LAB 1.2 CMOS SET UP UTILITY

Objective:

To know what are the things to be done in CMOS

To change and return CMOS values

To set up CMOS

 

Materials required:

A working station system unit with an internet access.

CMOS SET UP UTILITYLab preparation:

Check to see if the computer is working and checked the CMOS settings if it is in its default values. If not set it default to avoid errors in doing this laboratory experiment.

Activity Background:

In the previous laboratory report you got to know all about CMOS as to where it is applied and its functions. Now, all the things we learned from the very start of this laboratory report we will see why CMOS is very important and how to set up our CMOS properly so that we will be able to navigate and/or change values in the CMOS properly without causing much of a problem.

 The floppy drive, hard drive, and the date/time settings can be changed using the standard CMOS setup. Modern computers provide extra CMOS settings for memory management, password and booting options, error handling, and power management.

Instruction:

1. Computers manufactured in the last few years allow you to enter the BIOS setup using one of the five keys shown below during the boot process, F1, F2, F10, DEL, ESC.

2. Once in the Set up already, check for the CMOS settings available or the setting options that appeared on your screen.

3. Check to see if the CMOS is password protected.

4. Change the CMOS values you see.

5. Change some features in the CMOS utility set up.

6. Change the time and date.

7. Then run the setup.

CMOS SET UP UTILITY

Guide questions:

1. What are the settings available?

2. What happen after you run the setup?

3. What happen after you change the time and date?

Review questions:

4. What is the time and date that you set too?

5. Why are there errors when we change the time and date in CMOS?

6. How to remove if the CMOS is password protected?

7. What effects/cause when you change the CMOS values?

8. What is the difference between CMOS and BIOS?

LAB 1.3 CRITICAL THINKING- CMOS TROUBLESHOOTING

Objective:

Cultivate the ability to find and solve problems in an orderly manner.

Learn about the effects of changing settings on CMOS

Simulate a possible real-life problem that may occur to users and solve it by the techniques learned in previous laboratories

 

Materials Required:

Two working computers with the needed peripherals

Pens and paper

Two groups

Reference materials

Timer and Prizes

CRITICAL THINKING-CMOS TROUBLESHOOTING

Lab Preparation:

Before starting, check first if the computer is properly working, and no other problems can be found.

The BIOS menu should be restored to default settings to ensure the fairness for both groups.

 

Activity Background:

From previous activities, you have learned how to troubleshoot common problems that occur because of improper changes to the BIOS settings. Problems occurring from accidental changes to the BIOS is very common since most people will accidentally access this menu and sometimes change the values without the proper knowledge of what will happen if these settings are tampered with. Yes, you could just restore the BIOS to default settings to fix it, but sometimes the user actually has custom settings and by restoring it to default settings, these custom changes will also be reverted, and the user will need to change those back again. As a Computer Engineer, we must be able to diagnose the problems that will occur if these changes are made, and what should be done to fix them.

Procedures: Exchange computers with another group and go to the BIOS menu of their computer. Change two

settings that will make the computer not boot up properly. Write your changes on a piece of paper and give it to the professor.

Prepare some pen and paper to record your findings and return to your own stations, start troubleshooting the computer with your members. Restoring to default settings is not allowed.

QUESTIONS FOR GATHERING DATA

1. What did you see when you first booted up?

2. Without going to the BIOS menu, what do you think was changed?

3. After checking the BIOS menu, what did you find that was changed. Was it the same as your previous hypothesis?

4. Were there any more changes that you were not able to spot? If yes, what did you do to fix the problem? You may use any reference material given to you to help you in troubleshooting the computer. If you

are done, say so and the professor will check if all the changes made to your computer are returned to their previous settings.

The first three groups to fix their computers will be given prizes to compensate for their victory. The findings report should be stored because it will be submitted along with the other paper works done.

CRITICAL THINKING-CMOS TROUBLESHOOTING

Review Questions:

1. What were the changes you did to the other computer?

2. In your opinion, were the changes did to your computer hard to fix?

3. What were the steps that you took to find the problem of your computer?

4. If you were to repeat the activity, do you think that you will be able to troubleshoot the computer faster and more efficiently?

5. If you were not given any reference materials, do you think that you will be able to fix the problem?

BIOS FUNCTIONS AND UPGRADING BIOS

UPGRADIONG BIOS:

Before updating a BIOS, It is essential to Backup all important files in the system and most especially the BIOS configurations. 

1. Identify the make and model of the Motherboard, either by looking at the mainboard's manual or by looking at the board itself. What is the model of the system's motherboard?

2. Also on the main board, Note down the revision number of the main board as it may require different BIOS file to previous revisions. What is the revision number?

3. Find out the current BIOS version by holding the windows key+R to bring up the run command prompt and type in msinfo32. In the system information window which appears, select system summary on the left and look for the BIOS Version. What is the Current BIOS version indicated?

4. Head to the motherboard's manufacturer website and look for a support link. Search for the model by using list of available downloads and Download the latest BIOS file. What is the latest version of the BIOS your mainboard supports?

5. Make a bootable USB drive by using a utility such as Rufus or Unetbootin and you would need an ISO image as well, and FreeDOS. Once you connect a USB drive onto the system and run one of these applications, copy all necessary BIOS and Update utility files that you had downloaded from the manufacturer’s website. Give at least one link from the 2 applications needed to make a bootable USB drive.
