The figures below are illustrations of two motherboards apart from the default CPU
motherboard that can be used with the 4100 NIC.
• The 565-274 Master Motherboard holds two daughter cards: the 4100 master
controller card and the 4100 NIC.
• The 565-275 Class B Motherboard holds the 4100 NIC by itself.
