Pnp/Pci Configurations - ECS 649-M2 Manual

PNP/PCI Configurations

These options configure how PnP (Plug and Play) and PCI expansion cards operate in
your system. Both the the ISA and PCI buses on the motherboard use system IRQs
(Interrup 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
motherboard to work properly. Selecting PnP/PCI Configurations on the main program
screen displays this menu:

Reset Configuration Data (Disabled)
If you enable this item and restart the system, any Plug and Play configuration data stored in the
BIOS Setup is cleared from memory.
Resources Controlled By Auto (Auto(ESCD))
You should leave this item at the default Auto (ESCD). Under this setting, the system dynamically
allocates resources to Plug and Play devices as they are required.
If you cannot get a legacy ISA (Industry Standard Architecture) expansion card to work properly,
you might be able to solve the problem by changing this item to Manual, and then opening up the
IRQ Resources submenu.
• IRQ Resources:In the IRQ Resources submenu, if you assign an IRQ to
Legacy ISA, then that Interrupt Request Line is reserved for a legacy ISA
expansion card. Press <Esc> to close the IRQ Resources submenu.
In the Memory Resources submenu, use the first item Reserved Memory Base
to set the start address of the memory you want to reserve for the ISA
expansion card. Use the section item Reserved Memory Length to set the
amount of reserved memory. Press <Esc> to close the Memory Resources
submenu.
PCI/VGA Palette Snoop (Disabled)
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.
