AMI BIOS Setup
33
Plug and Play Aware OS
Set this option to Yes if the operating system installed in the computer is Plug and Play-aware.
AMIBIOS only detects and enables PnP ISA adapter cards that are required for system boot. The
Windows 95 operating system detects and enables all other PnP-aware adapter cards. Windows
95 is PnP-aware. Set this option to No if the operating system (such as DOS, OS/2, Windows
3.x) does not use PnP. You must set this option correctly or PnP-aware adapter cards installed
in your computer will not be configured properly. The settings are No or Yes. The Optimal and
Fail-Safe default settings are No.
PCI Latency Timer (PCI Clocks)
This option sets latency of all PCI devices on the PCI bus. The settings are in units equal to PCI
clocks. The settings are 32, 64, 96, 128, 160, 192, 224, or 248. The Optimal and Fail-Safe
default settings are 64.
PCI VGA Palette Snoop
This option must be set to Enabled if any ISA adapter card installed in the computer requires
VGA palette snooping. The settings are Disabled or Enabled. The Optimal and Fail-Safe default
settings are Disabled.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local bus has bus
mastering capability. The settings are Disabled or Enabled. The Optimal and Fail-Safe default
settings are Disabled.
OffBoard PCI IDE Card
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 motherboard where the offboard PCI IDE
controller card is installer. If an offboard PCI IDE controller is used, the onboard IDE controller
on the motherboard is automatically disabled. The settings are Auto, Slot1, Slot2, Slot3, Slot4,
Slot5 or Slot6.
If Auto is selected, AMIBIOS automatically determines the correct setting for this option. The
Optimal and Fail-Safe default settings are Auto.
OffBoard PCI IDE Primary IRQ
This option specifies the PI interrupt used by the primary IDE channel on the offboard PCI IDE
controller. The settings are Disabled, INTA, INTB, INTC, INTD, or Hardwired. The Optimal and
Fail-Safe default settings are Disabled.
OffBoard PCI IDE Secondary IRQ
This option specifies the PCI interrupt used by the secondary IDE channel on the offboard PCI
IDE controller. The settings are Disabled, INTA, INTB, INTC, INTD, or Hardwired. The
Optimal and Fail-Safe default settings are Disabled.
