IRQ14
IRQ15
These options specify the bus that the specified IRQ line is used on. These options allow you to
reserve IRQs for legacy ISA adapter cards.
These options 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 pool, the end user can use
these options 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
.
IRQ14 and 15 will not be
available if the onboard Triton II ISA PCI IDE is enabled. If all IRQs are set to ISA/EISA and
IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and PNP
devices, because at least one IRQ must be available for PCI and PnP devices. The settings are ISA/
EISA or PCI/PNP. The optimal and fail-safe default settings for all IRQs are PCI/PNP
.
Reserved Memory Size
This option specifies the size of the memory area reserved for legacy ISA adapter cards. The
settings are DISABLED, 16K, 32K, or 64K
.
The optimal and fail-safe default settings are
DIS-
ABLED.
Reserved Memory Address
This option specifies the beginning address (in hex) of the reserved memory area. The specified
ROM memory area is reserved for use by legacy ISA adapter cards.
The settings are C0000, C4000, C8000, CC000, D0000, D4000, D8000, or DC000. The optimal and
fail-safe default settings are
C4000.
Onboard SCSI
This setting enables or disables the onboard SCSI controller for those models that have the SCSI
controller integrated on the board. The settings are ENABLED or DISABLED. The optimal and
fail-safe default settings are
ENABLED.
Onboard VGA
This setting enables or disables the onboard VGA controller for those models that have the VGA
controller integrated on the board. The settings are ENABLED or DISABLED. The optimal and
fail-safe default settings are
ENABLED.
