    3. The PC has just completed a POST check after successfully installing a second IDE device on IDE 1 with Windows 98 installed on IDE 0. Which of the following would be the most accurate in regards to the location of the first set of startup instructions?
    Once POST has been completed the CPU seeks the MBR (master boot record).
    Since the PC has completed POST, the first set of instructions would be found at the root of drive C, which in turn will start Windows98.
    Once POST is complete, ROM BIOS is assigned the responsibility of seeking the MBR which holds the first set of startup instructions.
    The floppy disk will hold the first set of instructions, and if it is unavailable then the root of drive C:\> will be sought.
    Answer/Explanation
  • Once POST is complete, ROM BIOS is assigned the responsibility of seeking the MBR which holds the first set of startup instructions.

    On a PC with a single operating system then the MBR (Mater boot record) will load the appropriate files to start the operating system.
    If the PC is capable of booting to multiple operating systems then the ROM BIOS will go to the MBR which will then point to the partition table for the startup menu, where the user can choose the operating system to boot to.
    The CPU does not have any brains, and thus does not have the responsibility of locating the MBR.
    Regardless of the device that is being booted the first set of startup instructions will always come from ROM BIOS.
    The drive root (c:\>) holds the information that is required to load the operating system, it does not hold the MBR.

    4. The earlier method of recognizing hard drives was using CHS which gave us the 504MB drive limitation, which was not a problem in the earlier days of smaller operating systems and application programs. As time had passed the need for larger drives became obviously apparent and LBA was introduced along with INT 13 to offer support to the ever growing size of hard drives. Which of the following operating systems was the first to incorporate FAT 32 as a means to provide hard drive access?
    Windows 98 with service pack 1.1
    Windows 95 with service pack 2.0
    Windows 98 SE OEM version.
    Windows 95 OSR/2.
    Answer/Explanation
  • Windows 95 OSR/2.

    Converting FAT16 to FAT32 has many more advantages over FAT16, but it is not compatible with Windows NT 4.0.
    FAT 32 may be found on Windows 95b, Win 98 SE and ME. File level security cannot be implemented on FAT 32. It offers folder level security only.
    You can convert FAT16 to FAT32 without losing your data, but you cannot convert FAT32 to FAT16 without reformatting and losing all your data.

    5. Which of the following two items should be checked if a client reports that their system performance has dropped significantly after they have installed a new application?
    Check the Scan REG log.
    Check the free space on the hard drive.
    Check for available system RAM.
    Check the speed rating of RAM chips.
    Check the access time and rotation speed of hard drive.
    Answer/Explanation
  • Check the free space on the hard drive.
  • Check for available system RAM.

    Since the system is reported to have slowed after the installation of a new application it could have consumed available disk space that was to be used as a swap file. Also the program may required more RAM.

    6. Which of the following errors will occur if SCSI hard drive translation is disabled, and INT-13 extensions are disabled in the SCSI BIOS on the SCSI controller, during the install phase of Windows 2000?
    Hard drive translation and SCSI INT-13 extensions do not apply to the install phase of Windows 2000.
    The system partition cannot be used to boot from because cylinder translation beyond the 1024 cylinder limit is unavailable.
    There will not be any errors because the system board BIOS INT-13 extensions will be available.
    The boot partition cannot be used to boot from because cylinder translation beyond the 1024 limit are unavailable.
    Answer/Explanation
  • The system partition cannot be used to boot from because cylinder translation beyond the 1024 cylinder limit is unavailable.

    Windows NT4, W2K and XP boot from the system partition, and have system files located on the boot partition. Windows NT require that cylinders beyond cylinder 1024 are available for installation.

    7. A client calls and tells you and states that while he was upgrading to Windows 98 the system files could not be updated and the system stopped responding. Which of the following should be disabled in order to install a system upgrade?
    Disable the fast boot option in system BIOS.
    Confirm that the BIOS is PnP (Plug and Play, and if not have it upgraded.
    Disable the antivirus feature in the system BIOS.
    Disable Drive compression.
    Answer/Explanation
  • Disable the antivirus feature in the system BIOS.

    The system BIOS, antivirus feature prevents the MBR (Master Boot Record) from being changed, since this would possible be a boot virus. Thus this needs to be disabled to upgrade or install any Microsoft® operating system. None of the remaining options will prevent an upgrade of a Microsoft® operating system.

    8. After installing a hard drive, and ensuring that the jumpers are correct, you format the hard drive using the Fdisk program. With the following command [a:\>sys c:] you transfer the system files to the C: drive. In which of the following locations will these files be stored?
    System files are stored in the FAT after the drive has been formatted.
    System files are stored in the Root after the drive has been formatted.
    System files are stored in the MBR after the drive has been formatted.
    System files are stored in the Root of the folder of the operating system.
    Answer/Explanation
  • System files are stored in the MBR after the drive has been formatted.

    If the PC is configured as a dual boot then the MBR will point to the partition table where a menu will open for the user to then choose which operating system to boot to.
    NTFS (New technology file system) is the file system used by Microsoft Windows NT4, Windows 2000, and XP.
    The FAT (File allocation table) is used as a table of contents, to identify where on the hard drive files and folders are located when using FAT16 or FAT32.
    An example of the root of a drive would be C:\> which is where the operating system, folders and files are located.
    Keep in mind that the system files cannot be copied to the hard drive, they must be written to the MBR either through the installation of an operating system, or through the ‘sys’ command from a command prompt.

    9. What of the files listed below are necessary to boot Windows 9X to at least a DOS prompt?
    MSDOS.SYS, AUTOEXEC.BAT, CONFIG.SYS
    IO.SYS, MSDOS.SYS, AUTOEXEC.BAT
    IO.SYS, MSDOS.SYS, COMMAND.COM
    IO.SYS, CONFIG.SYS, AUTOEXEC.BAT
    Answer/Explanation
  • IO.SYS, MSDOS.SYS, COMMAND.COM

    Keep in mind that the system files cannot be copied to the hard drive, they must be written to the MBR either through the installation of an operating system, or through the ‘sys’ command from a command prompt.
    Autoexec.bat and config.sys are not required to boot DOS. The autoexec.bat file is used to provide a path statement for programs and the config.sys is sued to load device drivers.

    10. It appears that the MBR is corrupt and you are unable to get the operating system to load with Windows 98 SE. Which of the following commands could be typed at a command prompt to restore a damaged registry?
    From a command line in real mode use the scanreg /fix command.
    From a command line in protected mode use the fdisk /scanreg command.
    From a command line in protected mode use the fdisk /mbr command.
    From a command line in real mode use the scanreg /restore command
    Answer/Explanation
  • From a command line in real mode use the scanreg /restore command

    This works well if the customer has not attempted multiple boots after the failed boot, since there are only 5 boots kept in this location by default.
    Start the computer and immediately press the F8 key. We only want io.sys to get loaded and not msdos.sys.
    A start menu screen will appear with an option to boot to a command line only. By choosing this option we will be in real mode. At the command prompt type in scanreg /restore so your screen will look as follows;
    C:\>scanreg /restore
    Press the enter key.
    A dialog box will open offering you the choice of 5 boots, successful and unsuccessful. Select a successful boot.
    The registry will be restored to that particular date, and no data will be lost, but it maybe possible that a program will need to be reloaded.
    A hard drive is not required for a PC to pass POST. For a successful POST, RAM, keyboard, speaker, and a CPU are required. Technically a CRT is not required because we could hear the single beep to indicate that POST was successful.
    A bad hard drive controller will offer a 17xx error.
    An incorrect setting in CMOS will not prevent a successful POST; it could possibly prevent a component from working due to a hardware conflict.
