Reset Configuration Data:
The system BIOS supports the Plug and
Play feature so the resources assigned to each peripheral have to be
recorded to prevent them from conflicting. The location to store the
assigned resources is called ESCD which is located in the system flash
EEPROM. If this option is set to “Disabled” the ESCD will update
automatically when the new configuration varies from the last one. If
set to “Enabled”, the ESCD will be cleared and forced to update and
then automatically set this option to “Disabled”.
IRQ and DMA Assigned to:
If there is a legacy ISA device which uses
an IRQ or a DMA, set the corresponding IRQ or DMA to “Legacy
ISA”, otherwise you should set to PCI/ISA PnP.
PCI IDE IRQ Map To, Primary IDE INT#, Secondary IDE INT#:
If you disable onboard PCI IDE controller and install a PCI IDE card on
the Mainboard, you need to set this option. If a PCI IDE Card uses ISA
IRQ directly thru a paddle card installed on an ISA slot, select “ISA”
for the option “PCI IDE IRQ Map To”. If a PCI IDE Card uses PCI
“INT” and is compliant to PCI Plug and Play specification, select “PCI-
AUTO” for the option “PCI IDE IRQ Map To”. Otherwise select “PCI-
SLOT n” (PCI-SLOT 1, PCI-SLOT 2, PCI-SLOT 3 or PCI-SLOT4)
depending on which slot the PCI IDE Card is installed.
Only INT A and INT B are available for a PCI IDE Card, therefore you
must set the PCI IDE Card’s primary interrupt to INT A and secondary
interrupt to INT B. The INT A is routed to IRQ 14 and the INT B is
routed to IRQ 15 thru a hardware router in the chipset.
After you have made your selections in the PnP / PCI Configuration
SETUP, press the <ESC> key to go back to the main program screen.
