BIOS Setup Information
PCI VGA Palette Snoop
Some display cards that are non-standard VGA such as graphics accelerations or
MPEG video cards may not show colors properly. User can choose “Enabled”
setting to correct this display mismatch problem and support any ISA adapter card
installed in the computer requires VGA palette snooping.
Allocate IRQ to PCI VGA
This option will be used to allocate IRQ for PCI VGA card. In general, some of PCI
VGA cards need IRQ support.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local bus
has bus mastering capability.
Off Board PCI IDE Primar y/Secondar y 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
