Using the Setup Program
Plug and Play Aware O/S
The option enables the computer to boot with an operating system capable of
managing Plug and Play add-in cards. Set it to Yes if the operating system (such
as Windows 95) installed in the computer follows the Plug and Play specification.
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 the 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 the
computer will not be configured properly. The settings are No and Yes.
PCI Latency Timer (PCI Clocks)
This option sets the length of time (measured in the number of PCI clock cycles)
that a device on the PCI bus can hold the bus when another device has requested
the bus. The clock choices include every 32nd value between 32 and 248 clocks.
The settings are 32, 64, 96, 128, 160, 192, 224, and 248.
PCI VGA Palette Snoop
The option controls the ability of a primary PCI graphics controller to share a
common palette with an ISA add-in video card. The settings are Disabled and
Enabled.
Assign IRQ to PCI VGA
This option allows you to assign IRQ to PCI VGA card.
DMA Channel 0, 1, 3, 5, 6, and 7
These options allow you to reserve DMAs for legacy ISA adapter cards. The
settings are PnP and ISA.
IRQ 3, 4, 5, 7, 9, 10, 11, 14, and 15
These options set the status of the IRQ. If these interrupts are available for use
by a PCI/PnP add-in card, the interrupts are assigned for the computer to use. If
the computer contains an ISA agent that uses one of these interrupts, select ISA
for that interrupt. The settings are PCI/PnP and ISA.
