LAB 6 Computer Hardware

DO NOT WRITE ON THESE SHEETS. Use your own paper. You are to turn in Section III at the end of the lab.

I. During the Lecture/demonstration of Mike Wilson, you should understand each of the following:



 Expansion Slots


 BUS architecture EISA, VESA, PCI






 Data bus 16/32 bit




 Math coprocessor


 DX vs DX processor


 Intel: 8088, 8086, 80286, 80386, 80486, Pentium, Pentium II, Pentium MMX


 Motorola: 68000, 68020, 68030, 68040, 601,603, 604,750




 Bus mouse port (Serial Mouse port)


 Parallel port, Serial Port (Number of pins ,kind of pins)


 Video ports (number of pins)


 Power supply


 SCSI interface




 Memory Slots


 SIMMs ( parity, non parity) Speed, 30 pin ,72 pin


III. Turn in at the end of the Lab (on your own paper) the results of your findings of the following

Currently, you need to only set the appropriate jumpers and the system will "auto detect" what type of hard drive you have and the system will set up the appropriate parameters in the CMOS automatically. However in the older systems with smaller drives, the user had to manually set the CMOS parameters. To find the parameters for the on Seagate ST-225 hard drive, do the following.

1. Open the hard drive ST-225 and write down how many heads you think the drive has_____

2. Open Netscape and go to the web site

3. Select DRIVES in the left frame

4. Select SEGATE

5. Find this MFM coded Seagate ST-225 and scroll down to see the old CMOS settings that had to be entered before the system would recognize your hard drive. Enter the following parameters

a. Number of heads ______

b. Number of sectors per drive ______

c. Number of tracks per drive _______

d. Number of sectors per track _______ (you must calculate this value)

e. Total capacity in MB_____

For more on partitioning your hard drive, check the site

What is the probable wasted space if you had a partition of 1.6 GB?______

For your information: Mother board reviews. Some things that you should consider in mother board replacements.


III. Use one of the old systems to do the following

A. Remove and replace one SIMM

B. Remove and replace one interface card.

C. Remove and replace the hard drive or the floppy drive
