430TX). These options are used to change the ChipSet‘s registers.
Please carefully change any default setting ,otherwise the system
could be running un-stable.
Auto Configuration : Enable or Disable
When use the 60nS general type DRAM,please enable the setting to
get the optimal timings.
SDRAM Speculative Read : Enable or Disable
When enable this option, the PCU will send predict commands to the
SDRAM, if a miss happens, the CPU will cancel this command.
Because some OS under certain situations have problem for this
feature, it is normally disable.
Memory Hole at 15M-16M : Enable or Disable
This setting reserve 15MB to 16MB memory address space for ISA
expansion cards that specifically require this setting. Memory from
15MB and up will be unavailable to the system because expansion
cards can only access memory up to 16MB.
CPU Warring Temperature : Disable,50
..
There have a LM75 temperature sensor under the bottom of
CPU,when set the CPU Warring Tempture to a certain limit which will
help customer secure the system not burn out because of fan failed
or other accident.

4.5 Integrated Peripherals
This setup is almost working for Multi-I/O Chip(W83977F ). These
options are used to change the ChipSet‘s registers. Please carefully
change any default setting to meet your application need perfectly.
The only special concern is Onboard
Serial Port2. If you are using the IrDA port,you have to set this
port accordingly.
