What should I do if a yellow 
exclamation point appears next 
to the 3C905B-TX NIC name?

1 In the Device Manager, double-click 

Other Devices.

2 Click PCI Ethernet Controller or the duplicate 

3C905B-TX NIC entry.

3 Click Remove.

4 Restart your PC.

What is the hardware IP header 
checksum?

The header checksum is a field in the IP header. 

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 
NetWare versions 3.11 or 4.0x?

The 3C905B-TX does not support NetWare 
versions 3.11 or 4.0x. These versions require the 
use of a server driver that conforms to the 
HSM 3.2 specification. 3Com no longer develops 
NetWare server drivers to the HSM 3.2 
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 
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.

What can wake up the 
3C905B-TX NIC?

The NIC can be awakened by a Magic Packet 
wake-up packet sent by management software, 
or by connecting or disconnecting the TP cable.
