The displayed configuration is based on the manufacturer's SETUP
DEFAULTS settings.
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 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.
Because of the complexity and technical nature of some of the
options, not all of the options are described here.
Auto Configuration
Auto Configuration selects predetermined optimal values of
chipset parameters. When Disabled, chipset parameters revert to
setup information stored in CMOS. Many fields in this screen are
not available when Auto Configuration is Enabled.
EDO DRAM Speed Selection
The value in this field must correspond to the speed of the EDO
DRAM installed in your system. DO NOT change the default
setting of this field, as determined by the system board manufactur-
er for the installed DRAM. This value is access speed, so a lower
value means a faster system.
EDO CASx# MA Wait State
The board designer may elect to insert one additional wait state
before the assertion of the first CASx# for page hit cycles, thus
allowing one additional clock of MA setup time to the CASx# for
the leadoff page hit cycle. Do not change from the manufacturer's
default unless you are getting memory addressing errors.
