Some programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot run. Rebooting the computer can confirm whether or not these programs are the cause of the problem. Other programs use specialized subroutines called drivers that can cause problems in the computer. For example, a variation in the way the data is sent to an external monitor may require a special screen driver program that expects a certain kind of video mode or monitor. In such cases, you may have to develop an alternative method of running that particular program-for example, the creation of a boot file made especially for that program. For help with this situation, call the support service offered by the manufacturer of the software you are using. Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for the default IRQ line setting for each installed device. Then consult Table 3-2 to configure the device for one of the available IRQ lines. NOTES: Installed devices cannot share the same COM port address. The default address of the computer's serial port is COM1. To view IRQ line assignments in the Microsoft Windows 98 operating system, click the Start button, point to Settings, and click Control Panel. Double-click the System icon.

Some programs may leave portions of their setup information behind, even though
you have exited from them. As a result, other programs cannot run. Rebooting the
computer can confirm whether or not these programs are the cause of the problem.
Other programs use specialized subroutines called
drivers
that can cause problems in
the computer. For example, a variation in the way the data is sent to an external
monitor may require a special screen driver program that
expects
a certain kind of
video mode or monitor. In such cases, you may have to develop an alternative method
of running that particular program
—
for example, the creation of a boot file made
especially for that program. For help with this situation, call the support service
offered by the manufacturer of the software you are using.
