you may not see a printer listed, although you know one is attached to the computer. Instead, the printer is listed as a parallel port. The computer recognizes the parallel port as LPT1, which is an address that tells the computer where to send outgoing information and where to look for incoming information. Because the printer is a parallel communications device, the computer recognizes the printer by its LPT1 address and identifies it as a parallel port. One of the Main Menu options is already highlighted. You can move the highlight from one option to another by pressing the left- or right-arrow key. As you move from one menu option to another, a brief explanation of the highlighted option appears on the bottom line of the screen. If you want more information about a test group or subtest, move the highlight to the About option and press . After reading the information, press the key to return to the previous screen. Eight options are listed in the Main Menu of the diagnostics main screen: Run, Select, Subtest, Options, Test Limits, About, Key-Help, and Quit. (An additional option, Display the Run Menu, returns you to the Diagnostics Menu shown in Figure 5-1.) NOTE: Before running any test groups or subtests (by selecting Run), you should consider setting global parameters within the Options option. They offer you greater control over how the test groups or subtests are run and how results are reported. There are two ways to select a menu option: Look on the screen to see which letter in the option is capitalized, and type that letter (for example, type r to select the Run option). Move the highlight to the option you wish to select by pressing the left- or rightarrow key, and then press . Whenever one of the eight options is selected, additional choices become available. The following subsections explain the menu options as listed from left to right in the Main Menu. Run displays five options: One, Selected, All, Key-Help, and Quit Menu. If you select One, all the subtests within the highlighted test group are run. If you choose Selected, only the selected test groups or the subtests that you selected within the test groups are run. If you select All, all of the subtests in all of the test groups are run. (The test groups or subtests are run in the same order as they are listed.) The Key-Help option displays a list of key controls available for the particular option you have chosen. The Quit Menu option returns you to the previous menu. Running the Dell Diagnostics 5-5
