ACPI Wake On LAN
Enables or disables the Magic Packet service for Wake on LAN when used in
Microsoft Windows 98 version 4.10.1998 without the Service Pack. If you are using
a later version of Windows 98, or have Service Pack 1 or later installed, this option
will be ignored and you will be using the ACPI Wake on LAN services.
Note: To determine your version of Windows 98: From the Windows 98 desktop,
right-click on My Computer and choose Properties. The System Properties
window appears; your Windows 98 version is listed under “System.”
Enable PME
Use this setting to adjust the power management compatibility of the adapter. The
default setting is Disable. To explicitly allow wake up with a Magic Packet from
shutdown under APM power management mode, change the setting to Enable. To
explicitly turn the 82559 LAN controller off in shutdown under ACPI power
management mode, leave the setting at to Disable.
Adaptive Inter-Frame Spacing
This is a performance setting that compensates for excessive Ethernet packet
collisions on your network. For most computers and networks, the default setting
works best, by dynamically adapting to the network traffic conditions. However, in
some rare cases you may obtain better performance by setting the spacing manually.
Setting a value forces a static gap between packets. Increasing the value increases
the delay between frames being transmitted.
Default:
1
Range:
1 – 255
Adaptive Technology
Recommended value, On
This parameter either enables or disables the Adaptive Technology performance
enhancement feature. To enable the feature, click ON. To disable the feature, click
OFF. To minimize CPU use for better system performance, leave this parameter ON.
Adaptive Transmit Threshold
Recommended value: 16.
Specifies the number of bytes before the adapter empties its internal transmit FIFO
onto the wire. The value is multiplied by 8 to produce the number of bytes. For
example, if Transmit Threshold = 200, the number of bytes is 1600. Because this is
greater than the maximum packet size for Ethernet, the adapter won't attempt early
transmits. Although this is the safest setting, the best performance is achieved when
the threshold parameter is as low as possible without producing underruns. To
experiment, set the parameter to 16. Then, if performance drops significantly,
increase the value in small increments.
Coalesce Buffers
Recommended value: 8. Range: 1 – 32.
Specifies the number of memory buffers available to the driver in case the driver
runs out of available Map Registers. This buffer area is also used when a packet
consists of many fragments. If no coalesce buffers or map registers are available, the
driver will be forced to queue the packet for later transmission. The most effective
method of transmitting data, however, is to use map registers.
Link Speed & Duplex
Recommended setting: Auto Detect (default).
This parameter lets the adapter know what speed to use on the Ethernet wire, and
how to send and receive packets, either full or half duplex. The following options
are available:
