If you successfully create a resource conflict, how can you resolve it? _____________

    Parallel Ports

    Read A+ in Depth p. 411-414, Do Meyers Lab 19.1 on parallel ports on Meyers p.212

    The three common settings/types for parallel ports are   ____,   _____,    _____

    Video Card installation (See A+ in Depth, Ch. 10, p. 432 - 438)
    Device Manager and remove the listing for your Windows 98 Display Adapter
    Reboot the computer and see whether you can reinstall the driver. (It may be detected automatically)


    Study for midterm on Thursday, which will include material through Andrews, Ch. 8 on hard drives.

    Work on research projects

    Read A+ in Depth Chapter 10, and write out answers to
    questions 1-21 on p. 449-451
