6.5. Chipset Features Setup
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 occurs 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.
