Chapter 3 Award BIOS Setup 61
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.
SDRAM CAS Latency Time
When synchronous DRAM is installed, you can control the
number of CLKs between when the SDRAMs sample a read
command and when the contoller samples read data from the
SDRAMs. Do not reset this field from the default value specified
by the system designer.
Memory Hole at 15M-16M
You can reserve this area of system memory for ISA adapter ROM.
When this area is reserved, it cannot be cached. The user informa-
tion of peripherals that need to use this area of system memory
usually discusses their memory requirements.
