Two options are available: Disabled or Enabled. The default setting is
Disabled
. Normally, you should
leave this field Disabled. Select Enabled to reset Extended System Configuration Data (ESCD) when you
exit Setup if you have installed a new add-on and the system reconfiguration has caused a serious conflict
that prevents the operating system from booting.

The ESCD contains the IRQ, DMA, I/O port, memory information of the system. This is a
specification and a feature specific to the Plug & Play BIOS.
