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? _____________
