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:

 An 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.)

 A device resource is changed (for example, changing jumper

settings).

 A device function is changed (for example, assigning COM 1 to

two different serial ports).

 An 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.
