PnP/PCI Configurations
It configures how PnP (Plug and Play) and PCI expansion cards operate in your system. Both the ISA and PCI
buses on the main board use system IRQs (interrupt requests) and DMAs (direct memory access). You must set
up the IRQ and DMA assignments correctly through the PnP/PCI Configurations Setup Utility for the main board to
work properly. Selecting PnP/PCI Configurations on the main program screen displays the menu below.
PCI/VGA Palette Snoop
This item is designed to overcome problems that can be caused by some non-standard VGA cards. This board
includes a built-in VGA system that does not require palette snooping so you must leave this item disabled.
