ROM PCI / ISA BIOS (XXXXXXXX)
PNP/PCI CONFIGURATION
AWARD SOFTWARE, INC.
3.6.1 PNP OS Installed
This field allows you to use a Plug-and-Play (PnP) operating system. Please set it as No if the
operating system has no PnP function or to avoid reassigning the IRQs by the operating system.
3.6.2 Resources Controlled By
Default setting is "Auto". This setting allows the BIOS to self detect setting and Plug-and-Play
devices during start up. The user can select and configure IRQs under "Manual" mode.
3.6.3 Reset Configuration Data
In case a conflict occurs after you assign the IRQs or after you configure your system, you can
enable this function to allow your system to automatically reset your configuration and reassign the
IRQs, DMAs, and I/O address.
3.6.4 IRQ-xx assigned to
If your ISA card is not PnP compatible and requires a special IRQ to support its function, set the
selected IRQ-x assigned to :Legacy ISA. This setting informs the PnP BIOS to reserve the selected
IRQ for the installed legacy ISA card.
3.6.5 DMA-x assigned to
If your ISA card is not PnP compatible and requires a special DMA channel to support its function,
set the selected DMA channel to Legacy ISA. This setting informs the PnP BIOS to reserve the
selected DMA channel for the installed legacy ISA card.
3.6.6 CPU to PCI Write Buffer
When enabled, up to four D words of data can be written to the PCI bus without interrupting the
CPU. When disabled, a write buffer is not used and the CPU read cycle will not be completed until
the PCI bus signals that it is ready to receive the data.
3.6.7 PCI Dynamic Bursting
When enabled, data transfer on the PCI bus, where possible, make use of the high-performance PCI
bust protocol, in which greater amounts of data are transferred at a single command.
3.6.8 PCI Master 0 WS Write
When enabled, writes to the PCI bus are command with zero wait states.
