3.3.4 Operation of ECC
This parameter allows you to enable or disable the error correction function. In the
option Correction Enabled, ECC automatically corrects any single-bit errors
detected. For multiple-bit errors detected, ECC issues an NMI to signal the
operating system of the multiple-bit error detection.
In the option Correction Disabled, ECC detects both single-bit and multiple-bit
errors but does not correct a multiple-bit error; it issues an NMI to signal the
operating system of the error detection.
This parameter is grayed if the ECC/Parity Mode Selection parameter is set to
either Parity or Disabled . Refer to section 3.3.3.
3.3.5 Memory at 15MB-16MB
To prevent memory address conflicts between the system and expansion boards,
reserve this memory range for the use of either the system or an expansion board.
Before setting this parameter, check your add-on card manual to determine if your
add-on card needs this memory space. If not, set this parameter to System Use.
