Clear NVRAM [NO] 

Clear NVRAM during system boot. 
Plug & Play O/S [NO] 

This menu is to configure whether or not the Operating System installed is Plug & 
Play aware. AMIBIOS detects and enables PnP card, which is required for system 
boot. Select [No] if the Operating System (like OS/2, DOS) does not support PnP. 

Configuration options: [No] [Yes] 
PCI Latency Timer [64] 

This menu allows you to select the value in units of PCI clocks for the PCI device 
latency timer register. 

Configuration options: [32] [64] [96] [128] [160] [192] [224] [248]. 
 

When set to [Yes], BIOS assigns an IRQ to PCI VGA card if the card requests for an 
IRQ. When set to [No], BIOS does not assign an IRQ to the PCI VGA card even if 

requested. 
Configuration options: [No] [Yes] 

Palette Snooping [Disabled] 
When set to [Enabled], the palette snooping feature informs the PCI devices that an 

ISA graphics device is installed in the system so that the device can function 
correctly. Setting to [Disabled] deactivates this feature.
