3. Lab Work
Finish serial port lab from day 33, and Meyers Lab 19.1
Try changing parallel port settings from Normal (SPP) to ECP in
the CMOS, boot into Windows and see if the driver changes
automatically. If not, you can install the ECP driver, manually?
Does the ECP driver under Windows 98 use an IRQ? ____
Video Card installation (See A+ in Depth, Ch. 10, p. 432 - 438)
Open 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
Go into the Display Properties through Control Panel (or right-click on the Desktop). On the
Settings Tab, identify the color depth and Screen area used by your display. Screen area,
also called ____________ is measured by the number of spots (or _______) in each
horizontal line of the screen display, multiplied by the number of vertical lines. See if you
can shift the screen resolution between 640x480 and 800x600. (You may need to download
and install a driver for the video card to do this, if the system is using the default Standard
VGA driver.) Also see if you can shift the color depth between 256 and High-Color and
compare the screen results by looking at a color photograph on the Internet.
The refresh rate for your computer is the number of times per second an electronic beam
fills the screen from top to bottom. Go into the Advanced Settings and determine the
Vertical Refresh Rate for your system. (You'll probably find this on the Monitors tab.)
Work on research projects. We want to start doing these 10-minute presentations
before Thanksgiving. They don't have to be giant projects. If you have a topic,
make a list of important points you want to share with the class and how many minutes
to spend on each point. We'll talk about this next week, so we can review your gameplans
for your presentations.
Have answers to Chapter 10, questions 1-21 ready for inspection on Tuesday. We'll
probably have a take home quiz on Chapter 10 that you can work on next week.
Read A+ in Depth Chapter 11, and take notes. Focus on p. 454 to 461 on installing a
sound card, which we'll do in class.
Important concepts in Chapter 11 to take notes on:
Installing sound cards
Identify CDROM file systems
How CDROMS and DVDs interface with the motherboard
Different technologies for burning CDs and DVDs
How Tape Drives Work
Different types of removable drives (ZIP, JAZ)
How to troubleshoot CDROM, DVD, Tape Drives and Removable Drives.
