Chipset Features Setup
This section allows you to configure the system based on the specific features of the
chipset. This chipset manages bus speeds and access to system memory resources,
such as DRAM (SDRAM). It also coordinates communications between the
conventional ISA bus and the PCI bus. It must be stated that these items should
never need to be altered. The default settings have been chosen because they
provide the best operating conditions for your system. The only time you might
consider making any changes would be if you discovered that data was being lost
while using your system.
