IBM PRO/100 SP Modem User Manual


 
1. From the Windows 98 desktop, right-click on My Computer and
choose Properties.
2. The System Properties window opens. 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 82550 LAN controller off in shutdown
under ACPI power management mode, leave this setting at 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 might 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 transmitted.
Default: 1
Range: 1 255
Adaptive Technology
The recommended value for this is 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
The recommended value for Adaptive Transmit Threshold is 16. This 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 will not attempt early
transmits.
