Pnp/Pci Configurations - MSI K8MM-ILSR User Manual

MS-6741 Micro-ATX Mainboard
This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with
its special components. This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the
default settings.
Plug and Play Aware O/S
When set to Yes, BIOS will only initialize the PnP cards used for booting (VGA, IDE,
SCSI). The rest of the cards will be initialized by the PnP operating system like
Windows 98, 2000 or ME. When set to No, BIOS will initialize all the PnP cards. Select
®
Yes if the operating system is Plug & Play.
Clear NVRAM
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Random
Access Memory) is where the BIOS stores resource information for both PNP and
non-PNP devices in a bit string format. When the item is set to Yes, the system will
reset ESCD NVRAM right after the system is booted up and then set the setting of the
item back to No automatically.
PCI Latency Timer
This item controls how long each PCI device can hold the bus before another takes
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values. Settings range from 32 to 248 at a 32
increment.
