In the past, the only way to resolve conflicts manually was to take the cover off your system and start changing switches or jumper settings on the adapter cards. Fortunately, this is a bit easier with plug-and-play because all the configuration is done via the Device Manager software included in the operating system. Although some early plug-and-play cards also had jumper switches or setup options to enable them to be configured manually, this feature was found primarily on ISA PnP-compatible cards.

Be sure you write down or print out your current system settings before you start making changes. That way, you will know where you began and can go back to the original configuration (if necessary).

Finally, dig out the manuals for all your adapter boards; you might need them, particularly if they can be configured manually or be switched to PnP mode. Additionally, you could look for more current information online at the manufacturers' websites.

Now you are ready to begin your detective work. As you try various resource settings, keep the following questions in mind; the answers will help you narrow down the conflict areas:

  • When did the conflict first become apparent? If the conflict occurred after you installed a new adapter card, that new card probably is causing the conflict. If the conflict occurred after you started using new software, the software probably uses a device that is taxing your system's resources in a new way.

  • Are there two similar devices in your system that do not work? For example, if your modem, integrated serial ports, or mousedevices that use a COM portdo not work, chances are good that these devices are conflicting with each other.

  • Have other people had the same problem, and if so, how did they resolve it? Public forums, such as those on CompuServe, Internet newsgroups, and America Online, are great places to find other users who might be able to help you solve the conflict.

Whenever you make changes in your system, reboot and see whether the problem persists. When you believe that you have solved the problem, be sure to test all your software. Fixing one problem often seems to cause another to crop up. The only way to ensure that all problems are resolved is to test everything in your system.

One of the best pieces of advice I can give you is to try changing one thing at a time, and then retest. That is the most methodical and the simplest way to isolate a problem quickly and efficiently.

As you attempt to resolve your resource conflicts, you should work with and update a system-configuration template, as discussed in the following section.

1. How to choose a Tape Backup Drive
Choosing a tape backup drive can be a simple job if you need to back up a single standalone system with a relatively small hard drive. The decision becomes more complex if the system has a larger hard drive or if you must back up a desktop system as well as a laptop. Choosing a tape backup drive type can be an even more complex program if you must back up a network server's hard drives and perhaps even back up the workstations from the server. As you ponder which backup tape drive you should select, consider the following facto...

2. DVD Copy Protection
DVD video discs employ several levels of protection that are mainly controlled by the DVD Copy Control Association (DVD CCA) and a third-party company called Macrovision. This protection typically applies only to DVD-Video discs, not DVD-ROM software. So, for example, copy protection might affect your ability to make backup copies of The Matrix, but it won't affect a DVD encyclopedia or other software application distributed on DVD-ROM discs. Note that every one of these protection systems has been broken, so with a lit...

3. Hard Drive Advancements
In 1957, Cyril Northcote Parkinson published his famous compilation of essays titled Parkinson's Law, which begins with the statement, "Work expands so as to fill the time available for its completion." A corollary of Parkinson's most famous "law" can be applied to hard drives: "Data expands so as to fill the space available for its storage." This, of course, means that no matter how big a drive you get, you will find a way to fill it. I know that I have lived by that dictum since purchasing my first hard disk drive more than 2...

4. How Magnetic Fields Are Used to Store Data
All magnetic storage devices read and write data by using electromagnetism. This basic principle of physics states that as an electric current flows through a conductor (wire), a magnetic field is generated around the conductor. Note that electrons actually flow from negative to positive as shown in the figure, although we normally think of current flowing in the other direction Electromagnetism was discovered in 1819 by Danish physicist Hans Christian Oersted, when he found that a compass needle would deflect away from p...

5. Hard Disk Form Factors
The cornerstone of the PC industry has always been standardization. With disk drives, this is evident in the physical and electrical form factors that comprise modern drives. By using industry-standard form factors, you can purchase a system or chassis from one manufacturer and yet physically and electrically install a drive from a different manufacturer. Form factor standards ensure that available drives will fit in the bay, the screw holes will line up, and the standard cables and connections will plug in. Without these indus...

6. Magneto Optical Drives
One of the most neglected types of removable-drive technologies is the magneto-optical (MO) drive. Introduced commercially in 1985, magneto-optical drives are now available in capacities exceeding 9GB. Two sizes of magneto-optical media and drives are available for desktop computers: 3 1/2" and 5 1/4". The 3 1/2" drives have capacities up to 2.3GB, and the 5 1/4" drives have capacities up to 9.1GB. 12" MO drives are also available for enterprise systems. Originally, magneto-optical drives were strictly WORM (write once, r...

The most important decision you can make after you choose the tape standard and capacity of your backup tape drive is the backup software you will use with it.
