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:
PNP OS Installed:
This item allows you to determine PnP OS is installed or
not. The default is No.
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 setting 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.
