BIOS Setup Information
ROBO-638 User’s Manual
4-15
This option specifies if an offboard PCI IDE controller adapter card is used in the
computer. You must also specify the PCI expansion slot on the SBC (Single Board
Computer) where the offboard PCI IDE controller card is installed. If an offboard
PCI IDE controller is used, the onboard IDE controller on the SBC is automatically
disabled.
If
Auto
is selected, BIOS automatically determines the correct setting for
this option. If you want to respectively control off board PCI IDE Primary/
Secondary IRQ resources, you should set this option among
Slot 1
to
Slot 4
.
Otherwise, all of these sub-options will be not available and hidden.
Off Board PCI IDE Primary/Secondary IRQ
This option specifies the PCI interrupt used by the primary/ secondary IDE
channel on the offboard PCI IDE controller. The settings are
Disabled
,
INTA
,
INTB
,
INTC
,
INTD
, or
Hardwired
for installing off-board non-compliant PCI IDE
card.
PCI Slot 1/2/3/4 IRQ Priority
These options specify the priority IRQ to be used for any PCI devices installed in
PCI expansion slots 1 through 4. The settings are
Auto
(AMIBIOS automatically
Determines the priority IRQ), (IRQ)
3
,
4
,
5
,
7
,
9
,
10
, or
11
.
DMA Channel 0/1/3/5/6/7
These options specify if the named DMA channel is available for using on the
ISA/EISA bus or PnP (Plug & Play).
IRQ 3/4/5/7/9/10/11/12/14/15
These options specify the bus that the named interrupt request lines (IRQs) are
used on. These options allow you to specify IRQs for use by 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 PCI/PnP Setup to
remove the IRQ by assigning the option to the ISA/EISA setting. All IRQs used by
on-board I/O are configured as PCI/PnP.
