Mainboard User's Manual
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 Auto<ESCD>
which will detect the system resources and automatically assign the
relative IRQs and DMAs for each peripheral. The other option is
Manual which allows you to control IRQs and DMAs individually.
IRQ Resources: This field becomes available if the Resources Con-
trolled By field is set to Manual. Pressing <Enter> displays a list of
IRQs and their current assignments. If there is a legacy ISA device
which uses an IRQ, set the corresponding IRQ to Legacy ISA; oth-
erwise, you should set the field to PCI/ISA PnP.
DMA Resources: This field becomes available if the Resources
Controlled By field is set to Manual. Pressing <Enter> displays a list
of DMAs and their current assignments. If there is a legacy ISA de-
vice which uses an DMA, set the corresponding IRQ to Legacy ISA;
otherwise, you should set the field to PCI/ISA PnP.
PCI/VGA Palette Snoop: This item is designed to overcome some
problems that can be caused by some non-standard VGA cards. This
board includes a built-in VGA system that does not require palette
snooping so you must leave this item disabled.
Assign IRQ for USB/VGA: Names the interrupt request (IRQ) line
assigned to the USA/VGA (if any) on your system. Activity of the
selected IRQ always awakens the system.
After you have made your selections in the PNP/PCI Configuration
Setup, press the <ESC> key to go back to the main program screen.
