Memory Hole at 15M-16M
In order to improve performance, certain space in memory can be
reserved for ISA cards. This field allows you to reserve 15MB to 16MB
memory address space to ISA expansion cards. This makes memory from
15MB and up unavailable to the system. Expansion cards can only access
memory up to 16MB. By default, this field is set to Disabled.
PCI 2.1 Compliance
Concurrent PCI allows multiple PCI transfers from the PCI master buses
to memory to CPU. By default, this field is set to Disabled.
Power-Supply Type
This field allows you to select the type of power supply used. The settings
are Auto, P8&P9, or ATX. The default setting is Auto.
P8&P9 AT power supply type.
ATX ATX power supply type
CPU Warning Temperature (option)
The onboard hardware thermal sensor monitors CPU temperature
changes and prevents the CPU from overheating. Alert is sounded
through the speaker and CPU speed slows down when the temperature
exceeds the assigned warning temperature until the temperature falls
below a safe level.
Current System and CPU Temperature (option)
These fields show the current system and system temperature as
monitored by the sensor under the CPU. This is a function of the System
Hardware Monitoring Device.
CPU Fan Speed (option)
These fields show the RPM (revolution per minute) status of your CPU
fan and Chassis fan. This is a function of the System Hardware
Monitoring Device.
Voltage Monitoring (option)
These fields show the monitored current voltages in the voltage
regulators and the system's power supply. This is a function of the
System Hardware Monitoring Device.
