MS-6728 ATX Mainboard

IRQ 3/4/5/7/9/10/11/14/15

These items specify the bus where the specified IRQ line is used.

The settings determine if AMIBIOS should remove an IRQ from the pool

of available IRQs passed to devices that are configurable by the system

BIOS. The available IRQ pool is determined by reading the ESCD NVRAM.

If more IRQs must be removed from the IRQ pool, the end user can use

these settings to reserve the IRQ by assigning an ISA/EISA setting to it.

Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O

are configured as PCI/PnP. If all IRQs are set to ISA/EISA, and IRQ 14/15

are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI

and PnP devices. Available settings: ISA/EISA and PCI/PnP.

Set DMAs to PnP or ISA

Press <Enter> to enter the sub-menu and the following screen appears:

DMA Channel 0/1/3/5/6/7

These items specify the bus that the system DMA (Direct Memory

Access) channel is used.

The settings determine if AMIBIOS should remove a DMA from the

available DMAs passed to devices that are configurable by the system

BIOS. The available DMA pool is determined by reading the ESCD

NVRAM. If more DMAs must be removed from the pool, the end user can

reserve the DMA by assigning an ISA/EISA setting to it.
