mance. This field applies only when synchronous DRAM is installed in
the system.
SDRAM RAS Precharge Time
If an insufficient number of cycles is allowed for the RAS to accumu-
late its charge before DRAM refresh, the refresh may be incomplete
and the DRAM may fail to retain data. Fast gives faster performance;
and Slow gives more stable performance. This field applies only when
synchronous DRAM is installed in the system.
SDRAM CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles of
CAS latency depends on the DRAM timing. Do not reset this field
from the default value specified by the system designer.
The following features are only available with the optional LM81 chip.
CPU Warning Temperature
Select the combination of lower and upper limits for the CPU tempera-
ture. If the CPU temperature extends beyond either limit, any warning
mechanism programmed into your system will be activated.
Current CPU Temperature
This field displays the current CPU temperature, if your computer
contains a monitoring system.
Current System Temperature
This field displays the current system temperature, if your computer
contains a monitoring system.
Current CPUFAN 1/2/3 Speed
These fields display the current speed of up to three CPU fans, if your
computer contains a monitoring system.
IN0-IN6 (V)
These fields display the current voltage of up to seven voltage input
lines, if your computer contains a monitoring system.
