Using the Setup Program

Advanced Chipset Setup
When selected, it brings up the Advanced Chipset Setup subscreen.
Memory Hole
Use this option to specify an area in memory that cannot be addressed on the ISA bus.
The settings are “Disabled”, “512-640K”, are “15-16MB”. The default setting is
“Disabled”.
DRAM Timings
Choose DRAM timings from “70ns”, “60ns”, or “Manual”. When choosing “60ns”, the
system performance will be the best if you use the 60ns DRAM. If choosing “70ns”, the
system performance will not be the best but it will be more stable. If choosing “Manual”,
you can modify the options from “DRAM Refresh Rate” to “Turn-Around Insertion” and
will affect the system performance and its stability. The recommendation for user is to
change only the speed of both the “DRAM Refresh Rate” and the “ISA Clock Divisor” so
that the speed is the same as the CPU Bus Clock. If the system becomes unstable, we
recommend the user to choose the “70ns” option.
DRAM Parity Check
Choose “Disabled”, “Parity”, or “ECC”. The default is “Disabled”. If choosing Parity or
ECC, you have to use parity module for DRAM module, and ECC will do the self-
correction when there is 1 bit failure in the bank.
USB Function Enable (Optional)
Choose “Disabled” or “Enabled”. The default is “Disabled”. Set this function as indicated
in the USB Connector sector.
