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 IRQ Actived By
Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt
specifies Edge-triggered interrupts.
F. 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.
G. 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 Yes and this does not allow the IRQ to be free.
H. Used MEM base addr
This function devotes a space of memory (8K, 16K, 32K, 64K) for any peripheral
that has a high memory requirement. This is also used to designate memory
space for legacy ISA cards. The settings C800~DC00 are used to to designate
point at which the memory will start being used. The default setting is N/A
(disabled.)
