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.
Reset Configuration Data:
This option allows the BIOS to rest the Configuration Data in
the BIOS. The Optimal and Fail-Safe default setting is No.
Option
Description
No
This setting preserves the PnP data. It does not force the PnP
data to be cleared on boot. This is the default setting.
Yes
This option allows the PnP data to be rebuilt by the BIOS at every
boot.
PCI Latency Timer (PCI Clocks):
This option is used to control PCI latency timer period
(follow PCI clocks). Based on PCI specification 2.1 or later and PCI bus frequency in
system, user can select different timer to meet their PCI bus environment.
Primary Graphics Adapter:
Initialize the PCI video display card on PCI slot before
initializing any other display device on the system. Thus the PCI slot display card
becomes the primary display. Available options are [PCI] and [AGP].
DMA Channel 0/1/3/5/6/7:
These items specify the bus that the system DMA(Direct
Memory Access) channel is used. The settings determine if AMIBIOS should remove a
DMA from the available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD NVRAM. If more
DMAs must be removed from the pool, the end user can reserve the DMA by assigning an
ISA/EISA setting to it.
IRQ3/4/5/7/9/10/11/14/15:
These items specify the bus where the specified IRQ line is
used. The settings 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 IRQ
pool, the end user can use these settings to reserve the IRQ by assigning an ISA/EISA
setting to it. Onboard I/O is configures by AMIBIOS. All IRQs used by onboard I/O are
configured as PCI/PnP. If all IRQs are set to ISA/EISA, and IRQ14/15 are allocated to the
onboard PCI IDE, IRQ9 will still be available for PCI and PnP devices. Settings: ISA/EISA
and PCI/PnP.
Reserved Memory Size :
This option specifies the size of the memory area reserved for
legacy ISA adapter cards. The settings are Disabled, 16K, 32K, or 64K. The optimal
and Fail-Safe default settings are Disabled.
