Passive Release
When Enabled, CPU to PCI bus accesses are allowed during passive release.
Otherwise, the arbiter only accepts another PCI master access to local DRAM.
Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions
cycles. Select Enabled to support compliance with PCI specification version 2.1.
AGP Aperture Size (MB)
Select the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a
portion of the PCI memory address range dedicated for graphics memory address
space. Host cycles that hit the aperture range are forwarded to the AGP without any
translation. See http://www.agpforum.org for AGP information.
CPU Warning Temperature
Select the combination of lower and upper limits for CPU temperature, if your computer
contains an environmental monitoring system. If the CPU temperature extends beyond
either limit, any warning mechanism programmed into your application is activated.
Current CPU Temperature
This field displays the current CPU temperature, if your computer contains an
environmental monitoring system.
Current CPU Fan 1
Monitors the onboard Fan mounted on the CPU heat sink, if available.
Current CPU Fan 2
Monitors the Fan signal routed to the Rear I/O connector.
Voltage Monitor
Displays all onboard voltages for diagnostic purposes.
Shutdown Temperature
Select the combination of lower and upper limits for the system shutdown temperature,
if your computer contains an environmental monitoring system. If the temperature
extends beyond either limit, the system shuts down.
Recommendation for optimizing performance:
With only 64/128 MB onboard SDRAM is installed, use the following settings:
SDRAM RAS-to-CAS Delay: 2
SDRAM RAS Precharge Time: 2
SDRAM CAS latency Time: 2
If additional RAM is installed in the SODIMM socket, automatic SDRAM Control is
recommended.
Field Shutdown Temperature: this does not exist for the CP302
