1
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 a multitasking environment, choosing the Minimized 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.
2
Full duplex operation is possible only when used in an environment where the hub or a switch
supports it. Do not enable the Full Duplex option unless your hub is set for full duplex.
To change software option settings, follow these steps:
1 Make sure that you have booted the computer under DOS,
version 6.x or later, and that your computer is connected
to the network (refer to Chapter 2).
2 Insert the 3C59X EtherDisk diskette in a floppy drive on
your computer and make that drive the current drive.
For example, if the diskette drive is A, type the following
command:
A: [Enter]
