Items Description
PNP OS Installed It sets whether the installed OS supports PnP (Plug & Play). Normally set at [Yes].
Resources
Controlled By
It sets whether PnP (Plug 6 Play) is to be performed for IRQ, DMA, I/O address and other system
resource assignations. Normally set at [Auto]. The minimal system resources are assigned and
BIOS is automatically performed when this parameter is set at [Auto], and this status is notified
to the OS to enable it to succeed to this mode. However, there are cases when automatic
setting with the PnP BIOS prevents the IRQ parameters and common parameters from being set
at the required values. In this event, change the setting to [Manual] and then make the
required settings manually with [IRQ#/DMA# assigned to] or the OS. Also, it is necessary to use
[IRQ#/DMA# assigned to] in order to make manual settings when legacy devices that do not
support Plug & Play are in use.
Reset
Configuration
Data

Configuration Data) on subsequent boot-ups. Normally set at [Disabled].This parameter will be
automatically restored to the [Disabled] setting on the next boot-up when set at
[Enabled].
