The Practical Portion of This Book Table of Contents Finally! A Chapter on computers, rather than theories and training. The information in this chapter is survival stuff - it includes short tables of the most often sought after information for fixing computers. It was so hastily compiled that anyone could write a much better guide than this one. Hence, I have left space in the tables for you expand them, making this your own book. Job Organization IT/Computer volunteers will need to work at more than one place in order to train people in a sustainable way. In order to make your job easier, we have tried to compile a list of potential workplaces for each volunteer. One volunteer will cover offices in each of the different zones in the map below. Keep in mind that this is only a list of possible places, and that no one could work at them all. Start with one place, and add other good workplaces until you have three to five good places. Likewise, you will invariably find more places to work at than just those on this (incomplete and most likely outdated) list. Each IT/Computer volunteer should be encouraged to live within his or her zone, but not necessarily in the same place as his or her immediate predecessor. For example, a LRD/NBD volunteer based out of Farafenni could be replaced by one based out of Mansa Konko. This will enable projects to continue, but lessen the temptation for area offices to see you as a permanent staff person. Locations in the periphery of your zone could be visited once each quarter, or you could invite people from these place to a workshop in a central place. Volunteers in larger zones may need to organize Workshops in order to reach everybody in the two years of service. Upon arriving at your site, take time to assess the needs of the community before getting locked into projects which might not be the most effective use of your time. The math/science portion of your technical training should help you in working with schools and identifying the best workplaces. You will probably need to change projects in your second year, but remember to continue to keep an open dialogue with former workplaces. For reference purposes, Peace Corps' official description of the job for which you interviewed with your recruiter follows the work maps. Work Zones for IT/Computer PCVs Western Gambia

Hardware: Motherboards To Reset CMOS data, you can first try changing the jumper nearest the motherboard clock battery. It should have only two positions: (For 3 pins: 1-2 or 2-3; For 2 pins: Jumper is Closed and Open) To clear CMOS, turn the computer on for 5 seconds after changing the correct jumper then change it back. The computer should not have any more stored setup information (including passwords). If that doesn't work, try removing the battery.
Expansion Cards come in two and a half varieties. The pre-pentium computers have ISA slots, while newer computers have PCI slots. Some pentiums still have one or two ISA slots so older cards can be used. The "half" variety is the VESA-local bus slot, which you will see on a lot of 486 machines. VESA looks like the original ISA slot but with 2 more connections at the end, so that it hooks up to four different protrusions on an expansion card. A VESA slot can take an ISA card also.
If you need to connect the power supply to the motherboard, look for a 12 holed socket in the back corner near the keyboard jack a little like the picture to the left. Find two plugs on the power supply that fit it and connect them so that the four black wires are in the center, and not on the outside.A typical motherboard is shown below. Other parts of a motherboard include the CPU, memory banks (bank 1 and bank 0), BIOS chip, Keyboard controller chip, cache, and various jumpers. If there is something else important about motherboards not contained in this manual, fill it in the margin box here:
When connecting a hard drive to a computer, check the following:
Other important stuff about hard drives: Norton Disk Doctor: This DOS program might not fix your hard drive problems, but you can at least use it to identify the physical characteristics of your drive. It will list cylinders, heads, and sectors for you. Partitions: Every hard drive must have a partition, sort of a set of boundaries for each logical drive to occupy. On some computers, MASTER BOOT DISK FAILURE or NO ROM BIOS: SYSTEM HALTED are indications that the hard drive is possibly not partitioned. To partition a drive, boot with a floppy and run FDISK. Deleting a partition destroys all data on the logical drive corresponding to that partition. The following is about partitioning from Hardwarecentral.com: Partitioning is one of the necessary steps to prepare a drive for use. It is the process of defining certain areas of the hard disk for the operating system to use. A volume is a section of the drive with a letter, like C: or D:. All hard drives must be partitioned, even if they will have only one partition. A partition program writes a master partition boot sector to cylinder 0, head 0, sector 1. The data in this sector defines the start and end locations of each of the other partitions. It also indicates which of these partitions is active, or bootable, thus telling the computer where to look for the operating system. DOS FDISK is the accepted program for partitioning. FDISK only shows two DOS partitions, the primary partition and the extended partition. The extended partition is divided into logical DOS volumes, each being a separate partition. The minimum partition size is one megabyte, due to the fact that FDISK in DOS 4.0 or later creates partitions based on numbers of MB. Partition size is usually limited to 2G. DOS versions earlier than 4.0 allow max partitions of 32 MB. Using the FAT32 system under DOS 7 and Windows 95 OSR2, max partition size is kicked up to 2 TB (2 TB = 2048 GB = 2,097,152 MB = 2,147,483,648 KB = 2,199,023,255,552 bytes). FDISK in DOS 5.0 or later is more powerful than most people know. There are several options available with the program that are undocumented in the DOS manuals. The bad news is that these commands are unavailable with Windows 95. Instead, you will have to purchase a third party program such as Norton Utilities. The most useful, in my opinion, is the "/MBR" parameter. This parameter tells FDISK to rewrite the Master Partition boot sector based on the partitions present on the drive without damaging the partitions on the drive. This is very useful when recovering from a virus that infects the boot sector of the drive. Use it by typing "FDISK /MBR" at the A: prompt. [You can in fact remove a virus from a hard drive without needing a virus killer disk using this command!] To back up the partition table onto a floppy diskette, type "MIRROR /PARTN". This uses the MIRROR program to copy the partition table into a file called PARTNSAV.FIL. This can then be stored on your system disk. To restore this partition info, type "UNFORMAT /PARTN". Format: If a partition is a set of boundaries, the format is the set of nice boxes to store all your files. After you partition a new, blank drive, you need to format it. To format a drive, boot with a floppy and run FORMAT. Note: Be aware that PCs now use old FAT16 and new FAT32 style disk formats. FAT32 makes the drive run faster but it is not compatible with older operating systems (including even Win95a, Win95.1111 (but Win95-OSR2 or Win95b work)). A 2.0gigabyte or larger disk will need FAT32 to be formatted in a single partition. Fat16 is slow and reliable: Every computer will be able to handle it. If you format a disk in FAT32 on a Pentium then move it to a 486, it probably won't work. How to Copy One Hard Drive to Another and Have it Boot: (From Hardwarecentral.com) The toughest part of upgrading to a new hard drive is the task of transferring all of your files and configurations. Yes, you can re-install Windows, re-install all of your programs, re-download all of your shareware, copy over all of your documents, and try to reconfigure it to the way you like it. But, why? There are much easier ways. This method involves the use of the common copy and paste routine of Windows. First, you must install the new drive. Install it as a slave to the old drive. 1.Partition and format the new drive just like normal. It must have the same number and size partitions as the old drive. 2.In Windows Explorer, choose View/Options. Select Show All Files. Deselect Hide MS-DOS file extensions for the file types that are registered. Click OK. 3.Choose Edit/Select All. All files and directories will be highlighted. Then click the copy icon in the toolbar. 4.Select the D: drive, or the letter of your new drive. Click the paste icon in the toolbar. The file transfer will take place, and may take a while depending on the size of the drive transferred. 5.Install the Windows system files to the new drive by going to the MS-DOS prompt and typing SYS D: at the C:> prompt. 6.Exit Windows and turn off the computer. 7.Swap the cable connectors going to the drives. Change the jumper settings to make the new drive master. Reboot. The system should work normally. If not, your old drive is still completely intact and can be used to get the system back in operation. Hardware: BIOS / CMOS BIOS Setup Keys: You will need to fill in this table yourself:
BIOS Beep Codes: [The following was copied from a tutorial on Hardwarecentral.com:] Introduction by David Risley Beep codes are the little beeps you hear out of the PC speaker whenever you turn the computer on. They are your computer's way of letting you know what's going on when the video signal is not working. These codes are built in to the BIOS of the PC. There is no official standard for these codes due to the many brands of BIOS that are out there, but the two main brands are Phoenix and American Megatrends, Inc. As a result, these beep code formats are the most common and will be covered here. If you don't know who made your BIOS, consult the manual of your motherboard. If you don't have a manual, simply take off the case and look. For information on identifying BIOS, click here. Once you find them, just see if it says "AMI" or "Phoenix." Once you have determined your BIOS make, consult the following to see what's wrong with your computer. AMI BIOS Beep Codes Normally, a computer with AMI BIOS doesn't bother with beeps. It will flash an error message right across your screen. It's when the video card isn't working or something rather serious goes wrong that your computer will start beeping.
Phoenix beep codes Phoenix beep codes are more detailed than are the AMI codes. It emits three sets of beeps. For example, 1 -pause- 3 -pause- 3. This is a 1-3-3 combination and each set of beeps is separated by a brief pause. You need to listen and count when your computer starts doing this. Reboot and recount if you have to.
cards, etc. They are IRQs, DMAs, and base memory addresses. An IRQ is basically a "stop and do this" message given to the CPU--an interrupt request. Each part must have its own IRQ line, so if you set two parts to the same line, your computer will crash. It will keep you from using the cards or just refuse to boot up until you take the parts out and resolve the conflict. This one concept is the basis of many heartaches involved with putting cards in. Base memory addresses are sometimes called I/O ports or port addresses. What are they? Well, CPUs respond to IRQs. CPUs can't respond down the same line that it is getting IRQs from. So, a different route is set up for the responses. It's a kind of go-between so that the CPU and the components can talk directly. Well, as usual, there are a certain amount of ports available. They usually look something like 02E8, or 03E8. Disk Utilities: SCANDISK / DEFRAG - The standard disk utilities. Use them. NDD - Norton Disk Doctor can identify hard drive problems. If you have NDD for Win95 it can save your hard drive. FIPS - This Linux disk utility for DOS will allow you to take one hard drive and split it into two without reformatting, something no other free program can do. MOVE - Moves files (a lot easier than copying sometimes) FDISK - used to partition hard drives. MSD - comes with DOS and tells you the addresses your computer is using. There are many Windows programs out there that do the same thing. Other: MEM - This DOS utility will tell you computer's RAM size. MEM /C will tell you TSRs DLLVIEW - this Windows utility will tell you all the DLLs that any program calls when it runs. Useful when trying to copy a program. GSETUP - generic BIOS setup program - for when you can't find that key to get into the BIOS. (downloadable from WebHQ - Chapter 4) TWEAKUI - Windows95 utility that tweaks the user interface in ways that Windows developers should have allowed. You can repair associations, drop the network login, and remove icons from the desktop. A must-add-on for your control panel. MagicDesktop - systray tool that will make all your desktop icons vanish. PKUNZIP - WinZip might be great, but this one is only 30K and fits on any disk. NETMEDIC - EXCELLENT!!! This Internet Watch program will record every call a computer makes. You can see the time spent online each month, sites visited, and relative efficiency of modem use in terms of percent idle. Given that Gamtel doesn't track or audit telephones, you need to yourself using this program. SYS - DOS utility to transfer the system files to a new drive or disk. You will need this to make a disk bootable. F8 - AccessBoot Menu If you need to boot to DOS instead of Win95, or start Win95 in SAFE MODE, press F8 exactly when it says "Starting Windows 95 " while booting. OS Size Considerations Windows 95 will require about 100MB, and Windows 98 takes 200-300MB. Win95 will run faster on most pentiums. Win98 will not run fast on a 486. Win95 installation (CAB) files take 28MB. Win98 CAB files take over 200MB. So don't install Win98 on less than 500MB. But you can install Win95 on as little as 116MB and have full functionality. Speeding Up Your Computer Go into your Device Manager every so often and delete old and unused drivers. When you install new hardware and replace old stuff, Windows 95 has a habit of leaving the old drivers there, and this invariably slows the entire system down. Make sure you don't delete the CD-ROM drivers or mouse drivers. To create a good system disk, follow the steps here: Here are some notes about the most important DOS commands: First, adding "/?" after any of these commands in DOS will explain them and give you syntax for using them. DIR - directory or list of files COPY [source file] [target location] - to copy files XCOPY - copy program that works faster and lets you copy subdirectories too "Dir /s /p" - lists files in directories and subdirectories. If you are in the root directory (C:\>) and you type "dir *.doc /s /p" it will list all the files on the hard drive that match your "*.doc" search. MOVE - moves files COPY CON [filename] - this will create a new text file and let you input the text one line at a time from DOS. Useful for batch files. Press F6 (or Ctrl-Z)when done to save. CD [dir name] - change directory MD [dir name] - make directory RD [dir name] - removes directory SYS [drive] - transfers system files to drive UNDELETE - restores deleted files in current directory. This is great, if it is installed. F3 - repeats the last DOS command CTRL-BREAK will cancel most DOS operations CTRL-ALT-DEL will reboot computers in DOS and bring up task manager in Windows. Copy [filename] prn - will sent a text file to the printer. Foxmail/Eudora/Outlook/Netscape - POP3 style email is absolutely necessary in The Gambia where every call costs money. These allow you to download mail, disconnect, then read it. Foxmail fits on a floppy disk for easy distribution, but Eudora is probably the easiest and most reliable. Teleport Pro - one of many "web spiders" - programs that allow you to make copies of often used websites on your hard drive. For example, you can use it to download the International Herald Tribute once a week, or Hardwarecentral.com tutorials all at once. Wintutor - this Win 3.1x tutorial is really basic, and has an introduction to the mouse. It comes with Win 3.1x. Jacks - freeware Win 3.1 game is good tool for mouse practice Mavis Beacon Teaches Typing - the definitive best Typing Tutor. Available on 2-3 floppy disks. MsWorks - is better than Word for introductory classes. It runs on any computer, fits on a floppy, has a simple appearance (so that students are confused by all the toolbars), and is fast. You can teach a year's worth of word processing concepts on this or even Wordpad. See Syllabus in the Appendix for details. Appendix I: Other Reading Materials Excerpts From: Peace Corps 2000 Project Status Reports Global Summary and Promising Practices: Information Technology Initiative February 2001 The Information Technology Training of Trainers (IT TOT) package was field tested in Kenya, Cape Verde, Belize, and Haiti in 2000, and will be ready for general distribution in early 2001. The IT TOT trains computer and internet literate Volunteers how to teach the skills that they have brought with them to others. Internet training was introduced to staff training for the first time to help staff use IT in their own work and better understand the value of IT in projects. And finally, Peace Corps recognized that community computer literacy centers, micro and small business web page design centers, and schoolbased IT learning centers assisted by Volunteers are multiplying around the world without support, but that the demand is enormous and growing. It is a fundamental truth that one cannot implement IT without hardware, software, and connectivity in addition to the transfer of skills. "We want to find ways to offer support and believe the numbers of those projects will be multiplied tenfold," stated Director Schneider. Peace Corps undertook the ePartnership Initiative in 2000, and the director challenged America's hightech corporations to assist Peace Corps' partners at the grassroots level to obtain the basic equipment and infrastructure necessary to participate in the globalizing information based society. America Online was the first corporation to respond to the appeal, and committed to fund at least 120 community information centers ("Peace Packs") in 2001 and 2002. Number and Percent of Volunteers in IT by Sector
In Africa, all countries but one reported Volunteer activities in support of host country efforts to integrate information and communications technologies (ICTs). Education and Small Business Development projects have afforded the greatest number of Volunteers the opportunity to do so. The percentage of ICT activity in Education (40 percent) corresponds roughly to the percentage of all Africa Volunteers in that sector. The percentage of Business Volunteers in ICTs (28 percent) is considerably higher than the percentage of all Africa Volunteers in that sector. The phenomenon of community radio in Mali and other countries has perhaps increased the percentages of Health (18 percent) and Environment (11 percent) Volunteers in ICTs. The same five country programs (PC/Cape Verde, PC/The Gambia, PC/Ghana, PC/Kenya, and PC/Zimbabwe) are the leaders in ICT integration as they were in FY 1999. With few exceptions, however, most other posts demonstrated a marked increase in interest and activity Benin: A Small Enterprise Development Volunteer worked with the CLCAM (credit union) in Tanguieta, Benin, which, like most other credit unions, had no computerized system for tracking credit. Professional time was wasted in hand preparation of accounts and statements, delaying the recovery of bad debts by two months or more. The PCV created a database as a solution to this issue. The results of his efforts were noted by the head of the credit union national federation, who said, "He revolutionized our . way of working. Thanks to the computerization of credit tracking it is faster and easier to prepare financial statements and to identify those who are late in making payments and to take the necessary corrective actions." Burkina Faso: Two Volunteers assigned as mathematics and science teachers in the northern and eastern regions of Burkina Faso have a common goal of promoting information technology, even though they work at sites almost 500 kilometers apart. They are convinced that technology awareness and access to information are becoming an increasingly important part of literacy. They support technology efforts in their schools and at regional levels, and are transferring computer and internet skills to Counterpart teachers and students. They also used their expertise for software and hardware troubleshooting. One of the PCVs facilitated the donation of 10 old computers from the U.S. Embassy to her school. She also secured one laptop from her church for her Counterpart. To foster collaboration, the PCV organized a meeting with 15 colleagues to assess the status of the four participating schools in terms of talents and skills among teachers, available equipment in schools, and support the Ministry of Education and local nongovernmental organizations (NGOs.) Following the meeting, the PCV participated in the Peace Corps IT conference in The Gambia and brought back useful ideas to be shared with her fellow Volunteers and teachers. Enthused with the PCV's initiative, the regional director of the northern region sent a letter to the Peace Corps asking for more support in this area. Cameroon: Volunteers taught computer science in five different secondary schools and at the Advanced Teacher Training College in Bambili. They taught about 860 students and 23 Cameroonian teachers the use of the world wide web and email. They organized a workshop with the Ministry of Education at which 10 Volunteers and 72 Counterparts were trained in computer use, email, and data entry, and were introduced to the web and to Global Positioning System (GPS) technology. Workshop participants are now using all these acquired techniques and expertise in implementing the GLOBE program in 11 schools in Cameroon. They share atmospheric and other scientific information with other GLOBE schools throughout the world and receive GLOBE scientific information from other countries. Over 40 Cameroonian mathematics and science teachers are now using the GLOBE protocols to provide handson science practical in the schools. Kenya: Small Business Development Volunteers teach basic computer literacy at the Institutes of Technology. The majority of Volunteers have ventured into other IT related activities such as web site development, internet training, setting up of computer training centers and cybercafes, market linkages through the internet, and use of digital cameras to post products on the internet. Fifteen Volunteers and 15 Counterparts participated in an IT Training of Trainers workshop to upgrade their skills as computer instructors. Two computer training centers have been set up. Over 500 students have benefited from IT training by the Volunteers. Fifteen Counterparts have continued to provide computer literacy training to staff, students, and community leaders in various parts of the country. One Volunteer acquired 1,000 donated computers from a college in the U.S. for distribution to Kenya schools. Another Volunteer acquired donated computers from the U.S. and set up a training center within a community library. A Volunteer worked with a shoemaker to improve the design of a sandal. To meet the quality and standard determined by the e commerce partner, World2Market, the PCV connected the shoemaker with Namayiana Maasai women's group. They produced beaded sandals and exported them to the U.S., making a profit of $400. The PCV then demonstrated another ecommerce tool. He showed the group how to put the item up for sale on eBay, the internet auction house, using digital photos. The sale of one item fetched a profit of $14. The women have learned and appreciated the importance of ecommerce in expanding the market for their products. They have also learned that it pays to be creative. Working in collaboration with a VSO (British) volunteer, a PCV helped sponsor selling of crafts on a website (www.globalcrafts.co.uk) that features products from Ziwa, Pendera weavers, and Temak women's group in the lake town of Kisumu, Kenya. The Volunteers showed the groups how to take photos of the products, gather prices, create a web site, establish systems for credit card use, and to fill the orders. Similar groups working with Volunteers have been invited to sell crafts on the site. In addition, the PCV has undertaken to upgrade a computer center at her site, Kisumu. The center's main objective is to train unwed single mothers as well as to generate revenue through training community members. The computer skills will enable the 30 members of TEMAK (Teenage Mothers Association of Kenya) to be more competitive in the job market. Mali: A Volunteer in the town of Kita, in western Mali, is working with a cooperative of physically handicapped individuals to coordinate artisan activities. He also works with a local hotel to help establish an internet cafe. The association is donating its computer for use by the internet cafe in return for a percentage of the overall profits. The handicap cooperative is planning on using the internet to market its products on line. Prior to this initiative, internet services were only available in the capital city, Bamako. This type of work by Volunteers is opening up world markets to small artisans and associations as well as giving the people of rural Mali unprecedented access to information. Senegal: Senegal has one of the most developed telecommunications infrastructures in Africa. Volunteers serve with NGOs that work with IT and community cybercenters. They have assisted with cybercenter startups, initiated internet, word processing, and spreadsheet training, and participated in radio programming. They support local government efforts to better manage their resources with IT tools such as GPS. PC/Senegal has initiated a partnership with the Association of Telecenters in Senegal. The Gambia: Information Technology programs in The Gambia have recently blossomed due to the combined efforts of several Volunteers. One is a mathematics and science teacher who taught chemistry and physics to Grade 10 and 11 students at Gambia High School in Banjul, the capital, during his first year of service. This academic year, he is devoting his service to introducing Information Technology in Gambian schools. First, he and two fellow Volunteers conducted a countrywide survey of all high schools, health offices, and education offices to assess the current amount of equipment, access, and needs. The results of this survey, the first of its kind in The Gambia to date, have been distributed to schools, government offices, and NGOs in an attempt to foster collaboration and aid the Gambian Government in its efforts to infuse computers into school curriculum. The PCV established an Information Technology Consortium and also edits a new IT newsletter for Volunteers in The Gambia and other West African countries. He is currently working to increase student access to computers at six schools in the vicinity of the capital. Based on the dialogue with each school, the PCV proposed six different approaches to providing basic computer instruction to high school students. Nearly 250 students and 12 teachers, about 50 percent of whom are female, have already been directly involved in these six test projects. In six months, he intends to compare the strengths of the different approaches in a report intended to help the Department of State for Education incorporate computers into the Gambian curriculum.
