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"
which will detect the system resources and
automatically assign the relative IRQs and
DMAs for each peripheral.
IRQ n Resources
IRQ Resources
These fields only become available if the
Resources Controlled By field is set to
"Manual". 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 this field to
"PCI/ISA PnP".
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a
specific interrupt (Such as IRQ4 for serial port 1)
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for
