Network Driver Optimization Specifies how to optimize the network driver for your network by
allowing trade-offs between network performance and CPU utilization.
■ Normal balances CPU utilization and network performance.
■ Minimized CPU Utilization saves CPU resources for other tasks.
■ Maximized Network Performance is appropriate if no other
applications are making major demands on CPU resources.

Duplex Determines if the NIC transmits data across the network in both
directions simultaneously (full-duplex) or in one direction at a time
(half-duplex).
■ Auto Select allows the NIC to automatically connect at the duplex
mode of the connected hub or switch. When you select this setting,
the Media Type is automatically set to Auto Select.
■ Full-Duplex sets the NIC to operate in full-duplex mode. To use this
setting, the switch that you are connected to must support full-
duplex. You must also manually set the NIC Media Type setting.
■ Half-Duplex sets the NIC to operate in half-duplex mode. You must
also manually set the NIC Media Type setting.
■ Auto Select
■ Full-Duplex
■ Half-Duplex
Boot PROM Enables or disables the NIC’s boot ROM (if a boot ROM is installed on
the NIC).
■ Enabled
■ Disabled
Media Type Determines the type of media your network is using.
■ Auto Select allows the NIC to automatically select the Media Type
for you.
■ If you set the NIC Duplex setting to Auto Select, the Media Type is
automatically set to Auto Select.
■ If you set the NIC Duplex setting manually, you must set the Media
Type setting manually.
