This section allows you to configure the system based on the specific
features of the installed chipset. This chipset manages bus speeds and
access to system memory resources, such as DRAM and the external
cache. 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.
DRAM Settings
The first chipset settings deal with CPU access to dynamic random
access memory (DRAM). The default timings have been carefully
chosen and should only be altered if data is being lost. Such a scenario
might well occur if your system had mixed speed DRAM chips
installed so that greater delays may be required to preserve the integrity
of the data held in the slower memory chips.
