What is the hardware IP header

The header checksum is a field in the IP header.

checksum?

When the 3C905B-TX NIC receives IP data, it

 

 

computes the IP header checksum, and if an error

 

occurred, the packet is dropped and is not passed

 

to the protocol stack. By computing the CRC

 

through hardware, the NIC can increase the

 

performance of IP traffic and reduce CPU

 

processing required by the protocol stack.

 

To avoid having the CRC computed twice (once

 

in the hardware and again in the software by the

 

protocol stack), make sure that your IP protocol

 

does not compute the CRC or if it does, disable

 

that function.

 

 

Does the 3C905B-TX NIC support

The 3C905B-TX does not support NetWare

NetWare versions 3.11 or 4.0x?

versions 3.11 or 4.0x. These versions require the

specification.

 

 

What does Remote Wake-Up do?

Remote Wake-Up powers up a PC remotely from

 

standby or suspend mode using a wake-up packet

 

that is sent through the LAN. With this method,

 

no one has to be at the PC to turn it on.

 

Remote Wake-Up is also known as Wake on LAN.

 

 

How can I tell if my PC supports

Check to see if there is a 3-pin header for the

Remote Wake-Up?

Remote Wake-Up connector located on the PC

 

motherboard and if your PC has a BIOS that

 

supports wake-up events based on LAN events.

 

If you are unsure, contact your PC vendor for

 

further details.
