Optimization*			Maximize Network Performance
Full Duplex†		Disabled	Enabled (10 Mbps only), Disabled

*This option specifies whether to optimize the network driver for a normal environment, a minimized CPU utilization environment, or a maximized network performance environment. You may choose to use a larger percentage of CPU resources under DOS in order to improve network throughput.

In multitasking environments, choosing the Minimize CPU Utilization option saves the resources of the CPU for other tasks. If no other applications are making major demands on CPU resources, you may choose the Maximize Network Performance option.

†Full duplex operation is possible only in 10 Mbps operation when used in an environment where the switch supports it. Do not enable the Full Duplex option unless your switching hub is set for full duplex.

Changing Software Settings

To change the software option settings, follow these steps:

If this computer is an operating server, notify all users of the server to save their work and log out from the network. The Configuration and Diagnostic Program disrupts the normal operation of servers and workstations, so work that is not saved may be lost.

1Make sure the 10/100BASE-T4 PCI adapter has been properly installed in your computer.

2Boot your computer under DOS, version 3.1 or later.

3Place the EtherDisk diskette in a floppy drive on your computer and make that drive the active drive. For example:
