Video BIOS Cacheable

System BIOS Cacheable

These two items allow the system and video BIOS to be cached for faster performance. We

recommend that you leave these items at the default value Enabled.

Memory Hole at 15M-16M

This item can be used to reserve memory space for some ISA cards that require it. We

recommend that you leave this item at the default value Disabled.

AGP Aperture Size

This item defines the size of the aperture for the Accelerated Graphics Port. The aperture is

a portion of the PCI memory address range dedicated for graphics memory address space.

Right Side Items

The items on the right side of the Chipset Features option are concerned with monitoring

certain temperatures, voltages, and so on in your system. These items do not function

unless you have installed an optional system monitoring chip on your mainboard.

Power Management Setup Option

This option displays a table of items which lets you control the power management of

the system. Modern operating systems take care of much of the routine power

management. This mainboard supports ACPI (advanced configuration and power

interface).

This system supports three levels of power-saving modes; doze mode, standby mode,

and suspend mode. Standby mode uses less power than doze mode and suspend mode

uses the least power.

The power management in the setup utility lets you specify a timeout for each of the

power-saving modes, and a timeout for a hard disk drive power down. A timeout,

means a period of time when the system (or the hard disk drive) is inactive. If the

timeout completes, the system power-saving mode will execute, or the hard disk drive

will power down.

You can resume from the power-saving modes by carrying out any of the activities

which are enabled in the list **PM Events**. If the hard disk has been powered down

it will automatically resume to full power when an access to the hard disk is required

(this takes just a few seconds).
