BIOS User's Manual
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 PCI IDE is en-
abled. If all IRQs are set to ISA/EISA and IRQ14 and 15 are allo-
cated to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. This is because at least one IRQ must be avail-
able for PCI and PnP devices.
The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe
default settings 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 Disabled.
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 C8000.
2-1-6 Peripheral Setup
OnBoard FDC
This option enables the FDC (Floppy Drive Controller) on the
motherboard. The settings are Auto (AMIBIOS automatically deter-
mines if the floppy controller should be enabled), Enabled, or Dis-
abled. The Optimal and Fail-Safe default settings are Auto.
