C. Reset Configuration Data
When enabled the system BIOS will clear/reset the ESCD during POST. After
clearing the ESCD, the BIOS will then change this item's value to Disabled.
Otherwise, the ESCD data will become useless.
D. IRQ#/DMA# assign to
When resources are controlled manually, you can assign each system interrupt
& DMA channel for "Legacy ISA" or "PCI/ISA PnP" card used.
While using Legacy ISA Card(non-PnP ISA card), please set it's necessary
corresponding resources (INT#, DMA#) from "PCI/ISA PnP" to "Legacy
ISA."
@
All ISA non-PnP devices are legacy devices that select resources (I/O Addr.,
INT# or DMA#) by using hardware jumpers.
@
IRQ-3/4/7/12/14/15 have been set as default for on board devices (COM2,
COM1, Printer port, PS/2 mouse, IDE1 and IDE2).
E. PCI IDE IRQ Map to
This function allows user to select PC AT (ISA) interrupts or PCI IDE IRQ
mapping.
ISA: BIOS does not designate any IRQ signal to the PCI slot. This is the
default setting.
PCI-SLOT 1-4: User can designate which PCI slot (1-4) the IDE card is inserted
into. This setting is suitable for use with older PCI IDE cards that BIOS is not
able to recognize.
PCI-AUTO: BIOS automatically detects which PCI slot the PCI IDE card is
inserted into.
F. FDD IRQ Can Be Free
This function allows user to choose if the FDD IRQ is able to be freed up. The
default setting is NO and this does not allow the IRQ to be free.
G. Assign IRQ For USB
If USB is employed this function must be Enabled. Otherwise, disable this
function to optimize Windows 95 IRQ resources for other IRQ usage.
H. Assign IRQ For VGA
This function allows BIOS to make an IRQ available to VGA cards. Most
current VGA card models do not require this function to be enabled.
