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.
