4.7. PnP/PCI Configurations
Both the ISA and PCI buses on the Mainboard use system IRQs (In-
terrupt ReQuests) and DMAs (Direct Memory Access). You must set
up the IRQ and DMA assignments correctly through the PnP/PCI
Configuration Setup utility; otherwise, the mainboard will not work
properly.
Selecting “PnP/PCI Configurations” on the main program screen dis-
plays this menu:

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 (Extended System Configuration
Data) 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 “Enable,” the ESCD
will be cleared and updated and then this option will automatically be
set to “Disabled.”
