Reset Configuration Data: This setting allows you to clear ESCD data.
The default is Disabled
Disabled: Normal Setting.
Enabled: If you have plugged in some Legacy cards to the system and they were
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.
Slot 1 to Slot 4 Use IRQ No: These settings allow the user to specify what IRQ
will be assigned to PCI devices in the chosen slot. Options available: Auto,3,4,5,
7,9,10,11,12,14 & 15. The defaults are Auto.
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 BIOS to assign whether IRQ is with
USB or not. If you have not connect the USB device. Can release the IRQ for
other device. The default is Enabled.
Enalbed: Provides IRQ for USB device.
Disabled: Release IRQ for other device.
