2. i960 Bridge Setting

The secondary PCI slots can function as standard PCI slots when the i960 is set

to “Bridge” mode. When the i960 is set to “I2O” mode, the secondary PCI slots

are controlled by the i960 and only intelligent I/O (I2O) cards can be used on the

secondary PCI slots. An i960 memory module is required for the “I2O” mode.

3. i960 Local DRAM RAS Setting

When the i960 is set to I20 mode, the i960 chip acts as a processor and at least

one SIMM memory module is required. When using a single memory module,

this jumper does not need setting but must be installed in i960 SIMM1. When

using two memory modules, this jumper needs to be set according to the number

of sides used by the chips mounted on the memory modules.
