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].
[AGP/PCI] The system initializes the installed AGP card first. If an
AGP card is not available, it will initialize the PCI VGA card.
[PCI/AGP] The system initializes the installed PCI VGA card first. If a
PCI VGA card is not available, it will initialize the AGP card.
[PCI/Int-VGA] The system initializes the installed PCI VGA card first. If a
PCI VGA card is not available, it will initialize the onboard
VGA device. (For 865G)
PCI IDE BusMaster
Set this option to [Enabled] to specify that the IDE controller on the PCI local bus has
bus mastering capability. Setting options: [Disabled], [Enabled].
PCI Slot1 IRQ Priority, PCI Slot2/5 IRQ Priority, PCI Slot3 IRQ Priority, PCI Slot4
IRQ Priority
These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9],
[10], [11], [Auto]. Selecting [Auto] allows BIOS to automatically determine the IRQ line
for each PCI slot.
