Configuration Conflicts

Sample Applications

Some optional devices provide small applications or sampler files. These applications demonstrate the capabilities of the device and serve as software examples for programming the device. Refer to the documentation that came with the option for additional information.

Configuration Conflicts

The resources used by your server consist of IRQs, DMA channels, I/O ports (for example, serial and parallel), and memory. This information is useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

ŸAn installed device requires the same resource as another device. (For example, if you install an ISA network adapter and an EISA network adapter, both requesting IRQ 5, you can configure only one of the adapters.)

ŸA device resource is changed (for example, changing jumper settings).

ŸA device function is changed (for example, assigning COM 1 to two different serial ports).

ŸAn installed software program requires the same resource as a hardware device (for example, a device driver that uses the address required by the SVGA video controller).

The steps required to resolve a configuration error depends on the number and variety of hardware devices and software programs that you install. If a hardware configuration error is detected, a configuration error message appears after the server completes POST, but before the operating system starts. You can bypass the error or start one of the configuration utility programs. Press Esc to bypass the error and load the operating system. Press F1 to start the Setup program. To start the SCU program, insert the diskette in the diskette drive and press F1. If the System Configuration Utility program resides on a hard disk drive, type SCU from a DOS prompt for the appropriate drive.
