Correction) feature. The ECC feature enables BIOS to detect and correct data
errors. Disable this parameter if you want to disregard the function. The default
setting is ECC.

Enabling this parameter allows BIOS to create a multiprocessor (MP) table for
Windows NT use. In a single-processor system running Windows NT, you may
disable this parameter to enhance system performance. If you install another
CPU for a dual system, enable this parameter then re-install Windows NT.
In cases when this parameter is enabled before installing Windows NT in a single-
processor system, you may upgrade to a multiprocessor system without
reinstalling Windows NT.
The default setting is Enabled.
