What is the hardware IP header		The header checksum is a field in the IP header.
checksum?		When the 3C905B-TX adapter 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 adapter 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 adapter		The 3C905B-TX adapter does not support

What does Remote Wake-Up		Remote Wake-Up powers up a PC remotely from

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

How can I tell if my PC supports Remote Wake-Up?

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