AWARD BIOS SETUP

Reset Configuration Data :
Disabled : The system BIOS will do nothing.
Enabled : The system BIOS will clear/reset the ESCD during "POST". After clearing
the
ESCD, the system BIOS will then change this item's value back to "Disable",
otherwise, the ESCD will become useless.
IRQ# / DMA# assigned to :
Legacy : The system BIOS will skip never assign this specified IRQ/DMA resource to
ISA
PCI or ISA PnP devices.
PCI/ISA: All items set to this value will make the specified IRQ/DMA have a chance to
PnP
be assigned to PCI or ISA PnP devices.
PCI IDE IRQ Map To :
(for off-board PCI ICE cards)
PCI-AUTO : The BIOS will scan for PCI IDE devices and determine the location of
the
PCI IDE device, then assign IRQ 14 for primary IDE INT#, and assign
IRQ 15 for secondary IDE INT#.
ISA
: The BIOS will not assign any IRQs even if PCI IDE card is found.
Because some IDE cards connect the IRQ 14 and 15 directly from ISA
slot
through a card. (This card is called Legacy Header)
PCI-SLOT1 : For the specified slot, the BIOS will assign IRQ 14 for primary IDE
INT#, to
and assign IRQ 15 for secondary IDE INT#.
PCI-SLOT4
Note : No matter the item "Resources Controlled By" is set to "Manual" or "Auto", the
system BIOS assign IRQs to PCI devices from high to low. For ISA PnP
devices,
the sequence is from low to high. IRQ 12 is always the last one
available for
PCI/PnP due to IRQ 12 is always reserves for the PS/2
mouse.
