This is a setting used to setup hardware from the Bios.. Below is a note

from Award Software that notes the setting for ESCD...

--
Normally, you 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 such a serious conflict
that the
operating system cannot boot.

Hope this is of help!
