Parameter Internal Cache (CPU Cache) External Cache Cache Scheme Description Lets you enable or disable the primary cache memory, i. e. , the CPU memory. Lets you enable or disable the secondary cache memory. This parameter is non-configurable and is always set to Write-back. The Write-back mode updates the cache but not the memory (write-back mode) when there is a write instruction. To prevent memory address conflicts between the system and expansion boards, reserve this memory range for the use of either the system or an expansion board. Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter. Options Enabled or Disabled Enabled or Disabled Write-back Memory at 15MB-16MB Reserved for System or Add-on card Chapter 2 29 PnP/PCI Options The PnP/PCI Options allows you to specify the settings for your PCI devices. Selecting this option displays the following screen: The following table describes the parameters found in this sub-menu. Settings in boldface are the default and suggested settings. Parameter PCI IRQ Setting Description Allows you to automatically or manually configure the Plug-and-Play (PnP) devices installed in your system. Refer to your device manual for technical information about the PCI card. Allow you to manually assign an interrupt for each PCI device installed in your system. When the PCI IRQ Settings is set to Auto, BIOS automatically assigns the available IRQs to the PCI devices. Allows you to assign the same IRQ to two different devices. Enables the palette snooping feature if you installed more than one VGA card in the system, allowing the control palette register (CPR) to manage and update the VGA RAM DAC (Digital Analog Converter, a color data storage) of each VGA card installed in the system. The snooping process lets the CPR send a signal to all the VGA cards so that they can update their individual RAM DACs. The signal goes through the cards continuously until all RAM DAC data has been updated. This allows the display of multiple images on the screen. Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter. Lets you specify whether BIOS will initialize only PnP boot devices such as SCSI cards, or all PnP boot and non-boot devices such as sound cards. When enabled, avoids IRQ conflict when installing non-PnP and PnP ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. [. . . ] Any signal or activity detected from the Modem ring-in connector automatically returns the system to normal operation. Refer to "Jumpers and Connectors" on page 59 for the location of the Modem ring-in connector (CN17) on the system board. Wake-on LAN The Wake-on LAN (WOL) feature is a special feature that allows the system to be activated by a network connection via the onboard WOL connector (CN1). Aside from WOL, common network functions such as remote access, file sharing, etc. Refer to "Jumpers and Connectors" on page 59 for the location of the WOL connector (CN1) on the system board.
