7.6 PCI/PLUG AND PLAY
This section is used to configure PCI / Plug and Play features. The <PCI & PNP Setup> option configures the PCI
bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value.

Figure 7-6 BIOS: PCI /Plug and Play Setup
Plug and Play Aware O/S
Set this option to Yes if the operating system installed in the computer is Plug and Play-aware. The BIOS 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 <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.
Clear NVRAM
This sets the operating mode of the boot block area of the BIOS FLASH ROM to allow programming in the Yes
setting.
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.
PCI IDE BusMaster
Enabled this option is to specify that the IDE controller on the PCI local bus has bus mastering capability.
DMA & IRQ
These options specify the bus that the named IRQs/DMAs lines are used on. These options allow you to specify
IRQs/DMAs for use by legacy ISA adapter cards. These options determine if the BIOS should remove an
IRQ/DMA from the pool of available IRQs/DMAs passed to BIOS configurable devices. If more IRQs/DMAs must
be removed from the pool, the end user can use these PCI/PnP Setup options to remove the IRQ/DMA by
assigning the option to the ISA/EISA setting. Onboard I/O is configurable by BIOS.
Reserved memory Size
This option specifies the size of the memory area reserved for legacy ISA adapter cards.
