3.6 PnP/PCI Configurations

This section allows configuring PnP / PCI resources.
Init Display First
This BIOS feature allows you to select whether to boot the system using the PCI Express
graphics card or the PCI graphics card. This is particularly important if you have PCI Express
and PCI graphics cards but only one monitor.
If you are only using a single graphics card, then the BIOS will detect it as such and boot it up,
irrespective of what you set the feature to. However, there may be a slight reduction in the
time taken to detect and initialize the card if you select the proper setting for this BIOS feature.
For example, if you only use a PCI Express graphics card, then setting Init Display First to
PCIEx may speed up your system's boot-up process.
Therefore, if you are only using a single graphics card, it is recommended that you set the Init
Display First feature to the proper setting for your system (PCIEx for a PCI Express card and
PCI Slot for a PCI card).
However, if you are using multiple graphics cards, it is up to you to choose which card you
want to use as your primary display card. It is recommended that you select the fastest
graphics card as the primary display card.

Reset Configuration Data
If you install a new piece of hardware or modify your computer's hardware configuration, the
BIOS will automatically detect the changes and reconfigure the ESCD (Extended System
Configuration Data). Therefore, there is usually no need to manually force the BIOS to
reconfigure the ESCD.
However, the occasion may arise where the BIOS may not be able to detect the hardware
changes. A serious resource conflict may occur and the operating system may not even boot
as a result. This is where the Reset Configuration Data BIOS feature comes in.
This BIOS feature allows you to manually force the BIOS to clear the previously saved ESCD
data and reconfigure the settings. All you need to do is enable this BIOS feature and then
reboot your computer. The new ESCD should resolve the conflict and allow the operating
system to load normally.
Please note that the BIOS will automatically reset it to the default setting of Disabled after
reconfiguring the new ESCD. So, there is no need for you to manually disable this feature after
rebooting
