4.6 Advanced Chipset Features
This section allows you to configure the system based on the specific features of
the Intel 82815 GMCH chipset. This chipset manages bus speeds and access to
system memory resources, such as DRAM (SDRAM) 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.

This 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.
