PCI VGA Palette Snoop
The options for this setting are Disabled and Enabled. When set to
Enabled, multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device.
Bit 5 of the command register in the PCI device configuration space is the
VGA Palette Snoop bit (0 is disabled). For example, if there are two
VGA devices in the computer (one PCI and one ISA) and this option is
disabled, data read and written by the CPU is only directed to the PCI
VGA device's palette registers. If Enabled, data read and written by the
CPU is directed to both the PCI VGA device's palette registers and the
ISA VGA palette registers. This will permit the palette registers of both
devices to be identical. This option must be set to Enabled if any ISA
adapter card installed in the system requires VGA palette snooping.
PCI IDE Busmaster
The options for this setting are Disabled and Enabled . Set to Enabled to
specify the IDE Controller on the PCI bus has bus mastering capabilities.
Under Windows 95/98/2000/NT and OS/2, you should set this option to
Disabled and install the Bus Mastering driver.
Offboard PCI IDE Card
This setting specifies if an offboard PCI IDE controller adapter card is
installed in the computer. The PCI expansion slot on the motherboard
where the offboard PCI IDE controller is installed must be specified. If an
offboard PCI IDE controller is used, the onboard IDE controller is automati-
cally disabled. The options are Auto (AMIBIOS automatically determines
where the offboard PCI IDE controller adapter card is installed), Slot 1 ,
Slot 2 , Slot 3 , Slot 4, Slot 5 and Slot 6 .
This setting forces IRQ14 and IRQ15 to a PCI slot on the PCI local bus.
This is necessary to support non-compliant ISA IDE controller adapter
cards. If an offboard PCI IDE controller adapter card is installed in the
computer, you must also set the Offboard PCI IDE Primary IRQ and
Offboard PCI IDE Secondary IRQ options.
Offboard PCI IDE Primary IRQ
Offboard PCI IDE Secondary IRQ
These settings specify the PCI interrupt used by the primary (or second-
ary) IDE channel on the offboard PCI IDE controller. The options are
Disabled , Hardwired , INTA , INTB , INTC and INTD .
