KT Mainboard BIOS
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: You should change this item to
Auto(ESCD). Under this setting, the system dynamically allocates
resources to plug and play devices, as they are required.
If you cannot get a legacy ISA (Industry Standard Architecture) ex-
pansion card to work properly, you might be able to solve the
problem by leaving this item at the default setting Manual, and then
opening up the IRQ Resources and DMA Resources sub-menus.
In the IRQ Resources sub-menu, if you change any of the IRQ assig-
nations to Legacy ISA, then that Interrupt Request Line is reserved
for a legacy ISA expansion card. Press Esc to close the IRQ R e-
sources sub-menu.
Resources Controlled By: The default setting is Manual which al-
lows you to control IRQs and DMAs individually. The other option
is Auto (ESCD) which will detect the system resources and auto-
matically assign the relative IRQs and DMAs for each peripheral.
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.
