Note:A 16-bit VGA adapter typically decodes base memory in 128KB blocks. If you are installing the NIC in a system with such a card, you may need to set the NIC block decode size to 128KB. If you set the block decode size to 128KB then all other 16-bit cards in the system must utilize 128KB decode. NIC must be in 16-bit mode for this switch to be functional. | ||

Note:Node address 0 is used for messaging between nodes and must not be used. A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch 8 is the Least Significant Bit and switch 1 is the Most Significant Bit. The switches have the following decimal values: switch 1=128, 2=64, 3=32, 4=16, 5=8, 6=4, 7=2, 8=1. Turn Off the switches and add the values of the Off switches to obtain the correct node address. (On=0, Off=1) | ||||||||
