recorded into ESCD (Extended System Configuration Data), you can set this field
to Enabled in order to clear ESCD.
IRQ-3 to IRQ-15 assigned to: These settings allow IRQ’s to be reserved for Legacy
ISA device use exclusively or be available for use with PNP devices. These options
are only displayed if “Resources Controlled By” is set to manual.
DMA-0 to DMA-7 assigned to: These settings allow DMA’s to be reserved for
Legacy ISA device use exclusively or be available for use with PNP devices. These
options are only displayed if “Resources Controlled By” is set to manual.
Used MEM base addr: The Used MEM base addr (CB00, CC00, D000, D400,
D800, DC00) and Used MEM Length (8K, 16K, 32K, 64K) are used to support some
specific ISA Legacy cards with requested memory space below 1M address. Now
with these two functions, users can define where the used memory address is located
and its length of the legacy area that is used by the legacy device to avoid the
memory space conflict. For example, if you select “D000” for Used MEM base addr”
and “16K” for “Used MEM Length”, that means the address region D000H-D3FFFH
is occupied by ISA legacy cards, and thus BIOS will not assign this region for PnP/
ISA and PCI cards. The default is N/A.
Assign IRQ for USB: This item allows the BIOS to assign an IRQ to the USB
controller. If no USB devices are used in the system this can be set to “disabled” to
free an IRQ for other uses. The default is Enabled
• Disabled: Release IRQ for other device.
• Enabled: Provides IRQ for USB device.
Load Setup Defaults
The “LOAD SETUP DEFAULTS” function loads the system default data directly
from ROM and initializes the associated hardware properly. This function will be
necessary only when the system CMOS data is corrupted.
