PCI/Plug-n-Play Setup
This section describes how to configure the PCI bus system. PCI is a system which
allows I/O devices to operate at speeds close to the CPU’s speed when they
communicate.
All of the options described in this section are important and technical and it is
strongly recommended that only experienced users make changes to the default
settings.
Plug-n-Play Aware O/S
Set this option to
Yes
if the operating system installed in the computer is
Plug-n-Play (PnP) aware. The BIOS only detects and enables PnP ISA adapter
cards that are required for the system to boot. The Windows 95/98/2000 operating
systems detect and enable all other PnP aware adapter cards and are PnP aware.
Set this option to
No
if the operating system (such as DOS, OS/2, Windows 3.x)
does not use PnP.
Clear NVRAM
This option is used to clear NVRAM and to check or update the Extended System
Configuration Data (ESCD) data after a system power on. Setting this option to
No
will not clear NVRAM. Updating the ESCD is effective in a different ESCD
data comparision. If you select the
Yes
setting, the BIOS will update the ESCD
every power on.
PCI Latency Timer (PCI Clocks)
This option is used to control the PCI latency timer period (follow PCI clocks).
Based on PCI specification 2.1 or later and the PCI bus frequency in the system,
the user can select a different timer to meet their PCI bus environment.
Note:
Set this option correctly or the PnP aware adapter cards installed in
your computer will not be configured properly.
