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 Configura-
tion 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.”
Resources Controlled By: The default setting is “Manual” which allows
you to control IRQs and DMAs individually. The other option is “Auto”
(default) which will detect the system resources and automatically assign
the relative IRQs and DMAs for each peripheral.
