SYSTEM BOARD
AWARD BIOS SETUP

Reset Configuration Data :
Disabled : The system BIOS will do nothing.
Enabled : The system BIOS will clear/reset the ESCD during “POST”. After clearing
the
ESCD, the system BIOS will then change this item‘s value back to
“Disable”,
otherwise, the ESCD will become useless.
There are only 15 IRQs and 8 DMAs available on the mainboard and most of them are
assigned for some specific purposes. Sometimes, user may feel like to have some more
IRQ and DMA in order to install the new add on cards. In this case, you may use this
field to assign some certain IRQ and DMA to “PCI/ISA PnP” so that the new add on
card will find the free IRQ or DMA available for it.
Legacy : The system BIOS will skip and never assign the specified IRQ/DMA
ISA
resource to PCI or ISA PnP devices and the IRQ and DMA can only be sued
by their specified Legacy ISA cards.
PCI/ISA:
When the “PCI/ISA PnP” is been selected, the related IRQ and DMA
PnP
will be released and they can be used by other PCI or ISA devices.
Whenever there is the new PCI or ISA devices plugged onto the
mainboard, the system BIOS will detect it and assign a free IRQ or DMA
for the new devices.
.Note: Most IRQ and DMA have its own purpose and they can not be assigned to
“PCI/ISA PnP”. For example, IRQ14 and IRQ15 is used by the onboard IDE
device. If you change the setting on IRQ14 and IRQ15, you will be unable to
connect the hard disk drive or CD ROM drive to the IDE interface on the
mainboard. So please make sure to check the IRQ and DMA assignment in
your system before you proceed to do the setting. For instance, if you do not
have the printer (IRQ7) or PS/2™ mouse (IRQ12) connected to your PC
system, you may assign IRQ7 and IRQ12 to “PCI/ISA PnP” so that you can
have more IRQs available for new add on cards.
