MS-7058 ATX Mainboard
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values. Setting options: [32], [64], [96], [128], [160],
[192], [224], [248].
PCI Slot1 IRQ, PCI Slot2 IRQ, PCI Slot3 IRQ
These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9],
[10], [11], [12], [14], [15], [Auto]. Selecting [Auto] allows BIOS to automatically deter-
mine the IRQ line for each PCI slot.
IRQ Resource Setup
Press <Enter> and the following sub-menu appears.
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
[Reserved] setting to it. Onboard I/O is configured by AMIBIOS. All IRQs used by
onboard I/O are configured as [Available]. If all IRQs are set to [Reserved], and IRQ
14/15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI and PnP
devices. Available settings: [Reserved] and [Available].
DMA Resource Setup
Press <Enter> and the following sub-menu 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 [Reserved] setting to it.
